Diesel Heater Diagnosis - white smoke but not lighting

[@onandforthepublicrecord624]

Just thank you... -33 Celsius in Winnipeg Canada tonight, if it wasn't for your video I would have rented a hotel tonight. I cleaned out the carbon and just reinstalled the heater. Current temp in my bus at install 0 degrees. Heater is blowin hot. I owe you a pint...or ten. Thanks again & cheers

[@soiboughtabus9563]

Well, I tore my heater apart three times before finding your video I saw 2 years ago. I had the white smoke out of the exhaust and intake. Cleaned it 3 times, more places each time, the fourth time I went directly after that little 1/8th inch ish hole by the screen, cleaned that out with carb cleaner and it fired right up. Thanks for the video, I now have a backup heater again.

[@amyh.627]

Great video! First time I understood that the reason for the white smoke is that the flame did not start and the fuel is only grilled by the glow plug, due to the blocked little hole, which causes that there is no ignition flame and no real burning of the diesel

[@DavidMcLuckie]

Yes, exactly

[@MYTFarms]

THANK YOU for posting this. Have a very similar German made heater in my mobile crane cab. Cold snap coming this week, and I really needed to get it working. Drained diesel, cleaned the line and filter, still no heat just smoke. This video finally helped me figure out what needed to be done. Took it apart and cleaned it up good this evening, and I have heat just in time for an icy work week!

[@djwanye83]

maybe a video how to on controller settings especially for fuel setting 👌😊

[@Banwell128]

Had the exact same issues, followed up his video and now works perfect! If you ever do a video with the recommended settings on your controller it would be very much appreciated 😅

[@fannyschmeler223]

Billy Connolly does night heaters !! Great videos though I have to say. Ive had a few issues myself with carbon build up . I've found there is usually some other problem that leads to premature carbon build up like low power due to battery voltage being low in first place and further volts drop through over length wiring of wrong section cable or incorrect plumbing allowing air to hide in joints , filters and pumps . Brilliant heaters when installed and used correctly though .

[@brianjohnson217]

Thank you David, I bought a Parking Heater in January this year and I'm very pleased with it. BUT! I've read so many bad comments about these CDH . Your video is very reassuring that these heaters can be easily repaired.

[@robertpostie1836]

I have tried for 2 weeks to get my heater working and no-one could give me advise to fix it but I then saw the title of this video was my problem so watched it and no-one had mentioned the little vent hole in the glow pin hole to me. I removed the glow pin, found and cleaned out the little hole and away it went. Thank you.

[@timblackman892]

Thank you sooooo much. Mine was smokey too, but after watching your video and removing a cup of carbon she now runs like a gem 🤙

[@Ralphs-House]

David, Also worth getting the burn chamber REALLY clean and bone dry by heating it up with a blow torch. Once cool, reassemble. Its amazing the clouds of smoke you'll get from very back of chamber with a blow torch (where its almost impossible to clean) and it gives an even greater chance of a successful start up. From what I've gleaned, the hidden part of the burn chamber is composed of a ring of welding blanket (carbon felt) which can absorb fuel like a wick. Its held in place with stainless steel mesh. After running rich or flooding, this felt no longer soaks up diesel because its become totally gummed up with soot and residue. It sets like concrete in there and the fuel can't catch fire and invariably drips out the exhaust or air inlet. Carb cleaner (or cellulose thinners) will definitely aid cleaning the burn chamber but the blowtorch is the surest way of restoring the absorbency of the carbon felt, and its super fast. You usually get flame out or E8 error after the white smoke which is often attributed to fuel when sometimes what it needs is a proper clean - and/or as in this case, clearing of blocked holes.

[@markcarrington9873]

Absolute brilliant video, what would we do without people like you sharing stuff on you tube, thanks

[@lmvlmv]

I had the same thing when the exhaust run on my heater in the garage was too long. Exhaust blocked and the heater got flooded. Unblocked exhaust, still a smoke machine. Figured the fuel air mix was off so I let it try to start and blew down the intake as hard as I could. Smoke, Smoke, smoke, POP! whooosh. Let it run as hot as possible and it was fine. It only took about 2 days for the smell of Diesel fog to dissipate....

[@E3CB]

Cool trick. Thanks!

[@josephjackson5330]

I have the same issues time to time I start it with egr valve spray up the intake on starting it pops and back fires then smoke and starts every time.

[@thomaslourbakos9307]

That my friend would be a good video tutorial to make

[@KevinStokes]

So... White smoke, no light, check hole. Nice video, I understand my Chinese diesel heater much better now. Thanks for making it.

[@Jasonliggett69]

Thank you for making this video. My “new” heater instantly started to act like this and your information helped me repair it. Turns out they sent me one that was FULL of debris and gunk, probably just gave me someone else’s return. SMH. You’re a lifesaver!!

[@rcampbell5836]

I don't know this man but he is a genius

[@videoben8170]

Thank you for the video! I would have never known that little air hole was there, I took out my glow plug and sure enough, it was plugged up. I removed the screen also, but that seemed ok. I've been pretty good with running mine at full blast every few days to help keep the burn chamber somewhat clean. Cheers!

[@moretrash4you]

Are you running it without the screen?

[@MrHugemoth]

A 5kw heater I've been using for a couple years began smoking on startup but always started on it's automatic second try. Internal inspection showed no carbon buildup, mesh was clean, and the small hole by the glow plug was unobstructed. The motherboard was the problem. Replacing it fixed the smoke issue.

[@Snailmailtrucker]

That's weird... I just posted my comment above. Exactly the same as yours. Mine still starts up on the 2nd. try and I have 2 other New units that I have never even fired up... I may just replace the whole unit and then dive into this one I have been using for nearly 3 years now.

[@RobertWinfrey4Jesus]

Another thank you my bunk heater quit last year it would come on click click shut off white smoke. After watching your video took it upon myself to pull it out and see if I could find the issue. It was easy got it apart that plug hole on the side you was talking about was my issue I cleaned it out, Clean the glow plug tip put it together and it fired right up. Shut it off several times to see if it continue to work and it does hot hot hot thank you so much again for your video.

[@misterfixit1908]

MY HEATER HAD LESS THAN 1 GALLON BURNED THROUGH IT ,AND I REMOVED THE GLOW PLUG AND STUCK AN L SHAPED PIECE OF WIRE THROUGH THE AIR HOLE AND CLEANED IT OUT, AND IT FIRED RIGHT UP, THANKS FOR THE INFORMATION!

[@livenloud6697]

Thank you so much for posting this video mine was chock-a-block with dust and now working perfectly thank you.. I have ordered a clean as snorkel intake for it

[@davidwilliamson7781]

Can you please explain the changes to the settings to reduce the fuel

[@MrRatkilr]

Love this vid. I purchased a diesel heater that has yet to arrive and was wondering how user friendly they were to take apart and service. I built my own waste oil heater for my shop out of scrap over a decade ago. These are not real complicated. I think I will be happy with mine.

[@darrellbrown7843]

I bought 2 new heaters, lots of soot issues, not sure why, I use an air hose to blow them out constantly..

[@joblessalex]

If you use waste oil, you really need to mix the fuel and run extremely clean oil. Any nasties and it will do this crap constantly.

[@sparkola]

If you run kerosene or even better the synthetic version every once in awhile, you’ll never have to open it up to clean it. A few capfuls of Automatic Transmission fluid in every tankful will make a world of difference

[@asdsdasdasda8040]

Came here because my heater on my Merc w211 had suddenly stopped working after we started having temperatures below 0 degrees Celsius. Fortunately I figured out the issue today and boy was it foolish. The exhaust pipe had shifted off from it's hole on the bumper and its end was surrounded with 1 cm thick ice. After tearing it off and blow torching the ice off from the tube the Eberspächer started right up, but it smoked like hell for 15 minutes meaning the entire hood area was full of smoke including some smoke on the interior as well. To help others here were my symptoms: Heater fan and glow plug started normally via remote. After 30 seconds of running the diesel pump started clicking slowly. After 1.5 minutes the diesel pump and the fan gradually went crazy to the point where the clicking was really fast and the fan was super loud. After 2.5 minutes it just shut off the diesel pump and the fan started running low and quiet. If you are experiencing same type of behaving with your heater I'd recommend you to check out the exhaust pipe from both ends.

[@leeedwards9043]

brilliant mate. having a bit of trouble with mine so you have given me some starting points to have a go at fixing it😁👍

[@sirgeorgeboy]

Thank you for the great video's I am going through them as I get time just wanted to mention something about my own experience with one of the heater's that also got full of soot after only 3 days I cleaned it and ran at full power for 4 days and it stopped working I striped it down again and cleaned as full of soot but this time I noticed my fan had 2 magnet's on it so I changed the setting SN1 to SN2 and now it runs great ... It seems the brain thought the fan was going faster than it was and delivering to much fuel , hope this helps someone,keep up the great work. HAPPY NEW YEAR 🥳

[@DavidMcLuckie]

Nice, so in reality it was getting half the air it thought it was. That's another thing I can add to my list of fault checks.

[@MrJFoster1984]

My mate adds some injector cleaner in his diesel heater and it cleaned it out well, no longer blows white smoke now 👍

[@IntelCoreI77700K]

I've thought about running Seafoam in mine as preventative maintenance. I wonder if that would work alright

[@mtn.lion_bait]

Thank you!! I was about to order a new one and drive 300 miles to the nearest shipping location

[@jaymoge]

Thank you. I've been wondering what goes on inside, it's basically a mini "salamander heater" we call it. Like a big orange job site heater with k1 in a tank on the bottom. It's like that but inside its own own heat exchanger. Brilliant

[@DavidMcLuckie]

Kind of. Salamander, Torpedo, diesel space heaters use compressed air (compressor built into fan motor) to blow (through a nozzle) a mix of air and diesel which is then ignited. These little diesel heaters use the hot surface of the burn chamber to vapourise the diesel which then mixes with the air from the fan and burns inside. So they are similar in that they burn diesel, but have a long startup and shutdown compared to the Salamander which can deliver instant heat.

[@unmountablebootvolume]

@@DavidMcLuckie Interesting! I always thought they use the same system as oil boilers and very large (>20kw) diesel air heaters, where the burner motor drives a combustion air blower and an oil pump, that sends high pressure oil/diesel to a nozzle, that sprays it into the burn chamber as a very fine mist. On such units, the air and combustion gasses are also seperated by a large tube heat exchanger.

[@alexjohn4662]

Thanks for good video. I bought one after seeing one of your videos.i have had it in my van now for over 24 months. With no problem. Thanks 😊 its a god send and for the 130 pounds I spent worth it.top branded ones are 500 plus. I even put it on when at home.why because I didn't want to de ice my windows in the morning. On a low tick over at 16 degrees. No ice and van starts 1st time.such a low battery drawer when at temperature .I thank you kind sir lol

[@S5UPERCHARGED]

This helped me loads, thanks for the video! My hole was blocked too

[@Snailmailtrucker]

Mine does that exact same thing...except mine always starts up immediately when I wait about 15 minutes and try to start it up again ! I tore it apart last week to see if I could see anything wrong... it was Super clean everywhere inside of the unit (I have used it for nearly 3 years and first time taking it apart) ! I am now guessing it must be my Glow Plug ! (I should have replaced it when I had it apart and out of my van !)

[@paulrowe-z1z]

Great video mate. A massive help to me in sorting my E10 error code. Thanks a lot.

[@Mountainman.music63]

I realize that this is 3 years old, But for other folks, remove that round thin plate that's riveted on the back of the burn chamber and it won't stop up, Giving it more air and allows the exhaust to have a lot more pressure, Solved my problem Mine wouldn't last but a day or two and stop with E-8 code, Soot everywhere, Not anymore, she works great now.

16:10 “white smoke, no light, check hole” - that should maybe go on a T-Shirt?

[@uncoolkid666]

So. I just faced down my demonic smoke belcher and might have been victorious. I blew in the intake as somebody mentioned, not plugged solid. Had already replaced glow screen and the plug today as it was damaged from overheating itself. Blasted a bunch of electronics cleaner in the glow hole followed by compressed air previously. Shot it with more tonight, rammed the plug in and set it to go. Sprayed carb cleaner up the intake a few times and got nice fireballs a few times. Noted chunks of cokey soot rattling out the exhaust. Got nicely heated up and seemed to quit smoking so bad. I had left the shroud off and it went E05 overheat which may have further contributed to self cleaning. Now its actually heating up again and all but zero smoke.... wow.

[@DavidMcLuckie]

Nice, flames out the exhaust is always a nice touch.

[@uncoolkid666]

The intake, actually. Right back in my face, inside a cargo bin under my bus. Not huge but nice. :p

[@DavidMcLuckie]

Yikes!

[@uncoolkid666]

Well hell I just got back to find it shut down again. E08. It likes that one. It ran like brand new for 2 nights after I gave it the shenanigans. Do you suspect it is still plugged up or something else? Its currently trying to light, glow plug indicator and the pump are going, but doesn't want to light off.

[@uncoolkid666]

Good grief. Forgot how difficult my install was. The hatred is unreal. The quality is absurd. Like everything is wrong. I only even used this thing a couple of months. Plugged up, turns out the pump isn't er, pumping despite doing so merrily, so recently. I already properly disposed of the provided filter and put on a huge canister filter with a water bowl. The last time I messed with it seemed the blower motor was acting stuck This is just so much fun its incredible

[@leightondavies3127]

Great video got the same problem with the heater on my truck at least I now know what's causing the problem so be stripping mine down in morning

[@magnetron-magnetfishing4960]

if you put the exhaust paste , away from the edge of the outlet pipe , you avoid any paste being scraped into the exhaust , causing an obstructing , i think thats what happened here.

[@JayHughart]

Flagpoles from amazon maybe ebay duno but I got these out of a "return bin" and they work SUPER for ex pipe!. I put them on my van and in garage! Fits perfect onto the ex of unit, sections of bout .5 meter then the top where the ball is fit PERFECTLY on the outside of a muffler! (with two little half holes who cares!) I got all of em I could and my cats Hungry.... TBC...

[@juhajuntunen2557]

From my experience from same heater, if I use maximum pump speed, 5,4Hz it start sooting and after a while barely give any warm. And it would not start, only white smoke. If pump settings are 5.2Hz or lower then it goes on without problem. I think it does not got enough air to burner. Maybe fan speed tinkerin can help but some said that bearings will worn out quite fast if run 5000 rpm

[@scottturnbull2702]

Got me out of a right pickle this tutorial, thanks alot mate. 👍

[@PeterJavea]

I'm having this E8 problem. (White smoke, no ignition) so I will open it up The only criticism I have here is that you changed the whole burner, and not the original burner. As a technician, the reason that it ignited isn't clear. Was it because you cleaned it (probably YES). If you'd have put the original burner back in, it would have been conclusive proof that the cleaning out, by itself, did the trick.

[@darinmason2987]

At the start of the video you said that the person that sent the heater to you claimed it was new and it had never run …???.. clearly it was a very well used heater being operated by somebody who had no idea what they where doing with the settings for the burn control causing this problem of over fuelling the combustion chamber . Apart from that what a great video for all those do it your selfies .. nice job .. 😊

[@DavidMcLuckie]

Sorry, not that it had never run, but had never run properly. I don't know what it had been run on, or if something had made a nest inside. :)

[@apollo8352]

I had problems with my diesel heater and I thought it was a faulty fuel pump so I installed a new pump, after all they are cheap on ebay.... but my problem turned out to be the silly little hose clips letting air into the suction line from the fuel tank. I fixed the air leaking hose and the heater worked great for its test, but on holidays using it, it started smoking and got so bad it could not be used. Once home I removed the heater and got a repair kit I did not need....and pulled the heater apart and got maybe a cup full of oily soot from its insides.....I had been running it on low mostly so concluded it should be put on high every now and again to burn itself clean.... That is when I watched a video on just how the fuel pump size controls the air fuel mixture....and sure enough I had installed a larger pump..... I installed my original pump and were thinking I might have to pull the heater out again to clear the soot build up when I got the idea of using a 12v matteress inflatar to blow extra air into the heater combustion air intake and see if it could burn it clean, and it worked a treat....with the heater thermostat set to maximum I removed the combustion air intake filter and blew the extra air in.....and it roared and smoked like crazy but heated up and burnt itself clean..... It has been working like new again and had hours of use since.... So don't try using anything but air to feed the combustion air supply, if the heater is smoking. Of course this is no substitute for someone that knows what they are doing programming the air fuel mix in the advanced program settings of the thermostat.

[@tomthumb2815]

If you remove the glow plug , and use brake cleaner, and carburetor cleaner with straw sometimes will clean up enough to get it hot . The carbon is acting like a space shuttle heat tile. Due to faulty controller shutdown developed this carbon condition And thank you autozone

With these settings I run the heater until it gets to temperature which is. Orally about 22 degrees in my van but the temp on the heater continues to rise...I got to 34 degrees today and decided to turn off...is this because my fan isn’t cooling the heater quickly or purely because the inside of my van is continuing to get hotter?

[@anotherhonda9402]

I have a D1LC and a D1LCC, The D1LCC had a fan with worn out bearings so had a noisy fan and I think it overheated as it currently does nothing when switched on so I think the ECU has locked out. Ordered a 801 controller to diagnose it/unlock the ECU. The D1LC has a good fan, starts up has a lot of white smoke. I swapped the burn chamber/heat exchanger over and it wouldn't pump fuel. I swapped the flame sensor over and it fires but doesn't produce hot air but the exhaust gets hot and the pump and fan are running at max. Tried running on paraffin and old white diesel. during shutdown when the pump stopped and the fan speed reduced slightly hot air started being produced. It's as it the fan is cooling the heat exchanger to much. The D1LC doesn't have a magnet/hall effect sensor so the ECU doesn't seem to have a way of monitoring the fan speed. Shame it doesn't work as I want to stop using my calor gas heater in my 20ft container workshop as refill prices are getting silly.

There might also be a presure regulator in the heater. It is a round rubber disk. If it has a hole, You will get same symptoms. The presure regulator evens out the changing presure from the pump, before the fuel reach the nozzle.

Hi David love the videos , here's a good one for you , I have a Chinese 5 kw 2 months old 300 hours use now , past few weeks seems slower to light and smoke for few minutes then lights ,now the mystery is I can smell the grey smoke coming out of the blower vents , I've checked its not from the very end of exhaust outside ,I looked underneath and its leaking right near were it joins the base / manifold outlet ,I've re done the exhaust nice strong super clamp even a wee bit of paste ,but it still puffs out a tricle of grey diesel smoke which is pulled into the gap were the silicone gasket is ,the silicone gasket is also brittle and broken only 2 months old !, any ideas were this smoke could be coming from ? I re tight end exhaust clamps 3 times to check ,it wasn't them it seems nearer the very base of the alloy exhaust pipe ,can they crack ? Its bizarre,and dangerous suppose not using it obviously till fixed , I can not see any cracks in the exhaust port ,the clamp was tight on the exhaust tube no play , I think its been doing this a while but I only can smell and see it when its starting up, Starts up .. glow plug on ,pump on ,then grey smoke then maybe 2 minutes it fires up and runs ok , the smell goes away from blower vents but I guess it could still be emitting invisible gases once its running warm , any ideas I remain baffled 😀

[@DavidMcLuckie]

If your combustion gasses are mixing with the hot air you might have a leak/crack in the heater housing that seals up again once hot. Or one of the gaskets that seal the combustion chamber could have failed and is also leaking. Do you have a carbon monoxide alarm?

[@ZerHour]

@@DavidMcLuckie yes got alarm ,took heater out the black silicone seal and the fuel inlet pipe square seal are brittle and cracked ! 3 month old heater !

HELLOOOOOO! My Vavoer "8K" is a year old. Now throws ERROR 10, smokes like a Cummins, refuses to ignite. Replaced glow plug, same. Took it apart, was super clean inside, except a hard grey ash way down in the bottom of the burn chamber. Picked and 3 tbsp. of that out, looks clean as a whistle now. Soaked in a good carb cleaner, allowed to fully dry, reassembled. Still no joy. Am thinking that the catalyst screen in the burn chamber must be gone or ruined - everything else checks out right as rain. Your thoughts, please?

[@maniyan_wanagi]

Replaced screen in glow plug chamber. I'm referring to something I'd heard of another mesh screen in the belly of the actual main burn chamber, if there is such a thing. Otherwise, I am completely stumped.

Had a similar thing happen to mine kept getting EO 8 then EO10 took the exhaust pipe off because it was running OK just fitted the exhaust with paste (whoops bit too much blocked the exhaust), cleaned the exhaust then tried again with an air pump on the inlet just for a few seconds then it fired up been running OK now turned it down to 3,4 ghz.

Hi David, is the air inlet hole near the glow plug accessible for cleaning without dismantling the combustion chamber. I was wondering if by removing the glow plug and using a right angled probe to dislodge any built up grime in the air hole would work ?

[@DavidMcLuckie]

Yes, if you take out the glowplug you can poke at it with a right angled pick as you've suggested.

[@chesneyhawkes5052]

Do you think it would be possible to clean the heater by squirting brake cleaner through the tiny hole near the glow plug before it finally gives up starting ? Great videos thanks.

[@DavidMcLuckie]

Yes. Another commenter had to do a similar thing. If you can clean out the hole and remove the glowplug and blast in there with brake cleaner as well. Then fire it up and let it burn it all off.

Thanks for the great informational videos on the heaters. The burner tube on my no name "8kw" Chinese heater screws apart so you can remove and clean the metal wool and screen sleeve in the base (not referring to the little diffuser screen around the glow plug). All the others I've seen are one piece or welded. Any idea where I can get a spare metal wool sleeve?

[@DavidMcLuckie]

Interesting. That sounds like a design I haven't seen in the cheap heaters. Have you got any pictures?

[@MrHugemoth]

I do have a picture but don't know how to send it to you. Sorry for not seeing your reply for several months. I also found new mesh inserts on eBay 5 for $15 US.

Had a new machine ie spotless that only spat out white smoke and would fail to start. Was a broken glow plug the ceramic part, swapped that out and Bingo.

My one drips oil from the intake but only when it is run on a mixture of engine oil and diesel, doesn't do it when run on strait diesel, any suggestions on what may be going on, it is a new heater with the new controller like the black one in this video only it has a spanner emblem where the others have a asterisk, none of the codes work only 1234 and it gives you some strange settings.

[@markparr7224]

Ever try shooting in a good blast of brakleen into the intake while it is running to de-carbonize? Just wondering if it would actually work or not.

Hi David, have you known a pump runaway? It overdiesels and clicks at high speed. Cheers Tim.

[@DavidMcLuckie]

I haven't had one do that. That is a odd thing for it to do.

[@timevans815]

@@DavidMcLuckie Yes weird. I have ordered a motherboard which might sort it. Another heater I have still smokes a bit after I serviced it but it lights up and runs ok. Any thoughts on smoke whe running ok? Cheers Tim

Pan down for the "Safety Crocs" . . . . By the way what Bench Power Supply you got. . . ? I was stoked when you explained the "vent hole up" . . . I want to rotate my tower unit so as the exhaust comes out the side.

@@DavidMcLuckie I'm sure you used to use two in parallel for the current requirement?

[@DavidMcLuckie]

Seems to depend on the heater. That one only used 9A at startup, but I've got another now to play with that uses more than 10A.

[@nobody1841]

Did you replace the internal gasket as well? If so, was the old one cracked or anything? Thanks for the vid.

[@DavidMcLuckie]

Gasket was fine. Usually they come apart without tearing.

[@helirious]

Hi! Love your video's my man. It takes some effort to make out the dialect :), but thats ok. Did you already experiment with a catalyst in the exhaust?

[@DavidMcLuckie]

Do you mean like a catalytic converter?

[@helirious]

@@DavidMcLuckie Yes! Like from a car. It might mitigate smoke? (I've seen people do some easy tests on yt, I always thought it was difficult to get it working because of controlling rich/lean mixture. but could work apparently?? So, juuust a thought, juuuust a thought.. as Halle Berry put it once :p)

Awesome info, Helloooo from the USA

[@holeshot406]

Hi David, I’ve got an eberspacher gas ( petrol for you ) heater that’s been tested to confirm the ECU crapped out, causing the fuel to never ignite. Issue is the cost of a new ECU at $680 Canadian at last check. My question is: can a person manually power the glow plug & ignite the fuel by providing power with separate switches and wiring hooked up to the same wires in the harness ? If all that’s missing is the signal from the ECU, would it continue to run if both electrical signals were provided outside of the ECU ? Or is there anyone that can rebuild the ECU, for a reasonable price ? Thank you, Henry in Alberta, Canada.

[@DavidMcLuckie]

If it tries to run and pumps fuel but only the glowplug is missing, I'd remove the old glowplug from the heater but leave it attached to the ECU and fit another glowplug, give it 10V and see if the heater fires up. Not sure about Canada but there are a few companies in the UK that can repair the ECUs.

[@dudeleboski2692]

David, could you soak it to clean it? If so with what?

8mm self tapping screw will remove the gauze gently does it
