[@aragrox]

Dam, that spray can needs some WD-40 sanding as well.

I've used this method with 1000 grit paper on Suntour SR Forks on two Mountain bikes. Both were black and pitted. Now 98 % perfect. Works wonders this method. Thanks for the video.

[@CyberMacGyver]

Joe N excellent to hear. Thanks for the feedback mate 👍

[@jeffreyzimmerman5152]

This really works!!! Thank you for this vid. I got a great deal on a really sweet Giant hybrid only to discover that very significant rust had been concealed by a dark colored bike grease. Thought I got hood winked and I suspect the seller also thought so. This technique worked beautifully. I used a 1000 grit and the forks are now void of all rust with no pitting detectable to the touch.

[@CyberMacGyver]

that's awesome news... im really pleased it was helpful, and easy too. thanks for the feedback and support. cheers, CM

[@henry3397]

I used liquid wrench with 1500 grit, but wow! It worked amazingly, and super fast. I thought I would be scrubbing for hours but not at all. Gonna sub to see what else you got!

[@balazserdelyi2713]

Wow I have the same problem, but I couldn't found any other video about removing the rust. Everybody said that I need a new folk. Thank you, you proved that I don't need a new.

[@CyberMacGyver]

the rust will come back eventually, but a light rub will sort that again. smear some grease into the rust areas to slow the process of re-rusting. thank you for watching and leaving feedback

[@eko653]

@@CyberMacGyver I am reworking a bike fork again, was rusty af, did the whole thing with 300, 600, 1000p, 1500p and 3000. It shines like new, but I am thinking about spraying it now with some protective spray paint? For it not to rust anymore then I would polish it again with 3000p for the smoothness.. what paint could work well and withstand the friction???

[@hessamkashani7608]

@@eko653 No paint. Just put a small bit of grease inside the upper outer seal

[@MattiLoimaranta]

Thats irony. WD-40 Rust remover covered in rust

[@CyberMacGyver]

Slege 😉👍

[@Christophe_L]

This is why you have two rust removers, otherwise how would you remove the rust if you only have only one rust remover? :D

[@DarViKo]

Slege, must be irony, iron rusts

[@offom]

I have some concerns and questions. Where does that rusty wd40 leak into? Suspension valves? Damper oil? I wish you had just prevented from dripping down.

[@hessamkashani7608]

Technically, you would be replacing the fork seals upon doing this repair.

[@motok1d]

It's literally running onto the base of the fork leg. The fork seals are above the chrome tube

[@stueydoubleyou]

Thanks for the upload I feel like dancing now

[@Gaming_live_10]

Any scratch or damage isshu ?? With polish paper ??

[@tejanpillay8245]

great! look forward to trying. would a metal polish like Autosol work better? also, why do you recommend side to side motion only? cool track by the way.. and very fitting considering the part you working on! 😏

[@CyberMacGyver]

Tejan Pillay thanks for dropping by. Autosol should work as its a fine paste, anything non corrosive is ok. The reason for circular rubbing motion; the shocks travel up an down, therefore any scratches/grooves will cause a microscopic 'leak' from the rubber seal at the top. A long scratch will funnel the oil out of the shocks and therefore a mess, eventually. You dont want any scratches from top to bottom. I should clarify this fact in the info section. Thanks for watching and commenting... cheers mate! 👍

[@LigerZero1985]

that is what i need right now! my cb1000r fork tubes have two massive rust spots, replacing them will cost me a big forture, will try this method before bringing them to local dealer to replace them

[@robertslomion4813]

Hello did you fix your fork this method ?

[@wwfww]

Sand paper isn’t going anywhere near my bike unless it’s through god tier mechanic’s hands

[@ulfrenman4012]

Interesting!! But why "Rub around the circumference and not along the length"? It seems along the length would be the natural way to go since that is the direction the dampening motion will be when using the bike.

[@CyberMacGyver]

the circumference is the orientation of the rubber seal (like a donut), if the strokes were lengthwise, microscopic scratches could leak oil and/or pressure up and out of the shock unit. also, its possible to get a tight seal if the diameter varies but not if there is an elongated scratch running down the strut. thanks for watching 🖖🏼 stay safe

[@shahzadghouse7118]

I did as instructed and it did work for me! Thank you so much! However a few dots still remain and i tried scratching em with my fingernails but it didn’t work. What did i do wrong?

[@CyberMacGyver]

if the rust flakes dont 'scratch' off, try some more spray and rub. maybe the rust has completely destroyed the chrome coating.. some grease will slow down the rust re-growth. i dont think you did anything wrong 👍🏼

[@iamjamestheiv]

Thanks man this is super helpful I have to clean up some forks on a mountain bike I just bought.

[@codedecode878]

you triggered my OCD by not getting those few spots in that tough to reach area.

[@CyberMacGyver]

codedecode 😅 you noticed... my fail. U need a bit of ocd to get good results. 👍

[@BikerStuff]

Why WD40? Why not soapy water or a light oil or anything else slippery?

[@CyberMacGyver]

'wd' was nearby and seemed like a better option compared to water. i didnt try any other fluids but suspect that oil will work just the same

[@spooktasticaparanormal]

Nice work.

[@Francesco-qy9bh]

Does this process leave any minimum scratch on the fork? Because mine is not rusty but have just a minimum sign on it so I don’t want to get it worse😅

[@jsmu1234]

i tried removing those "minimum sign" of rust using my tower and WS-40. 1) Spray WS-40 on the rust area 2) leave it for couple of minutes and then follow by 3) rubbing the tower (with some WS-40 applied on it) on the area concerns..... keep rubbing and use your finger nails too as it fasten the removal. I did it without using the sand grit paper on "none scratch rust"

[@brobinson8614]

Jesus I’d be recommending a bead of silicone (let dry) at the seal or even painters masking tape or electrical tape to stop that fine grit getting into the seal area as will over time wear it out. Carefully clean off the emery grit, and then peal the silicon or tape off afterwards.

[@Chilldude579]

Does it become rusty later on as well?

[@Ladosligese]

gonna try this with ACF50 should prob work a treat

[@gprice1978]

I'm going to try this on my bike, thank you!!!

[@sleeks9939]

Vinegar works better.

[@topnotchlion1524]

Mr. C. M. I have a Trek bicycle i used aluminium foil to get the rust of i didn't use the side to side smooth rubbing motion like you nor did i use wd40 i scratched the fork some the rust came off but scratches how badly will that affect the fork and is there anything i can do?

[@CyberMacGyver]

hi topnotch. if those scratches are anywhere near the shocks, you may lose oil and get messy eventually. but don't worry, only if they are in the path of the rubber seals when the forks are compressed. basically, you dont want to leak oil because of deep scratches. the foil method is pretty safe tho. thanks for dropping in.. cm

[@topnotchlion1524]

Cyber MacGyver thank you

[@genericcarchannel]

Just got a serious advisory for the forks leaking oil I bought a used replacement and there is slightly pitting so not quite rusted will it still work

[@CyberMacGyver]

Jason Ruckwardt pitting could be an issue if it is in the 'line of fire'..ie within the path of the shock traveling up and down. No cure for pitted shocks, a rechrome treatment costs more than a new one. Sorry for the bad news

[@genericcarchannel]

Cyber MacGyver nah its fine managed to findd replacement forks and exchanged the legs but thanks anyway

[@chizelk]

Cyber MacGyver I had a friend who used araldite to fix the pitting on my ex up 1000 forks. So there is definitely a cheap fix though tricky to get spot on.

[@609P0d]

Hi, I have a lubricated silicon carbide abrasive paper electro coated sand paper 280A is that gna work the same as p1500 or even finer? thanks!

[@CyberMacGyver]

im not sure how fine the grit is on 280a... but the finer the better. you may notice my paper was already used and slightly worn, almost as smooth as writing paper. very fine paper and plenty of lube

[@x-105strikefreedom]

can you also do that on a 2 stroke arrester? mine is rusty. thanks

[@sparklysparks77]

Hi, thanks for the video, it looks pretty legit to me. I have a question though, will this work on a fork tube with pinches (smaller than the head of a pin, not sure where those are from!) that keep messing [new] seals? I am on the third one in 6 months, btw and the seals last around 5-7 weeks before a small leak appears. My theory is, the edges of the pinches, and there are several of them on the tube, are rough and will not allow seals to continue doing their job for a long time. Pls help.

[@montanawhite5699]

I’ve done this dozens of times on my Harley and crf230l. Anything pretty much works. Crumpled up foil and water... 0000 steel wool, sandpaper... but it comes back within a month or so. How can I prevent it from coming back? I have this problem with ALL the chrome on my Harley.

[@ianmcgarrigle9510]

you cant stop it coming back ,,, the trick is to stop it happening in the first place ,

[@CyberMacGyver]

smear some grease on the forks. the reason it happens is because there's microscopic pinholes/pits in the chrome's surface. over time the holes get wet and oxidize, eventually growing back rusty and crusty. permanent fixes; you can use a chrome polish/restorer for your shiny chrome pieces. the forks may need a re-chrome to stop it from tearing your seals apart.

[@ellowlyngodson]

is sandpaper suggested???

[@adrianatienza9968]

What kind of sandpaper is that?

[@rajanikanthss]

Is that a emry sheet you are rubbing

[@CyberMacGyver]

Rajanikanth S yes it is emery, in Australia we call it 'wet n dry'. it works best as it stays flat and doesn't fall apart when soaked with wd40 👌

[@Kyle99_03]

Should work for most Dirtbike fork legs too right?

[@CyberMacGyver]

Kyle P. just as easy i reckon. Dirts have tall shocks and are flipped the other way up. Go easy and lite at first, plenty wd40. 👍

[@Kevin.L_]

Great content. Thanks.

[@theprogrammerrolandmc3039]

Why do this imagine what they are like inside the fork

[@ShiftyReaperGaming]

What grit sandpaper

[@HowTo15969]

I did this and it rusted back again in one day😕 what did I do wrong? Did I use wrong WD40?

[@CyberMacGyver]

sounds like the chrome has worn off. try smearing a thick grease. the areas used when riding should stay shiny and clean.

[@ianmcgarrigle9510]

you cant remove rust , all you have done is clean off the iron oxide the pitting in the chrome finish is still there . and sanding chrome just takes off the top layer of the surface making things worse in the long run

[@CyberMacGyver]

what's your DIY fix? $1200 to get them rechromed and machined?

[@DilbertMuc]

I agree. Sandpaper ist extremely hard (carbides) and removes the upper layers of atoms, both the porous iron oxide and also the chrome layer. Since the chrome layer is extremely thin, after this sandpaper treatment the fork will rust even stronger. Is it much better to use an abrasive material which removes rust but not the chrome layer. That's why the aluminum foil method is better. And WD40 is really weak in solving rust, better use a mild rust remover from the car shop. Check RJ The Bike Guy, he uses a weak acid (vinegar) to dissolve the porous iron oxide layer and then some scrubb, brass brush or aluminum foil to remove the stains. The chrome layer remains untouched.

[@sdqsdq6274]

why would one sand a fork stem , so risky , lol

[@abdulshaheed7638]

Bro which type rubbing paper ? Name

[@CyberMacGyver]

wet and dry paper.. Norton is my local brand. thanks for watching

All that lubricant going over to e break disc behind the fork 🤷🏼‍♂️

[@es8554]

You would’ve had the same result with using just water if you were to use sandpaper like you did

[@raymondclemetson9936]

Thank you for the simplification.

[@omkarmore6628]

Can we fix fork scratch with this method???

[@CyberMacGyver]

only shallow microscopic scratches... if they are thru the outer lining and into the underlying steel, then the rust will return or the seal will leak. try smearing dense grease after sanding, that may prevent air and water getting back in. good luck and thanks for watching 👍🏼

[@kivitropikal6755]

Just in case I want to tell you guys. If you accidently or not knowingly sprayed wd40 to your break disk don't worry. Just drive your bike in a safe place while breaking your brake. Just full brake and drive eventually all the wd40 on your disk will burn out because of friction.

[@johnnyhun1]

or just spray brake cleaner fluid on it lol...
