Removing Fuel Tank Rust With A Chain And Vinegar AMAZING RESULTS!

Continuing on the Honda CB750 chopper project I am removing the fuel tank rust using a chain and vinegar with amazing results! This tank was really bad with lots of old varnished fuel in the tank that turned into a flaky crud that was clinging to the bare metal sections within the tank. I started out using some chain to break up the larger chunks and get us 75% of the way there. I eventually had to use drywall screws to get the last stubborn areas of the varnish off but that worked great.

Tank cleaned, no leaks and preserved the paint. That’s a big win.

[@BrickHouseBuilds]

Was a total success 🤘

[@RogerEcks]

I had to restore a tank from a vintage Vespa we shipped from Italy. I dumped in about two pounds of screws, nuts and bolts. Then I wrapped the tank in several moving blankets and put in the the clothes dryer with no heat. After a couple of hours it was polished clean.

[@richardbalmaine8048]

I converted a cheap concrete mixer to agitate bits of chain and soapy water in the tank, I loved watching it with a beer in hand 😊

[@BrickHouseBuilds]

Yeah a concrete mixer is on thr list for sure

[@glenpaul3606]

The 1979 CB750 I restored had a gas tank full of rust. I used chains and solvent to clean out the heavy rust and flakes. Then I used Ospho to neutralize all the rust. Lastly cleaned it out with some gasoline to flush. It came out good. Ospho is amazing stuff. It turns iron oxide into iron phosphate which is inert. The rust was gone and never came back.

[@linzimumford3829]

Damn, that tank takes me back, my old GS1000 had a paint job just like it back in the 80s. Love it.

[@cobbleup]

As an older rider I have to find a less athletic method . The shaking chain method works great for those with the power of youth. What works for me is to jack up the rear of any car, truck, tractor or other vehicle and bungee the tank to the wheel, start the engine, and while in bottom gear just let the tank roll over and over for a half hour at a time until the chain or whatever medium I’m using has done its job the let it roll with the vinegar in it until it has done its job. Even leaving the chain in along with the vinegar will work too. The last tank I did had pin holes along the bottom along the pinch weld. Removed the paint in that area, used a blunt punch to create divots into the pinholes, the filled the divots with JB WELD ORIGINAL, it seals perfectly! Never have had issues with the jb weld ORIGINAL method. THE CLEAR 2 part epoxy not so much. I Don’t recommend it. All the best 🤠.

[@BrickHouseBuilds]

The red cx tank I showed before that I stripped developed holes as well. Needed a liner

I had my rusted tank filled up completely with cleaning vinegar and left it for 24 hours. Worked really well. And did all the things you did of course.

[@warmblood58]

many years ago I used some old brass keys for a BMW motorcycle tank and shook vigorously with vinegar - suddenly a key tip poked through the bottom of my tank! From that day forward, I only use vinegar and fairly light rounded chain, no sharp anything, - I often rinse and use Ospho to prevent flashing and then add two stroke mix as you did. I have never failed yet to bring back a tank from near rusty death -nice vid!

[@BrickHouseBuilds]

Oh man that would suck! I have had some very thin tanks that developed holes

[@FilosophicalPharmer]

Bought a ‘99 Ducati 900SS long ago. Previous owner poured tank liner in tank without removing *anything*, including the mesh prefilter and the fuel pump. The bike ran great until it warmed up. The guy he sold to took it to local Ducati dealership who said it needed an ECU! He sold bike to me without telling me any of this. Learned about bike after providing Duc shop the VIN. Sued him even after I signed “As-Is” statement. Why? Because he did not disclose condition. Long story longer … guy didn’t show up to court, I testified, default judgement to me and then, “It is clear to me that the seller did not represent the item accurately. Therefore, I am doubling judgment in plaintiff’s favor.” All this headache because someone installed tank liner solution incorrectly. So who is to blame?!? Italians, of course! 😂😂😂

[@jamesthurber8807]

Thanks for detailed how to. Birds knew the storm was coming. Mean golf ball hail beat up your nice blue truck. Dang

[@Errol.C-nz]

​@BrickHouseBuilds a process I use for restorations.. soak with a strong caustic solution seems to soft the oxide bond but main focus to remove water resisting oils.. the acid I use is Oxalic.. it's used by dry cleaners & wood workers to remove metallic stains in clothes & wood g available from paint & woodwork suppliers & commercial cleaning suppliers.. it doesn't seem to harm them.. at all.. & I've not had any adverse effects handling the solution with bare hands other than it stings cuts.. Oxalic acid doesn't attack the inlaying bare steel either.. at least for a few days soaking dependent on strength I would think.. I've found an enhancing visual effect by scrubbing items with a stainless steel wire brush or stainless pot mit/scouring pad.. in the solution.. there seems to be a molecular exchange that deposits I think chromium to the base steel.. it brightens it quite noticeably with a minute or so right in front of your eyes.. AFTER.. the rust/oxide has been dissolved.. the solution goes green & remains effective for further jobs for several uses & a yellow partical sediment settles in the solution.. I drain off the usable green solution for further use & discard the yellow sediment.. until it starts turning brown at which point its lost all effect.. I sometimes finish with a phosphoric acid stainless wire brush scrub.. seems a little less susceptible to rerusting tools etc.. lookup phosphatising steel (gunsmithing).. cheers 🇳🇿🇳🇿 NZ 👌👍

[@ericd7532]

I'd rather find the weak spot like you did than riding down the road with a tank full of gas that starts dripping

[@S2NAZ]

This was really explained well BJ 👍🏻 I remember restoring my buddy’s 77 KZ1000 and that tank had so much rust inside 😳 I used pea gravel to knock around the innards with some kind of rust removing liquid I bought, it was a long time ago. Took me forever 😂 You have this down to a science. See you next week 👋🏻

Great video and nicely demonstrated, what a massive difference in the tank, and what i really liked was that the products that cleaned it are what most people have in their home, it's the first time that i have seen a tank getting cleaned and it now makes it less daunting to try it myself. Really nice down to earth guy doing the video, thankyou.

Perfect timing! Now moving on from the Nighthawk ~ (not started yet). So yea. The 01 600 Bandit is well ~ yuck! Petcock needs a rebuild. I think you have another electrolysis video but this is very user friendly. Thanks again! Perfect for me right now. Oh yea. Someone says "Ospho?" Not so much about the 'clothes dryer' method. Whoo wee. Thanks again, and again, and again.

Nice job. I always put about 50ml of blue smoke oil in a full tank before a long ride. Wouldn't foul the plugs but did put a soot coating in the mufflers. Stopped worrying about rotting out with rust.

i landed here from a F9 Dr650 video; first 10 seconds on your channel and found this piece of art...rebuilding a Suzuki marauder and the fuel tank is crusty AF. thanks for all

[@BrickHouseBuilds]

Heck yeah man! You should find lots of stuff on my page so enjoy!

[@JoshA86]

Yes...baking soda is a critical step lol. Bike project i picked up last year the owner knew the tank was a little rusty so he threw vinegar in it while working on the bike and then it sat for a year. Needless to say worst rust ever. Took weeks of on and off cleaning it out. Even did your electrolysis method. I still need to seal it up for a few pinholes that popped up. I got the POR15 kit but you and a few friends of mine have recommended the Caswell, so rethinking it. I will say the POR15 degreaser did VERY well on taking out the dirt and old varnish. From what I read its about the same as a heavy duty marine cleaner. Might be worth trying next time. Excellent video as always!

[@BrickHouseBuilds]

Oh that would be the worst by leaving it in there!!

[@timrachelmortenson6821]

Thank you. This is the 4th video I watched about cleaning a gas tank. Only 2 mention neutralizing the vinegar. Looks like I have to start over on my 1985 Yamaha. I will find some muscle for the shaking, though.

[@scottcates]

My zg1000 tank is 7.5 gallons so I ended up hanging the rear end from its bolt-on bracket -- imagine a trophy fish hanging from the tail. Then I hoisted it up my carport rafter with a ratchet strap to about belt height. I had already partially filled the tank with my choice of cleaners, such as vinegar, citric acid, oxalic acid, phosphoric acid, bolts, water rinses, etc. Then I picked up the other half of the tank and methodically pushed and rocked the tank to scour the inside of the tank with all the abrasives I could cram inside, like nuts, bolts, screws, and the acid tongue of my mother-in-law. It was much easier to hold up the tank and be 100% thorough this way. Hope that helps anyone. P.S. 90% Alcohol (pick your flavor) works well as a final rinse, followed by a hair dryer to elminate flash rusting.

Simple wire brush wheel on a drill will clean up the filler neck 100%. Small wire wheel on Dremel flex shaft (porting flex shaft) will finish those leftover spots of rust. Run a spoon of two stroke oil in the fuel tank will keep it generally rust free while using it. But it will need lining.

[@BrickHouseBuilds]

No lining needed on this one fortunately

Vinegar, a brass chain with very small links, gets into all the tiny crevices better.

[@johnsalvi9073]

I’d done that, and after I cleaned it out I treated it with Kreem Fuel Tank Liner. I first got a gallon of mercuric acid from a swimming pool dealer. This was to remove the rust. You still get rust flashing when it dries out. Then you treat it with Kreem.

[@BrickHouseBuilds]

Yeah I'm not a fan of either of those methods personally. I've seen too many failed kreem and red kote liners. I avoid muriatic acid when possible

[@user-gn7cm6db2d]

Good job deffi works.

[@techo61]

Try Apple Cider Vinegar, its much stronger than white vinegar, doesnt harm the paint and is only a few bob more expensive. I also used a kilo of steel gunshot from a gunshop. It's smaller that tech screws and easily removed with a magnet. My result was perfectly rust free base metal and the gunshot was so small it got deep into the seam welds. Of course i had to use baking soda immediately just as you did to stop the flash rust. It's now been 21 years since I did my ZL1000 tank and it's still like new today.

[@BrickHouseBuilds]

This is 30% concentrate vinegar. Stronger than those others

[@banditnev]

Add a cap full of 2 stroke oil to a full tank will help too.

[@leandroleon7221]

vinegar+rocks (chain) +shake= great! when it is dry off put some oil and keep it of rust again

[@daveco1270]

II wonder what Bruce is up to now. He was painting tanks back in 1980. Hopefully he's still around and living his best life. I'm scared of vinegar because the one time I tried it the tank looked great... until after I did the rinse, then this thick rusty corrosion showed up. I did the whole baking soda step, but maybe I didn't use enough. You didn't seem to get much flash rusting. Evaporust works well, you just have to let it sit over night. And it's not as corrosive.

[@BrickHouseBuilds]

Thats why I prefer electrolysis. Much more stable

[@jimclarke1108]

Exactly what E10 does to every fuel system if left for a while

[@BrickHouseBuilds]

Nasty stuff for sure

[@jagitmax]

You should try the vinegar along with about 15 , 3/8" coarse thread steel bolts , the bolts have enough weight and sharp edges to scrape anything loose on the surface , your screw method is similar but the weight of the bolts is what really gets the job done , dry it out with a heat gun and the result is like new steel , have your tank sealing coating ready to go , but dont wait to coat the inside or you will get the flash rust on the fresh surface.

[@BrickHouseBuilds]

I'm my last one everyone said try drywall screws and not to use a heat gun lol. I know there are 10,000,000 ways to skin a cat. This worked great. Maybe I'll make another video in the future of another method to go with my other ones

Chain is smooth and rounded, not the best choice. A jar full of bolts works best because of all the sharp edges and threads. They are also smaller and will get in crevices better. Make sure to use steel bolts only because sometimes the last couple of bolts are harder to get out and you use a magnet on a stick to fish them out.

[@BrickHouseBuilds]

Sorry about your nice new truck, looks like you need a carport.

[@BrickHouseBuilds]

[@RichPober]

You touch up the small areas of rust with Phosphoric Acid, which is the active ingredient of Jenolite. Get a gallon of 99.9% Phosphoric Acid, as it is relatively cheap. You can either use the acid neat for heavy rust or dilute it to 50% or 33% concentration with tap water. Brush it on with an acid brush (Nylon brushes tend to dissolve slowly, but will last for a few jobs). Let the acid dry out and it will convert the rust to a black ferrous phosphate layer, which can then be abraded of with a wire brush.

[@BrickHouseBuilds]

Can't wire brush the inside of the tank though

[@RichPober]

@@BrickHouseBuilds You can wire brush the inside of the filler neck and cap, which were still left rusty after the vinegar treatment. The rest of than can only be cleaned as you did it - with loose screws.

[@keithagn]

Great job! I had a thought; the pressure build up from the baking soda and water could you do something like that to pop out dents from a tank? Or would that be too unstable/unpredictable? Take care, and Regards from Canada 🇨🇦

To me that's too unstable as you have no control.

I have a 2008 Triumph Bonnie that sat for a few years so am now cleaning the tank. It’s in good shape, just need to get the varnish and little bit of rust out.

Thanks in advance!!! And great videos!

[@BrickHouseBuilds]

@meredithjohnson7145 if there are no holes and the metal is good, do not use a sealer. A sealer is more of a last resort. Keeping fuel in the tank and even adding a tiny bit of oil to the fuel can keep rust away. It's when they sit empty that they rust
