To clean rust from a motorcycle’s gas tank, follow these steps:
- Fill the tank with a sealer and swirl to create a single, even layer around the whole inside.
- Remove the old petcock and gas cap as they are likely just as worn as the old tank.
- Seal off the petcock hole by pouring in kerosene and shaking. Empty, wash, and dry the tank.
- Use fuel additives like Caswell Tank Sealer to prevent rust from forming again. After blasting out existing rust, recoat it with a good liner to prevent rusting again.
- Empty the tank, leave it outside in the sun for 3 days, pour 2 stroke oil in, and swirl around to get into every corner. When reusing, pour half a gallon of KBS Tank Sealer System.
- The KBS Tank Sealer System will stop rust and form a tough, fuel impervious coating while sealing small pinholes and weld seams.
- The safest method of chemical rust removal involves mixing vinegar and baking soda to fill or nearly fill the tank. Let the mixture sit until it bubbles up.
- Cleaning vinegar is a cheap, available, and effective method for removing rust and protecting the tank interior.
In summary, cleaning rust from a motorcycle’s gas tank requires following these steps, keeping the tank full, using fuel additives, and using a sealant. The safest method of chemical rust removal involves mixing vinegar and baking soda to fill the tank and let it bubble up.

How to keep gas tank from flash rusting after cleaning?
To remove rust, utilize Deox-C, then rinse with water and dry with a compressed or warm air gun. It is recommended that the tank be filled with petrol as soon as possible, or that Ferrosol or Atom-Mac be used to prevent flash rusting.
Can I leave rust in vinegar overnight?
To remove rust from rusty items, soak them in white vinegar for up to 24 hours, then remove them and scrub with steel wool, a scouring pad, or a wire brush. Be gentle, as this may require elbow grease. If rust spots remain, repeat the process. Clean with mild dish soap and water, then dry thoroughly.
Baking soda is effective for light rust stains and thin metal items like knives. Mix water and baking soda to form a thick paste, then spread it over the metal, ensuring rusty spots are well covered. Scrub with steel wool, a scouring pad, or a wire brush. Rinse with water and repeat if needed. Dry thoroughly.
Another cleaning hack involves using lemon juice and salt to remove rust from garden tools. Cover the rusted areas with salt and squeeze fresh lemon juice over the salt. Let the mixture sit for two hours, then use the lemon rind as a scrubber. If stubborn rust stains persist, break out the steel wool, a scouring pad, or a wire brush. Rinse off the lemon juice, salt, and rust residue, then dry the metal item thoroughly.
How to remove rust from inside a gas tank?
Chemical rust removal is a safe and effective method. Mix vinegar and baking soda to fill the tank, let it sit until it bubbles and changes color with rust particles, then rinse thoroughly. Diesel fuel is another low-risk option, as it is an abrasive and effective method. Heavy-duty chemicals can also be used in a safe dilution, but follow label instructions for diluting and handling the solution. It is important to follow timing directions to avoid leaving the chemical sitting for too long, as it can eat through the tank’s walls.
How to keep inside of gas tank from rusting?
To prevent rust in fuel tanks, it is essential to separate water and oxygen from the metal by keeping the tank full. This prevents the metal from being exposed to the air and prevents water from condensing on the submerged surface. If the tank has rust, there are two options: replacing it with a new gas tank, which can be expensive and difficult to find, or sealing it. To seal a rusty fuel tank, clean the tank, remove existing rust, and coat the inside with a sealant. KBS Coatings offers tank sealer kits for different tank sizes, which include necessary materials for cleaning, rust removal, and sealing.
How long to leave vinegar in gas tank for rust?
The rust in a fuel tank was removed by filling it with White Vinegar, covering it, and leaving it for a week. The vinegar had an immediate effect, as some leaked out and the tank was already dirty. After seven days, the vinegar was poured out and scrubbed with a nylon bristle bottle brush to remove the rusty paste. To neutralize any residue, a solution of Bicarbonate of Soda and water was used, which was 1 cup of Bicarb in a tank full of water.
The solution was left for 10 minutes before pouring out. To prevent the rust from returning, the tank should be sealed with oil, wax, or paint, depending on the item and its purpose. A safe and specific product will be chosen for the job.
Can inside of fuel tank rust?
The inside of a tank can rust, but most often, it degrades on the bottom where sludge, moisture, and water accumulate. The tank’s bottom edges at the seams are the first place to start getting holes. However, the inside can rust, and if the tank isn’t filled to the top, it collects moisture and is left exposed. Smaller tanks are made of thinner gauge metal, so they will get holes faster after they start to rust and degrade. Aboveground tanks, typically single-wall steel, are painted or coated, so the outward appearance of the tank doesn’t necessarily indicate the inside’s appearance.
How to protect the inside of a petrol tank?

Can you use a rust converter inside a gas tank?
Rust Converter is not recommended for use inside a tank, but is commonly used outside large tanks. It should be applied between 50 and 100 degrees F, with best results in direct sunlight or damp conditions. Avoid applying it below 50 degrees F. Rust Converter should not be used with leftover liquid after being exposed and used, and should not be returned to the bottle with any unused liquid.
Can you put epoxy primer over a rust converter?
Epoxy primers can be used to paint over rust converters, but the type of converter used will determine the maximum bond strength of the epoxy prime coat. The adhesive bond between the coating and the surface will determine the strength of the coating. Most rust converter manufacturers do not specify epoxy primer compatibility in their datasheets, which can make manufacturers liable. However, the end results may be weaker and fail if the wrong converter is chosen or the steelwork is not prepped after application.
There are hundreds of manufacturers of epoxy primers, making it difficult to test all of them with one product. To test the converter, run a test patch inconspicuous, test the converter with various solvents, sand, prep, and key the surface, and compare two test patches to determine if the patch with the rust converter makes a difference.
What can I use to seal a hole in a petrol tank?
This video tutorial demonstrates how to repair a leaking metal fuel tank without welding. The process involves using a tank sealant, grinder, primer, sandpaper, sandblaster, rust converter, paint, degreaser, polyurethane film, and foam vibration pads. The video was created for a 1984 BMW 733i, which was experiencing a full fuel tank. The video suggests that the issue might be due to a faulty rubber line, but after removing it, the issue was resolved. The video also includes a rust converter, paint, degreaser, polyurethane film, and foam vibration pads. This method can be applied to both plastic and metal fuel tanks.
Is it better to remove rust or use rust converter?
A rust remover is a chemical solution that dissolves and removes existing rust from a metal surface, leaving it clean and ready for further treatment. It is typically used on ferrous metals like steel, cast iron, and wrought iron, while rust converters chemically react with the rust to create a stable compound, preventing further corrosion. These products are generally safe for use on ferrous metals like steel, cast iron, and wrought iron, but can also be used on non-ferrous metals like aluminum, providing a protective coating without removing the rust.

Last night I just finished treating the gas tank of my 1997 Suzuki RF900R that has a 5.55 gallon metal tank. I’ve had my Suzuki since new but my carburetors got clogged with so much rust inside the tank. Let me tell you that, honestly, I could NOT be happier with this KBS Tank Sealer Kit product. I took my time within a 2-day time period to do it right. I followed the instructions in this article except that I gave it extra time so the RustBlast could finish etching and graying the entire interior of my tank. In my view Rustblast is simply amazing. it perfectly coats the entire tank with zinc. I poured the left-over RustBlast in a bucket full of old rusted screw driver bits and it restored them really well. I poured it back into its original bottle and keeping handy to zinc any other rusted part in the future. I consider the sealer in this kit to be perfect too. Once you stir it up really well, you get a runny sealer that reaches and immediately coats every single little crevice inside the tank. It applies a nice, even, thick coat all over without leaving any voids. The amount of sealer in this kit was just enough to coat my entire 5.55 gallon metal tank. I am now just waiting for the recommended 5 days to let the sealer completely cure before I pour gasoline back into my tank. Thank you KBS. It’s been truly a pleasure using your product.
Just to help anyone out. I did this on an 07 GSX-R . If you are doing this to a sports bike tank or anything with a large opening on the bottom for the fuel pump. I wedged a styrofoam cup in and that did provide a good watertight seal. Duct tape did not work. Taking a few spare nuts and putting them on a chain to bounce around was critical for built up gunk. Don’t toss in loose bolts unless you like fishing and cursing. Additionally on my tank a siphon was a MUST, pick up two cheap siphons. Use one for the cleaner / etch. And the other for the sealer. The curvature of the tank did not allow for adequate drainage by itself. Wait until the sealer is ready to be drained, then siphon,leaving just enough to roll around to fill in any smudges made while pumping it out. This stuff works really dam well and I hope my tips help!
Tried this product on my gas tank last night. The acid did the trick, but then to wash it out with water… water on bear metal… and then drying with forced air and heat, the inside turned back into that orange rust color again. Again… It was super clean after the acid was drained, but after following the directions further, the surface became that rust brown color. What gives?? Is the sealer really going to adhere to that??
Rust is amazing. Takes rust away with little effort. Anyone who wants to use this patients is the key. I have a xv750j virago, the tank has a enormous frame tunnel unlike the one in the article. You will need to flip the tank for serveral hours becasue of how odd shaped this tank is. Everytime i thought i got the sealer out more would just pour out. I baby sat the tank for hours. Fliping the tank as to not let the sealer pool. This is the second time i did it to this tank. The first time did not go to well. But due to another issue with the tank i needed to stripe the sealer out. Although it worked out in the end striping this odd shape tank took 2 days to clean out. Not fun at all. Patients people patients. .
Using this at the moment, pays to have at least 5L demineralised water, a wet vac and hair dryer available. At least two days to do it properly helps so handy to do it while getting over covid. Had fair amount of rust so used double strength cleaning vinegar twice with 4-5mm ball bearings and some soak time, removed plenty of rust n varnish. Rinsed multiple times with tap water and dried with hair dryer. Followed KBS instructions after that but used demineralised water to avoid flash rust. My tank doesn’t drain so wet vac is worth its weight in gold, so is duct tape and a short length of small black poly pipe. Cheers.
I have a 2013 Kawasaki Vulcan 900 Custom. KBS Klean did a great job getting the varnish/residue out of the tank so I can clearly see all the rust that needs to get cleaned out by the RustBlast. Not sure if it is related, but the duct tape did not keep the holes closed where the fuel pump and gauge would normally sit. Since the purpose of the Klean is to break down the gummy substances, this may also counteract the stickiness of the tape. I did have plastic over the holes secured by rubber bands just in case – I did have some fluid leakage that made it through both barriers on the tank underbelly. Plastic under the gas cap kept a pretty good seal.
How do you handle a Harley gas tank with fuel injection that is inside the tank attached to a fuel plate cover that is approximately 8″ x 4″ leaving a big whole at the top of the tank once the injection is removed?. Do you remove the EFI system from the top plate then screw the plate back on, then start the chemical process. I have purchased your kit and a new top plate. Just waiting on better instructions on how to proceed. Should I put the plate back on or use tape to cover the large whole? I also know that you have to protect the 12 screw hole threads that screw the top plate on and the threads of the quick release that is at the bottom of the tank and not a petcock. I’m sure there are a lot of Harley owners out there that are wondering the same things. Thank you for making a reasonably priced option to seal a tank but I really need to know is how to handle a tank other than the ones I keep seeing without EFI and the top plate
The reserve tank straw and tank sediment filter attached to the fuel tap on old Hondas fit directly inside that fuel outlet tube that you covered with tape. If that hole gets blocked by sealer then the straw and filter won’t fit in there and if the sealer is too hard to drill then you’ve ruined your tank. I don’t see how this method will not fill the outlet tube up or partially block it with sealer and cause problems when you try to screw the fuel tap back on. Do the instructions give advice on how to keep the outlet tube completely free of sealer? I’ve heard some people fill that tube with newspaper before they tape it. Those filters are a custom fit and if even a drop of the sealer blocks the hole then the filter will not fit.
I’m not sure I rinsed enough after the rust blast sequence yesterday, do you suggest I put back the stuff I took out and give it another cycle or just let it dry off a little longer to see if flash rust develops. I used an air gun and heater to dry it out but there’s a few water stains. It’s completely rust free inside and no flash rust as yet
I ordered this kit a while back and go finally got to use it. I took a peek inside the tank after the cleaner and I saw a bunch of rust. I used the rust blast and afterwards noticed it was all gone. Nice. I let it sit so it could dry after I rinsed it out. I figured I’d do it at night and let it just drain overnight but when I checked my tank (same day) there was flash rust all inside the tank. is this normal? now I’m hesitant to seal the tank with rust in it again, albeit not as much rust as before. suggestions?
Question. My “mechanic used some one step crap on my aftermarket peanut tank. right now the gas is evaporating and draining because the sealer he used is dissolving inside the tank and mixing with the gas. Can I still use this to clean and reseal the tank? Also there is a hole around the petcock ring. Should I seal it with some weld stuff before re sealing? thanks!
