Rust911 is by far the best product to remove rust I’ve ever seen. Great support as well!! I used this product to remove rust from a Honda four wheeler fuel tank that came from New York used as a snow plow but now resides in Texas. I had to pry the fuel cap off. Rust 911 saved me from having to buy another tank. Honda doesn’t even sell the the tank or fuel cap anymore. The fuel cap Cindy me $85 and the tank would of cost me $180. Thanks again Rust 911!!!! I’ve been a small engine mechanic for over thirty years Trust this product. It’s well worth the money!!!

Follow the directions for mixing with water. I have soaked many different tools in this product and has given me the best results. I use a bin with a lid, let tools soak with lid on. Rinse, brush, rinse and dry. I then spray mineral oil(baby oil) on the tools. Works better that WD40 and other spray oils. I am a victim of Hurricane Ian, 7’ of salt water in my garage. Thousands of dollars of tools went for a swim in salt water.

This stuff is cheaper than Evaporust so I got it for a rusty motorcycle gas tank I had. I had tried the Vinegar trick with little success due to it flash rusting in literal minutes. After that failure I got this and let it sit for about 3 days and the metal was completely clear of rust. I also didn't have to try flushing the gas tank like crazy with a garden hose or neutralizing any acids since this isn't acidic. For my MC gas tank all I had to do to rinse it out was put in about 3/4 of a gallon and swash it around for about 3-4 minutes; did it once again with another 3/4 of a gallon for another 3-4 minutes and then just filled up the tank with fresh gas. It's been about 4 months since then and my tank is still about 99.9% clear. I never put an epoxy coating in it since I've heard bad things and figured keeping the tank full of gas should be good enough. 99.9% free of rust after 4 months proves this stuff works and won't cause issues like vinegar does. I keep it in a 5 gallon bucket with a lid as well for when I need more of it. Shelf life is a year after opening.

I ordered Rust911 to see how it would perform compared to my usual go-to for rust removal, which has been Evaporust. It works nearly as well, and I say nearly because Evaporust does work a bit faster/more effective in a crunch of time. However, for the price difference, Rust911 is WAY more cost effective. This concentration just needs to be diluted with water and you're set. It's a quarter of the cost for a greater quantity of product. I'd only wish I'd tried it sooner and saved myself some money. For reference, I use this primarily for derusting old motorcycle fuel tanks and automotive parts. Great stuff! Keep the cost where its at and you've got a lifetime buyer.

I wish that I'd taken before pictures, but this product did a very good job of removing rust from several moderately rusted items that just barely fit into a 4 gallon rectangular tub. I only used 16 oz of the concentrate mixed with two gallons of water and then flipped the sides that were not submerged over after about an hour. Worked really well on the cast-iron heavy AC compressor bracket and brake pedal, and still quite good but not as great on the brake pedal bracket, made from thinner stamped steel that likely had some coating. Better results and much more cost-effective than Evaporust. I did hit all of the parts with a brass brush drill attachment first in order to not waste the chemical on stuff that could easily be removed mechanically. Very effective product that I'll buy again when I run out.

Dear Rust911, I recently purchased your product in the 5 gallon pail a few months ago. I finally had time to use it. I mixed up about half of the liquid and made up 40 gallons that I put in a drum. I put my engine block into it and took it out the next morning. Originally the block was real rusty, and now its like brand new. after that i put in a steering rack, coil springs, rotors, and some misc. truck parts. It’s still going... I recommend using this without hesitation. I still have half of a pail left, I can’t wait till the next project. Sincerely, Susan

Rust Inside a Gas Tank Can Ruin Fuel Systems

Rust flakes, sludge, and corrosion inside a fuel tank can clog filters, contaminate carburetors, damage fuel pumps, and cause poor engine performance. Rust911 helps clean internal tank rust by soaking the rusted metal surface with an acid-free rust-removing solution.

Removes Internal Rust

Ideal for cleaning rust from the inside of steel fuel tanks where brushes, sandpaper, and abrasive tools cannot reach.

Acid-Free Chemistry

Rust911 uses chelation-based rust removal rather than harsh acid attack, making it a smart option for restoration work.

Economical Concentrate

One gallon makes up to 16 gallons of working solution, giving you more usable rust remover per bottle.

Great for Vintage Projects

Use Rust911 for motorcycles, classic cars, tractors, farm equipment, and hard-to-find replacement tanks.

How to Clean a Rusty Gas Tank with Rust911

Follow the product label directions for your exact Rust911 product size and dilution. The basic process is simple: degrease, rinse, fill, soak, drain, dry, and protect.

  1. Remove the tank from the vehicle, if possible. Drain all fuel safely and work in a well-ventilated area away from sparks, flames, heaters, and ignition sources.
  2. Remove loose debris. Shake out loose rust flakes, sediment, old fuel residue, and foreign material.
  3. Degrease the tank first. Oil, varnish, fuel residue, and sludge can block rust remover from contacting the rust. Clean the tank before adding Rust911. Try Rust911 detergents or simple green.
  4. Seal tank openings. Plug petcock holes, sender holes, and filler openings using compatible temporary plugs or caps.
  5. Add mixed Rust911 solution. Fill the tank enough to contact all rusted internal surfaces. Rotate the tank periodically if a complete fill is not practical.
  6. Allow proper soak time. Light rust may clean faster. Heavy corrosion may need a longer soak. Keep the rusted metal wet with solution.
  7. Drain, rinse, and dry immediately. After rust removal, rinse the tank thoroughly and dry completely using airflow, warm air, or other safe drying methods.
  8. Protect the clean tank. Clean bare steel can flash rust. Add fuel, oil fogging, a compatible tank sealer, or other protection soon after drying.
Important: Do not use Rust911 in tanks with unknown coatings, failing tank liners, delicate plating, or mixed materials without testing first. Always verify compatibility before soaking valuable or rare tanks.

Gas Tank Rust Removal FAQs

Can Rust911 remove rust from inside a motorcycle gas tank?

Yes. Rust911 is well suited for soaking rust inside steel motorcycle gas tanks. Degrease the tank first, keep the rusted surfaces in contact with the solution, then rinse and dry thoroughly after cleaning.

Can I use Rust911 on classic car or tractor fuel tanks?

Yes. Rust911 can be used on many steel fuel tanks from classic cars, tractors, ATVs, UTVs, and small engines. Always test first if the tank has unknown coatings, sealers, or mixed materials.

Do I need to remove fuel, oil, or varnish before using Rust911?

Yes. Fuel residue, oil, sludge, and varnish can block rust remover from reaching the metal surface. Degreasing before rust removal gives better results.

Will the tank rust again after cleaning?

Bare steel can flash rust if left unprotected. After cleaning, rinse and dry the tank completely, then protect the metal with fuel, oil fogging, a compatible tank liner, or another rust-prevention method.

Is Rust911 an acid-based gas tank cleaner?

No. Rust911 is marketed as an acid-free, chelation-based rust remover.

Restore the Tank. Protect the Fuel System.

Use Rust911 16X Ultra-Concentrate to remove rust from steel gas tanks, tools, automotive parts, and restoration components without harsh acid chemistry.
