Rust Remover Dissolver, 16-Ounce Bottle

I messed up and forgot to take a before picture so there is no use posting an after. I'll just confirm that this works faster than I assumed. I used it to restore a gas tank on my 1995 bmw 318i that was loaded with rust. I assumed I would need to leave it over night but in a couple hours I took it out to check it and the job was completely done. Also, there was a delivery issue and the owner of this business gets 5 🌟 as well. Responds the same day within the same hour. This product and company is worth your try. They did not disappoint...not in one area.

Fantastic product, nothing works quite as well on large items. Aggressively dry the product after you soak in very hot weather, or use fish tank heaters, and paint ASAP. Items look like new, easy to use, other than setting up a soak tank.

Trying to get an antique car back to running condition, and the gas tank had lots of rust inside. I got rid of the old gas and washed it out as best I good, but there was still lots of rust. Since this makes enough to fill the tank, I thought I'd give it a try. The key I found is that cold water won't work. I filled it up, but after 12 hours, not much had happened. Recommendations were to warm it up a little, so I put a 500 watt halogen work light next to the tank. Once the solution warmed up, it did wonders! Two days later, the solution had turned black as coffee and I couldn't even see the bottom of the tank anymore. Once I got the solution out, all I can say is WOW! It cleaned up the rust beautifully on a 77 year old gas tank. The sender was sitting in it, and the tank was as rusty as the sender. The bottom of the sender is pretty much how well the tank cleaned up.

Rust 911 is inexpensive, safe to use, and kills rust, as claimed. It does NOT remove paint, primer, or body filler, but the manufacturer never claimed it does so. The parts to be derusted must be thoroughly stripped of paint before treatment with Rust 911, which can be a lot of work with today's wimpy paint stripper liquids. After treatment, the rust is transformed to a black film that must be brushed from the metal; I've found scrubbing with a stainless steel toothbrush works well. To loosen the film in hidden areas, like behind brackets, I pour a tablespoonful of steel BBs into the hidden area, tape off the holes, and vigorously shake the part. Then I remove the tape, pour out the BBs, and dunk the part back into the Rust 911 to flush the loosened particles. Several repeats of this procedure does a pretty good job removing rust from the hidden areas - slick! Even the non-rusted areas of the metal will have dark stains after treatment with Rust 911; they must also be scrubbed or sanded off. Then I rinse the metal with clear water and wipe it with phosphoric acid (metal prep) to prevent re-rusting. I also noticed if the part to be derusted is too big to be completely submerged, Rust 911 will etch a shallow groove into the part right at the waterline, which was a bit of a surprise. Overall, a good tool, but not magic.

We have been using this product for over 1 year for our business, and it works great! Thank you Mr. Phillips for your product. A1

Removes rust as described. It WILL remove "Light Surface Rust" in 30-60 minutes, but most of the rust I'm battling takes longer. On heavy issues, I've left for quite some time, including an occasional brushing and rinsing. While removal of rust will mean some material is being removed, I have not found that the product damages the remaining surface. It doesn't even remove the paint unless there was rust between the metal and the paint already. I'm not seeing it remove 'magic marker' as a general rule. It finally gives up its rust removal qualities with time, but you can use it for multiple soakings on multiple parts. It says it can be poured down drain and it doesn't burn skin (albeit I still rinse skin if contact). If you need multiple gallons of the solution, this format is the product to use as you're not paying for the water and extra packaging/shipping. Also note that you just use the amount stated as 'adding extra' does not increase effectiveness. Just wish i had huge container to dip extra large parts. Highly recommend. Will re-order.

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.

The bottom shelf of my steel (tested with a magnet) medicine cabinet had rusted badly, so I ground out as much of the rust as I could and attempted to use Rust911 to deal with the bits I couldn't get at with my grinder. I built a dam to contain the solution, mixed it up according to the directions, poured it in, and waited for two days, after which I swabbed up the liquid with rags. The result: nothing. The rust was still there, essentially unchanged (maybe a little worse after 48 hours underwater). The Rust911 has no odor, no color, no perceptible texture—I'm left with the uneasy feeling that I paid $45 for a little jug of water. UPDATE: I tried this product again, this time on some rusted steel hinges. In the photo you can see the result of soaking for FIVE days in properly-mixed Rust911. The orange smears on the paper towel are (spoiler alert!) rust. Learn from my mistake and don't waste your $$$ on this bogus crap!

It works very good
