Rated 5.0 out of 5.0 by wooddude This product stripped an old tool of all rust within a few hours and afterwards the liquid was still rather clean and can be re-used so I poured it right back in the container for the next project. The nice thing about this product is that it had no odor, no fumes and while I wore gloves it was clear that the formula wasn't dangerously caustic to the touch. See image (before I soaked the hand plane) for a good idea on a vessel for the soaking that I put together.

Rated 5.0 out of 5.0 by Bucko Excellent, Easy to Use Product
I've used this product several times. It was especially useful as a bath to which I've added a very large number of rusty tools. Overnight it will de-rust lightly rusted tools, 24 hours seems to be effective in eliminating most rust from heavily rusted tools. Also, it leaves a coating on the tools, which hopefully will eliminate or reduce the possibilty of recurring rust. Also, it can be be used at least twice before its effectiveness diminishes. Even though it's fairly expensive ( $25), it represents excellent value. It also apparently comes in a large size, which lowers the cost a few dollars. I highly recommend this product.

Rated 5.0 out of 5.0 by HIGHBARR AMAZING PRODUCT
I WAS VERY SKEPTICAL ABOUT THIS PRODUCT, BUT GAVE IT A TRY AND FOUND IT WORKS GREAT JUST AS IT CLAIMS. IT SEEMS A BIT EXPENSIVE BUT WORTH IT IF YOU HAVE RUST YOU CAN'T GET TO. IT TAKES SOME TIME TO EAT THE RUST BUT AGAIN WORTH THE WAIT. A SLIGHT DOWN SIDE IS THAT THE PART NEEDS TO BE CLEAN OF ANY OIL OR DIRT BECAUSE THIS PRODUCT IS WATER BASED, HOWEVER THAT ALSO MAKES IT NOT EASY TO CLEAN UP AND NOT HARMFUL TO ANYTHING BUT THE RUST. I WOULD RECOMMEND TO SEAL THE PART SOON AFTER THE RUST IS REMOVED BECAUSE IT WILL RETURN TO THE PART QUICKLY.

I used the rust remover on a severally rusted motorcycle fuel tank. After letting it sit over night, the inside of the tank looked new

I didn't think this product would work as advertised, but it did. I removed surface rust from some shafts and some deep rust from some electric motor housing parts. Highly recommended.

Rated 4.0 out of 5.0 by Speedviktm Don't use this if you're in a hurry, but it does work.
If you're in a hurry, use Naval Jelly. If you've got 24 hours to let this stuff do it's job, it works well. Follow the directions: Clean off surface rust, wire brush works well. You don't have to be perfect, just get the loose stuff off. Soak. Rinse. Wire wheels/brushes on a drill will get the rest after that and you'll end up with bright shiny metal.

Rated 3.0 out of 5.0 by Dan It works....slowly
This is a safer alternative to Naval Jelly and similar phosphoric acid-based rust dissolving products. I believe its active ingredient may be ammonium citrate, as I had made something similar when I had access to laboratory chemicals in school. It works rather more slowly that acid-based formulations, so a larger rusty item should be bagged or well covered to minimize evaporation. I thought the price of about $25 for a gallon of the working solution was too high considering that is just a solution of a simple chemical compound in water. In that respect I think it's not very competitive with phosphoric acid products that give a similar end result more quickly and cheaply, and provide a residual phosphate coating with modest rust preventive properties, in addition to etching the surface for improved paint adhesion.
