Evapo-Rust ER012 Super Safe – 128 oz., Non Toxic Rust Remover for Auto Parts, Hardware, Antiques | Rust Removers and Chemicals

This stuff is the bomb! Re-usable until it isnt. I know, that sounds weird. I had a 3.5 gallon bucket that lasted for about 5 years and got many, many, uses out of it. Eventually the liquid becomes saturated with particulates from items that were not necessarily cleaned well. This material eventually builds up in the solution. Because of the way it works, chemical chelation, I imagine the solution eventually absorbs enough oxidized iron that it will stop working. When it no longer works, the product is bio-safe so it may be dumped down the drain (so long as it is not full of other automotive chemicals such as anti-freeze, oil, etc.). Rinse out the 3.5 gallon bucket and refill with fresh product from the 1 gallon jugs. Just make sure you clean as much gunk, grease, oil, residue, etc. off your piece before you soak it. This will keep your solution usable for a LONG time.

Used on my motorcycle tank. Looks like it cleaned it out nicely. I let it sit full for several days. Ill be soaking various parts in it along the rebuild. Obviously, it doesnt remove pitting caused by rust and restore it to new. But its all clean steel in the tank now and no worries about rust flakes in my carbs. Had to fill the tank with gravel to take up some space so I could use a gallon less. Seems everything needs to be completely submerged and soaking for a few days to do the job right. Just sloshing it around occassionally to hit all areas wasnt doing it. After all submerged, came out great.

What ever the formula is for this stuff, it saved two iron, 6 inch c-clamps that had been sitting outside on a fence post for over 5 years. The clamp was frozen where the screw part wouldnt budge and thick with rust. I thought it would be a good test for this product and to my surprise, it worked. I left it submerged in the liquid for 3 days and the color changed to pitch black. I had to heat the joining part where the threads go thru but it loosened up and with some oil, was as good as new.

I inherited a bunch of rusty tools and wanted to see if I could bring them back to life. This stuff really surprised me. As described, it didnt bother painted or plastic areas at all. It also impressively removed rust, with a nice, water rinsing liquid. Most of my stuff was surface rusted, so no deep ragged holes were uncovered. Still, chromed wrenches that had substantial rust cleaned up very nicely. Some of the tools had threaded adjusters which were frozen in place. After treatment (and a little oil) they all cleaned up and worked smoothly. Note that it says you may need to soak things overnight - this was quite true. It doesnt work fast, but it seemed to help when I would pull the rusted stuff out and scrub it a bit with wire or plastic brushes, then re-soak. One caveat: a common tool surface treatment is something called black oxide, an oxide which prevents red rust, especially if you oil it lightly. This rust remover seems to remove black oxide as well as rust. For me, this wasnt a concern. as I just sprayed everything with WD40. I expect theyll stay oile denough for me to use them with little fear of rusting.

I really like this stuff. It’s works well for light to moderate rust and it’s doesnt irritate your skin. It’s also non toxic which is great if you have children or pets around the house. I wish I had sprung for the 5 gallon bucket with the strainer in it. It is a lot more convenient and allows bigger items to be dipped and soaked. I am currently removing rust from an old Tonka Truck that has been disassembled. After the parts are treated and cleaned I will prime them with rust encapsulater primer and then paint the final color. No product will restore damaged metal so if there is pitting on the metal it will still be pitted when the rust is gone. I highly recommend the product.

So I had an engine block that had significant rust buildup in the water jackets. So much that it caused the engine to run way hot. This was a 1953 L6. So I read that this product would do the job of de-scalling the engine and eliminate rust. So I added the 128oz bottle to the engine and topped off with water. Ran the engine on and off about a dozen times over a couple day span. Then let sit for a week in the engine. Went to drain the block and the solution came out just slightly brown. I was expecting it to be black, which the label says happens when it does its job. So Im not sure if I deployed the product correctly or if it just didnt work for me. Would be willing to give it another go though.

Yowza! 24 hours and these are looking almost new after 2 years in a damp garage. I wish I had taken a before pic for reference, but almost all of the tools pictured had a rusty haze with some being completely rusted over. Clean excess oils off beforehand with Dawn detergent. Soak, rinse, dry, WD-40, and this was the result. The leftover solution can be saved and re-used, too! Outstanding!

As advertised! Toughest part is getting enough to submerge the item. But once that is done just wait and the item will come out rust free.

Rust removal isnt foreign to me. In the garage I have vinegar, phosphoric acid, Navel Jelly, and now this. Any of the acids work well, but even doing a final bath with baking soda still can leave traces and on highly stressed parts the hydrogen embrittlement can cause structural failure down the road. This works very well and will be my first choice for many parts. Vinegar is still cheaper and useful for some things, but this product has a new home.

This product does remove rust when fully submerged, but it takes a long time. I had to soak some old bolts for about 2 days to remove the vast majority of rust. Once the fluid takes on rust, it is basically useless, so I dont think it is fully reusable like they claim. If you have small parts you can fully submerge, I would recommend it, but for on-the-car stuff, this isnt going to be the best option.
