Evaporust won't eat metal, although it will eave an etch line if anything sticks up above it. I would have to agree with that also. Everything that i have thrown into a Evaporust pail for the past 10 years of using the product, has come out a ok. Never had any problems of "eating" any of the metal away. And i have forgotten to take things out, many times, after putting them in the pail. But the great majority of parts that i soak out are brake parts, suspension parts, engine parts, nuts and bolts. What kind of parts would people be thinking of, getting "eaten"?

Evaporust contains acid. Acid will eat rust first, but will also start to eat metals after that.
For me personally, I would have no problem at all using it on the outside of a rear end "pumpkin". Since the cast iron is so thick, it wouldn't hurt a thing. I would also soak the gears inside the pumpkin, but not leave it in the Evaporust too long (maybe an hour or two) so that I didn't eat away very much of the important metal inside the pumpkin. My 2-cents. No acid in Evaporust, from their website: BIODEGRADABLE Evapo-Rust® rust remover is safe on skin and all materials except rust! It's also biodegradable and earth-friendly. Water soluble and pH-neutral, Evapo-Rust® is non-toxic, non-corrosive, non-flammable, and contains no acids, bases, or solvents. Evapo-Rust® is simply the safest rust remover.

When he went to assemble his engine the pins slipped right through, no more press fit.
Keep in mind that rust is the corrosion of metal, if the rust is removed, the rusty part will then become smaller.

I've had some small parts in it soaking for quite some time, (months). After reading this, I want to rinse 'em off and see how they look. What do you folks recommend to rinse?

I love evaporust. Just don't let it evaporate with a part in the solution. Creates a real mess.

I have been very impressed with Evaporust’s mild affect on everything but the rust. It is pH neutral, neither acid like vinegar, or basic like lye. Moparts has a long thread on this: https://board.moparts.org/ubbthreads/ubbt...tml#Post2260350I usually have to lightly stainless steel brush the surfaces every 12 hours. I still suspect old Evaporust could be recycled by adding either strong acid (or strong base) to get the “chelated iron” to release into liquid and drop to the bottom of a container, then neutralize back to a pH of 7. Strong magnets might help do this quicker. I have not tried Evaporust in a small ultrasonic bath yet, but intend to. I also have a Tide/ Black&Decker “Buzz” brand ultrasonic probe I intend to use in combination with Evaporust in a larger tank. https://www.ebay.com/i/123165492683?chn=...195a6a0fff9bad1I bought a one gallon jug of 4:1 concentrate Safest Rust Remover but have not used it yet. I intend to pump it as a spray against the underside of a pickup and catch the drippings in a kiddie swimming pool for recycle to the pump. I bought some “Washing Soda” and intend to try Electrolosis rust removal in a plastic container using a 12 volt 1.6/2/10/50 amp battery charger.

My hardware came out great. I just cleaned 'em of with a rag and sprayed with silicone based lubricant.
