Another thing to consider is that ANY acid based rust remover ALSO removes the metal itself, at the very least you'll end up with an acid etched surface. Consider this if you are trying to preserve any of the original part surface appaearance. If the surface is a concern stick with a product like Evap-O-Rust that destroys rust and leaves all other materials (metal, paint, etc, metal finishes, etc.) 100% intact.

I have actually have tried the solution on painted items and it did leave the paint intact and glossy!

Obviously for some heavily corroded or rust covered parts the surface won't matter and the acid approach is a valid choice, but my comments on more delicate surfaces are not simply "Another Opinion" it's verifiable fact.

Acids are corrosive to most metals and many other materials, not just rust. You may have had an example of one paint that was not affected, but you can't say that accross the board it won't harm paint.

Products like Evap-O-Rust do not harm ANYTHING but the rust itself.

.....And no, I don't work for Evap-O-Rust

Actually your mistaking on this! the ph value of evaporust is 6 they claim 6-7.1 @ 1%
anything below a 7 is infact a acid
I am sure if we measure vinegar @ 1% it will be alot higher than a 3-4 on the ph scale!

It is infact a weaker acid "maybe" but still an acid!! Some examples of weak acids are acetic acid (found in vinegar), carbonic acid, hydrofluoric acid, and formic acid. evapo-rust although they claim they are not a acid my guess is if you take their straight solution and measured the it would be infact a acid! and not a base! I like how they measure it at 1%

Each works in it's own way and his advantages/disadvantages. If I had to pick a favorite, I think it would be evaporust, but there are also a lot of parts where the cheap easy acid solution would be a viable alternative.

BTW, for those who want to see just what the difference is between Evap-O-Rust and the Home brewed V/C/S mix concerning the acids effect on good metal (and not just the rust), put a small sample of each fluid in a jar. Add a few pennies to each, and toss in another item made of clean raw steel, results will vary with the proximity of the steel parts & the pennies, the effect will be more dramtic if they are touching. Let it sit overnight and have a close look at the pennies and steel parts, post your results here.
