Quote: One thing to watch out for (in addition to safety!) is "hydrogen embitttlement". The acid leaves hydrogen in the metal which reduces strength, especially with repeated cyclic loading. Baking the part afterwards can get the hydrogen out... which is what a good plating house will do.
Slower methods like de-greaser, pressure wash, wire wheel do not introduce hydrogen. Hot tank is good for suspension parts also. Hot tank followed by abrasive blast is really nice.
