2 hours max.
Good stuff.


Interesting that you've found it doesn't hurt finishes. According to the
Orison marketing website:

"EVAPO-RUST [is] perfect for removing weapon finishes such as Bluing,
Parkerizing, Zinc Phosphate, and Browning. Blueing and zinc phosphate
coatings (heavy zinc per MIL-DTL-16232 and light zinc per TT-C-490) can be
removed both at room temperature (@30 minutes) and 118 dergrees Fahrenheit
(@15 minutes)."

According to them, it eats up finishes (and rather quickly at that)! What
types of finishes have you tried that it didn't damage?

Sorry, I should have said it doesn't hurt good paint. Old paint is
another matter, as it took the paint of a a 1937-ish AA hobby lathe.
As for bluing, since it's basically a form or rust, it makes sense
that it would remove that.
So in this case it might not be what the OP needs.

Does electrolysis remove bluing?
