Evapo-Rust has been hit or miss for me. Sometimes it works great.
Other times within a day or two the part has a thin layer of rust on
it. The faq section of their website says:

... "It is important to always rinse the metal after a treatment with
Evapo-Rust. Tiny molecules of iron will still be embedded in the
Evapo-Rust solution, and these molecules must be rinsed off with water
or they will activate the re-formation of rust on the metal object."

I'm a user, not a collector. Brass brushes for the heavy stuff. Rubber
sanding blocks for the lighter stuff. Evapo-Rust for the complicated
shape stuff. Call it patina and live with it for everything else.

Thanks,
Chris
