The tannic acid dries pretty quick, but you should let the final coat dry overnight if you are going to paint the artifact afterwards.

Submersing your iron artifact for 30 seconds will be enough to complete the dehydration project.

Solvents can be dangerous if inhaled or handled, so the solvent dehydrating procedure should be conducted outside, with adequate protection, and according to the instructions given for any specific solvent used.Rust converters are not designed to remove the rust but to convert unstable corrosion into a stable, protective layer with the help of a latex-based coating.
