Brush Cleaning for the Gum Bichromate Process

All

Sorry for such a basic question but I have not seen this addressed in any books or articles.

For the gum bichromate process

What should you use for cleaning your hake or other types of brush after you have applied your gum-pigment/dichromate solution to your watercolor paper?

Also, if you use the brush technique for applying the gelatin and formaldehyde to size your paper, what should you use for cleaning your brush.

Thanks!
