Removing lacquer on old copper molds


(1998)

I need a product that will remove remaining lacquer on some old copper molds. I don't care if it reduces future tarnish. Any ideas?

Dear inquirer:

If the items are small enough, use your largest pot and fill with water and dissolve about 1/2 cup or more of baking soda [linked by editor to product info at Amazon] or more if you like. Bring the water to a boil. Then submerge the item (if space only allow put in 1/2 the item) until the lacquer is dissolved. Repeat on the other part that has not been submerged. You will know when it is off when you see the water get a film (about 15-30 minutes, sometimes longer). I have had great success with this and it costs pennies. You will then have to use a polish and then you can reapply a lacquer spray, if you desire.

Hello, Jean. You can also try a spot of nail polish remover. Brass lacquer is soluble in Acetone [linked by editor to product info at Amazon], the principal ingredient in nail polish remover. Don't combine the new methods simultaneously, however, as acetone is flammable.
