Removing Powder Coating 

.

Is there a chemical way of removing powder coating from brass without harming the brass in anyway? Is sandblasting absolutely necessary for good adhesion of powder coating to brass?

If the powder is polyester or epoxy-polyester a cold solvent stripper made from Benzyl alcohol and containing 10 g/l KOH will remove it in about 30 mins without harm. Rinse off with water, but DO NOT add water to the product. R
