Q. Do you have a product that will remove tannin stains from porcelain?
A. Sorry to hear about your stain. Thanks for contacting us. Don't delay your attempts at stain removal at all, because time is of the essence. A tannin stain that deeply penetrates can be nearly impossible to remove and can cause etching. Pour 35% strength hydrogen peroxide and a few drops of ammonia directly on the stain and leave it there until bubbling stops. Do not use ammonia by itself, because it can actually cause the stain to set in permanently. If the stain persists, apply a poultice. Your poultice ingredients will be a dry ingredient like poultice powder, diatomaceous earth, or flour mix with 35% hydrogen peroxide, which you can find at a beauty supply store. If the stain persists, you can try poulticing with a dry ingredient and mineral spirits. I you have need of professional help, contact us to find one in your area.
