Tenax Etch and Water Mark Remover
The Tenax Etch and Water Mark Remover is a polishing compound designed to remove etch marks, water marks, water rings, dull spots, and even light scratches on marble, travertine, limestone, alabaster and onyx stone. Simply apply a spoon full of TeEtch over the etch or water mark. Then, using a rag, rub the TeEtch over the blemish by hand. Wait 2-3 minutes and the etch or water mark will be mechanically removed and re-polished back to its original look.
