How to Remove Oil Base Paint From a Granite Composite Sink

Chip small paint drops carefully off the granite surface with a razor blade. For large paint spills, apply a commercial paint stripper as directed on the label. Gently remove the paint “goo” from the granite after the caustic soda or lye-based product begins to soak through, using a plastic putty knife or wooden scraping tool, suggests the Marble Institute of America.

Rinse the granite surface thoroughly with water and follow any other directions for clean up on the paint stripper’s label. Paint stripping products can stain and etch granite surfaces; re-polish the stone after removing any stains, if necessary.

Remove any staining or discoloring left behind from the oil-based paint or paint stripper using a clean damp rag and a gentle household cleanser with bleach. Rinse the sink with water.

Rub a sprinkling of marble polishing powder over the discolored surface using a damp cloth until you have eliminated the etching. Rinse the sink with water. Call a professional stone refinisher for removal of stubborn marks.
