Porcelain sinks are durable, but a surface scratch can occur. Left untreated, the scratch collects dirt, leaving a dark, spidery mark. The dirt becomes difficult to remove as it digs deeper into the scratch. Bacteria may also become trapped in the scratch where disinfectants cannot reach. Remove the scratch to restore beauty to the porcelain sink and remove hidden bacteria.

  1. 1

    Spray the porcelain sink with a bathroom cleaner. Wipe the sink clean with a damp sponge, removing as much dirt inside the scratch as possible. Rinse the sink with warm water and the sponge, then dry with a soft cloth.

  2. 2

    Wet a pumice stone and fill the sink with warm water. Rub the stone gently back and forth over the scratch. After two to three passes with the stone, inspect the scratch or feel it with your finger. If the scratch remains, continuing rubbing with the pumice stone and examine the scratch after two to three passes.

  3. 3

    Drain the water from the sink. Rinse the sink with the sponge and warm water. Dry it with a clean cloth.

Tips and warnings

  • Keep the pumice stone wet at all times when rubbing the scratches.
