Kingston Brass HKVPB30MB0 is a wall-mount basin with a granite/marble top. It features a smooth glass finish and requires resealing at least once a year. To maintain its surface, it is recommended to use Stone Care's "Clean Encounters" cleaner weekly and "Counterriffic" disinfectant spray on a weekly basis. Avoid abrasive cleaners and rough cleaning pads. Use coasters under drinking glasses to prevent glass rings on the surface. Do not stand on the granite/marble top to fix overhead lights or other items.
