Giani says to only use mild dish soap and water or a gentle window cleaner. You can remove stubborn stains with rubbing alcohol or nail polish remover (acetone) and a paper towel. Giani's instructions also state, "Never use harsh chemicals such as bleach, household cleaners, Magic Eraser, Pine-Sol, disinfectant wipes, or any abrasives such as Comet or Soft Scrub. Do not use polishes or granite cleaners. Even diluted solutions of a cleaner and water will wear down the durability of the topcoat over time. Never use harsh natural cleaners such as vinegar, rubbing alcohol, hand sanitizers, air freshener oils, or essential oils. Never use scratch pads."
