Clean stone surfaces with a few drops of neutral cleaner, stone soap, or a mild liquid dishwashing detergent and warm water.
Glass cleaner works well, but avoid glass cleaners that contain ammonia, such as regular Windex®. A good one to use that we have found is Glass Plus®. Most ammonia-free glass cleaners will state as such on the label.
Too much cleaner or soap may leave a film and cause streaks. If this happens, clean up excess soapy film with clear, warm water and a clean sponge or rag.
Do not use products that contain lemon, orange, citrus, vinegar or other acids on the countertop. The high acid content can dull the finish.
When we install every piece of stone we seal it with a sealer that will protect it for 1 year, and every stone should be resealed every 8-12 months.
