Clean the countertop daily with a soft white cloth and a neutral cleaner or household detergent such as Dawn. Household cleaning products like dish detergent, Windex, Lysol Disinfectant, or 409 can be used, but may leave a film. A solution of vinegar and water works great to remove streaking, smudges, and body oil.
Important note: a sealer doesn’t make the stone stain-proof. It provides an extra barrier of protection between your stone and whatever touches it, which gives you extra time to clean up whatever you do spill on the countertop. Acidic foods are the worst offenders. We just wipe up a spill — no matter what it is — with a wet sponge right away, and our countertops look great.
That said, there are steps you can take to help protect your marble countertops from damage. Use caution when working with acidic products, like tomatoes, citrus fruits, juices, alcohol, and vinegar. Clean up spills as soon as you can with a soft cloth or sponge. Use trivets, cutting boards, and coasters religiously. Clean your countertops on a daily basis using a mild soap or stone cleaner. Re-seal your marble countertops regularly, and always follow the instructions on the label.
