Cleaning Your Granite Countertops Every Day and Before Sealing

Step 1: Pour denatured alcohol into the spray bottle filling it up about three-quarters full.

Step 2: Add water to fill the rest of the spray bottle and give a light shake.

Step 3: Spray your granite countertops with the denatured alcohol and water mix and wipe down with a clean microfiber towel. Remember to spray and clean every inch of your countertops including the undersides and the edge of your countertops. If you have backsplash this should also be used to clean that as well. The amount you spray is really up to you but I recommend a modest amount. Your towel will be damp after a few sprays in areas and if you have a larger countertop footprint you may need to replace the towel with a fresh clean towel and continue the process. I suggest spraying every 5 square feet about two or three sprays. We don’t want the liquid to penetrate the pores too much so spray and wipe immediately.

Step 4: Wipe your countertops dry with a clean, dry microfiber towel. This will prevent water spots especially if you have black countertops or a darker colored countertop.

I started my countertop company with very little and grew extremely fast because of my knowledge and helpfulness. I started this countertop resource for 1 main reason. That reason is that there are no countertop websites with all the correct information and none of them are from an industry expert like myself. I am still in the trade every single day installing countertops, educating people on the type of material they are using for their homes and making people's dream kitchens a reality.
