Homemade granite cleaner (recipe)
When we remodeled our kitchen 7 years ago we replaced our old Formica countertops with granite. The granite we chose is exceptionally dense and non-porous and we haven't had to reseal it since it was installed. It also helps that we've avoided harsh cleaners (windex, vinegar, ammonia or citrus based cleaners) that can etch the surface or strip away the sealer.
I've been using a simple homemade recipe that the installer gave me and thought I'd post it here. The Isopropyl cleans and disinfects but it's a neutral cleaner so it doesn't harm the stone. Just spray the cleaner on the surface and wipe dry. Before using this concoction I researched it online and it is the standard recipe with only a few changes - some sites added 1/2 cup alcohol or used Vodka, others increased the dish detergent and others added 5 to 10 drops of essential oil to mask the alcohol smell. While I just use a paper towel many recommended using a microfiber cloth helps to eliminate streaks.
One quart spray bottle
1/4 cup Isopropyl rubbing alcohol
1 tsp. Dawn detergent
water to fill bottle
