The Right Way to Clean Granite | Realtor Magazine
It’s important that those granite countertops gleam during showings, but some cleaning products may actually harm them. White vinegar, for example, has been a popular cleaning agent because it’s inexpensive and can combat bacteria and mold on many surfaces, such as glass and linoleum. But the acid in the vinegar can gradually ruin the finish of granite and wear away at the protective sealant, according to a new article at Apartment Therapy.
Acid-based cleaners such as lemon juice or citric acid—which can be found in many all-purpose cleaners—wear away the sealant, the article warns. Instead, clean granite countertops with mild soap and water. To disinfect counters, use isopropyl alcohol, along with soap and water, or commercial granite cleaners.
