THE DOs AND DON’Ts OF CLEANING GRANITE
DO: Make sure your granite counter-top is sealed. While granite is a very hard surface and less porous than marble, unsealed or weakly sealed granite will soak up oils, spills, and stains. To check whether your granite is sealed, leave a few drops of water on the surface. If it beads up, you have a secure seal. If after a few minutes the water has soaked into the granite, then it’s time to reseal the stone.
DO: Wipe up spills as soon as you notice them.
DO: Use warm water, a mild or gentle dish soap, and a nubby washcloth or microfiber cloth for daily wipedowns.
DON’T:Use harsh or abrasive cleaners and sponges, Windex, acidic cleaners like vinegar, lemon, lime, or anything with ammonia or bleach. Frequent use of these chemicals will dull and weaken the sealant over time. Basically, the harsher the cleaner, the quicker it will break down the sealant.
What About Disinfecting?
A well-sealed granite counter-top is relatively impervious to bacteria. Hot water and dish soap should be adequate for daily sanitizing. However, if a stronger disinfectant is desired, mix together a 50:50 solution of water and 91% isopropyl alcohol. Spray onto the granite, allow to sit for 3-5 minutes, then rinse with water and dry with a clean microfiber cloth. Avoid bleach or ammonia-based cleaners.
What About Special Granite-Safe Cleaners?
There are granite cleaners out there, like this one from Method and this one from Granite Gold. Some all-purpose surface cleaners also specify that they’re safe for granite. Use these cleaners if you want — just know that you don’t have to buy them if you don’t want to.
