Granite and quartz countertops continue to be an exceptionally popular option, thanks to the plethora of styles available and the durability of natural stone.  Caring for your solid-surface countertops is easy, too - with these tips you'll be sure to love and protect your investment for years to come.  


As indestructible as your granite or quartz countertop seems, it's important to care for it daily to maintain it's beauty long-term.  Here are a few tips:

  • Even when sealed, stone is porous. Use coasters to prevent water rings and be sure to wipe up spills promptly to avoid water marks, stains and etching.

  • Do not place hot items directly on your stone surface as heat may cause cracking. Use trivets or hot pads to diffuse the warmth.

  • Stone may scratch. Avoid cutting directly on the surface by using a cutting board.

  • Regularly wipe your surface (cleaning suggestions below) free of spills and debris.


A well-sealed countertop will be impervious to bacteria and grime; hot water, mild soap and a cloth or sponge are all you need on a daily basis to keep things clean.  Be sure to avoid acidic cleaners, those with harsh chemicals, vinegar, bleach, ammonia, lemon and lime.


Most granite and nearly all quartz countertops are sealed prior to installation.  If you're wondering whether your countertop seal is in tact, spill a bit of water on it.  If the water beads up, your seal is in good shape.  If the water begins to seep into the surface, it is time to re-seal.  At a minimum, it's a good idea to seal your countertops once a year; depending on use you may need to do so as frequent as once per quarter.

Sealing your countertops takes only a few minutes, thanks to spray-on formulas found at most hardware stores.  Apply the sealant to clean countertops, let it sit per the directions on the bottle, and wipe it off.
