Caring for Your Stone Countertops

  1. Clean your counters regularly with mild soap and water. For best results, use a cleaner made specifically for quartz or natural stone and marble countertops. Keystone recommends Stonetech® Revitalizer® Cleaner and Protector.
  2. After cleaning your countertops, always dry your surface with a clean, soft cloth to remove watermarks and eliminate any buildup.
  3. Avoid harsh cleaners with abrasives that may scratch your surface, and those with acidic ingredients—like lemon and vinegar—that dull its sheen. Also avoid glass cleaners which may leave a waxy buildup on your countertops.
  4. Remove spills immediately—blot with paper towel, as wiping or rubbing will spread the mess. Flush area with mild soap and water, rinse several times, and dry thoroughly with a soft cloth.
  5. Use coasters or napkins under beverages, particularly those containing alcohol or citrus juices.
  6. Use hot pads or trivets. Natural and engineered stones are innately heat resistant—however, heat can eventually break down the sealers and surface resins.
  7. Avoid using your countertop as a cutting board. Not only can it leave scratches on your surface over time, but it also dulls and ruins your knives.

Keystone’s engineered countertops are non-porous and stain resistant, so they do not require any sealing. If you have selected a natural stone, like marble or granite, it is by nature porous. Keystone provides a sealer for your countertops to improve the life of your stone. We use STONETECH® Bulletproof® Sealer. If water no longer beads on your countertop, we recommend that you have it professionally resealed.

STONETECH® includes one of the industry’s best warranties, with a 25-year fully transferable residential countertop warranty and a 15-year commercial and industrial countertop warranty. A one-year outdoor countertop warranty is also available on select granite options.
  1. Remove any loose debris.
  2. Blot spills; wiping the area will spread the spill.
  3. Flush the area with plain water and mild soap, and rinse several times.
  4. Dry the area thoroughly with a soft cloth.
  5. Repeat as necessary.
  6. If the stain persists or for problems that appear too difficult to treat, call your stone care professional, installer, or restoration specialist.
