Everyday cleaning
- Clear crumbs with a soft cloth or brush so they do not scratch the finish as you wipe.
- Spray a pH-neutral cleaner made for stone, or for quartz, warm water with a little mild soap.
- Wipe with a soft microfiber cloth.
- Dry the surface, especially around the faucet, where hard water leaves white mineral buildup over time.
The Natural Stone Institute’s experts advise against everyday dish detergent on granite, because soap can leave a film that dulls and streaks the polish. A cleaner made for stone does not.
By material
| Material | Use | Avoid |
|---|---|---|
| Quartzite and granite | pH-neutral stone cleaner, warm water | Vinegar, lemon, bleach, ammonia, abrasive powders and pads |
| Dolomite and marble | pH-neutral stone cleaner, warm water; wipe spills quickly | Anything acidic, which etches: vinegar, citrus, many bathroom cleaners |
| Engineered quartz | Mild soap and water, or a cleaner the maker approves | Oven cleaner, paint strippers, bleach, high-pH degreasers and sealers |
Never use these on natural stone
- Vinegar, lemon juice or other acids. They etch marble and dolomite and wear down the sealer on granite.
- Bleach and ammonia, which break down sealers. Never mix them; together they make a toxic gas.
- Scouring powders, creams and green scrub pads, which scratch the polish.
- Glass and general-purpose cleaners unless the label says they are safe for stone.
Habits that protect stone
- Use cutting boards. Stone will dull your knives, and grit trapped under a knife can scratch.
- Use trivets for hot pans, coasters under glasses, and a tray under oil and soap bottles.
- Wipe spills right away, especially oil, wine, coffee and citrus.
- Test the sealer once a year; see sealing stone countertops.
Common questions
Can I clean granite with vinegar?
No. Vinegar is an acid; over time it dulls the polish and breaks down the sealer. Use a pH-neutral stone cleaner.
Is dish soap safe on granite?
A little won’t harm it, but used every day it can leave a dull film. A cleaner made for stone is better for daily use.
How do I clean quartz countertops?
Warm water and mild soap on a soft cloth. Avoid harsh chemicals such as oven cleaner and bleach, which can damage the resin.
How do I get rid of a stain?
Most stains in stone come out with a poultice. See removing stains from stone.
