Caring for Quartzite Countertops: A Walnut Creek Homeowner's Guide

Quartzite is the fastest-growing material in Walnut Creek kitchens — and the one homeowners most often worry about caring for. The good news: maintenance is much simpler than you think.

We install quartzite in more Walnut Creek kitchens every year — Northgate, Rossmoor, Tice Valley, Saranap. After install, the most common question we get is: 'How do I take care of it?' Here's the simple version, and the slightly longer version.

The simple version

• Wipe up spills (especially anything acidic — lemon, wine, vinegar) within a few minutes.
• Clean with mild dish soap and warm water. That's it.
• Reseal once a year. A bottle of impregnating sealer costs $25 and takes 10 minutes.
• Use cutting boards. Quartzite is very hard, but knives will dull and edges can chip.
• Use trivets for cast iron straight off the burner. Quartzite handles heat well — thermal shock from extreme temperature changes is the real risk.

Sealing — what, when, why

Quartzite is a natural stone, so it's slightly porous. Sealer doesn't sit on top — it penetrates into the surface and blocks liquids from soaking in. The right product is a high-quality impregnating sealer (we recommend Dry-Treat Stain-Proof Plus or Miracle 511).

How to test if you need to reseal: drip a tablespoon of water on the counter and let it sit 10 minutes. If the stone darkens underneath, it's time. Wipe up, let dry overnight, then reseal in the morning.

What to clean with

• GOOD: mild dish soap, warm water, microfiber cloth. Stone-safe cleaners (Method daily granite, Weiman granite cleaner).
• AVOID: vinegar, lemon, bleach, ammonia, abrasive scrubbing pads, generic 'all-purpose' sprays. These will dull or etch the surface over time.

What if something stained?

For an oil-based stain (olive oil, butter), make a paste of baking soda and water, apply over the stain, cover with plastic wrap, let sit overnight. The paste pulls the oil up out of the stone. For a water-based stain (coffee, wine), do the same with hydrogen peroxide instead of water. Then reseal that area.

When to call us

Etching, chips, seam issues, or a stain that didn't lift with the steps above — those are repair territory. We service every countertop we install (and many we didn't) across Walnut Creek and the East Bay.
