How to Sanitize a Quartz Countertop

Sanitizing quartz countertops regularly is an important part of keeping them clean, hygienic, and looking their best. Quartz is a very durable material that can withstand daily use, but it still requires proper care and maintenance. Following these steps will help you properly sanitize your quartz countertops.

What You’ll Need

  • Mild dish soap or stone cleaner
  • Clean microfiber cloth
  • Soft bristle brush
  • Bucket of warm water

Cleaning Process

Sweep Away Loose Debris

First, use a soft bristle brush to gently sweep away any loose crumbs or debris on the countertop. This prevents anything from getting scrubbed into the surface later on. Discard any collected debris into the trash.

Mix Soap Solution

Fill a bucket with warm water and add a small amount of mild dish soap or stone cleaner. Refer to the product label for exact dilution ratios. The warm water helps the cleaner dissolve and lift away grime.

Wash the Surface

Dip the microfiber cloth into the soapy solution then wring out excess water. Wash the entire countertop surface using broad circular motions. Apply light pressure as you clean. Rinse and re-wet the cloth as needed.

Pay Attention to Grout Lines

Use a small amount of the soapy solution and a grout brush to gently scrub along the countertop grout lines. Rinse thoroughly with clean water. Grout is porous and more likely to harbor bacteria.

Rinse and Dry

Once the entire countertop surface is cleaned, rinse thoroughly with fresh clean water to remove all soap residue. Wipe dry with a clean soft cloth. Allow the surface to air dry completely.

Disinfect (Optional)

For periodic disinfection or after food prep, wipe the countertop down using a soft cloth sprayed with an antimicrobial cleaner or mild bleach solution. Let it sit 3-5 minutes before rinsing clean.

Cleaning Tips

  • Avoid abrasive scouring pads or powders that can dull the quartz surface.
  • Blot up spills quickly to prevent staining, especially oils, wine, and acidic foods.
  • For tough dried-on messes, let a damp cloth soaked in soapy water sit on the spot for a few minutes before scrubbing.
  • Reseal and polish quartz yearly to protect shine and prevent buildup.
  • Follow manufacturer’s care instructions for your specific quartz product.

Properly sanitizing your quartz countertops doesn’t require harsh chemicals or a ton of effort. With some mild soap, water, and a soft cloth, you can easily remove most messes while keeping quartz looking like new. Be sure to disinfect periodically and promptly clean up spills for a healthy, hygienic kitchen!
