How to Deep Clean Quartz Countertops

Quartz countertops are an increasingly popular choice for kitchens and bathrooms due to their durability, stain resistance, and stylish appearance. However, even quartz requires occasional deep cleaning to keep it looking its best. Here is a comprehensive guide on how to deep clean quartz countertops.

Why Quartz Countertops Need Deep Cleaning

While quartz is non-porous and resistant to most stains, it is not impervious. Over time, dirt, grime, and bacteria can build up on the surface. Oils and residues from food can also leave a film. Deep cleaning helps remove these accumulations to restore the countertop’s original beauty and luster.

Deep cleaning is especially important for hygiene in kitchens. Bacteria, molds, and germs can harbor in dried-on spills. A thorough deep cleaning helps sanitize the countertop.

Finally, a good deep clean rejuvenates the entire surface. It gets into crevices and etched areas that daily wiping may miss. The result is a quartz countertop that looks like new again.

Supplies Needed

  • Microfiber cloths
  • Soft scrub brush
  • pH-neutral stone cleaner or mild dish soap
  • Clean bucket of warm water
  • Clean towel

Avoid abrasive cleaners and scouring pads as they may scratch the quartz surface. Acidic cleaners should also be avoided.

Step-by-Step Guide

Follow these steps for how to deep clean quartz countertops:

1. Remove Everything from the Countertop

Clear everything off the countertop – small appliances, kitchen tools, decorative items. This gives you access to the entire surface area.

2. Mix Cleaning Solution

Fill a bucket with warm water and add a few drops of pH-neutral stone cleaner or mild dish soap. Too much cleaner can leave a film, so use sparingly.

3. Wipe Down the Surface

Dip a microfiber cloth in the cleaning solution and wring it out so it is damp but not dripping. Wipe down the entire counter, scrubbing gently if there are dried-on spills.

4. Clean Etched Areas

Examine the countertop for any dulled or etched spots. Apply more cleaning solution directly to these areas and scrub with a soft brush. Avoid scouring too hard.

5. Rinse the Surface

Dip a clean microfiber cloth in fresh water and wring it out well. Use this to wipe all over the countertop. This removes any residual cleaner and soil.

6. Dry the Countertop

Take a clean, dry towel and buff the countertop. Make sure no moisture remains on the surface. Allow the quartz to fully air dry as well.

7. Inspect and Repeat if Needed

Check over the countertop. If any stubborn spots remain, repeat steps 3-6 in those areas until the quartz is uniformly clean.

8. Reseal if Necessary

Quartz itself does not require sealing. But if the grout lines look dull or show accumulated grime, use a sealant formulated for quartz grout.

Tips for Quartz Countertop Care

  • Wipe up spills immediately to prevent stains.
  • Use a cleaner made specifically for quartz. Avoid bleach or acidic cleaners.
  • Disinfect periodically with a quartz-safe disinfecting wipe.
  • Avoid putting hot pots or pans directly on the surface. Use trivets.
  • Don’t use quartz as a cutting surface. Always use a cutting board.
  • Reseal grout lines every 1-2 years.
  • Avoid using rubber mats or dyed bath mats, as they can stain quartz.

How Often to Deep Clean Quartz

  • Kitchen countertops: Every 1-2 months
  • Bathroom vanities: Every 3-4 months
  • Less used surfaces: Every 6 months

Increase frequency if your countertops get heavy usage or visible buildup.
