How to Clean Quartz Countertops Safely

Meta description: Learn the best and safest methods for cleaning quartz countertops. This in-depth guide covers daily cleaning, stubborn stains, and disinfecting quartz.


Quartz countertops are popular in many homes for their durability, aesthetics, and low maintenance. However, even quartz requires regular cleaning to keep it looking beautiful. Cleaning quartz the wrong way with abrasive cleaners can damage the surface.

In this comprehensive guide, we will discuss the safest and most effective ways to clean quartz countertops. Proper cleaning is essential to prevent etching, scratches, and stains. We will cover recommended products, techniques, and methods for daily cleaning, sanitizing, polishing, and removing stubborn stains from quartz.

Use Mild Soap and Water for Daily Cleaning

For routine cleaning, a mild soap and water solution is all you need. Avoid harsh cleaners and abrasive sponges and pads, which can dull and scratch the quartz.

Here’s a simple method for daily cleaning of quartz:

  • Mix a few drops of mild dish soap like Dawn in warm water. Avoid sudsy, citrus, or oil-based soaps.
  • Use a soft microfiber cloth, sponge, or paper towel dampened with the soap solution.
  • Wipe the countertop surface with the damp cloth in circular motions. Apply light pressure.
  • Rinse with clean water and dry with a soft towel.

This removes most dirt, dust, and grime from daily use. For best results, clean quartz daily or after preparing meals. The mild soap formula is safe for routine cleaning.

Use a Specific Quartz Cleaner

Look for a cleaning product specifically formulated for quartz. These contain gentle surfactants and polymers to lift dirt. Popular options include:

  • StoneTech Revitalizer Cleaner
  • Method Daily Granite & Stone Cleaner
  • Granite Gold Daily Cleaner
  • Weiman Granite Cleaner & Polish

Spray a small amount of the quartz cleaner directly on the countertop. Use a soft cloth or sponge to spread and wipe the surface. No need to rinse after. These specialized cleaners help dissolve stuck-on messes without dulling the quartz finish.

Avoid Certain Cleaners

Do not use these damaging cleaners on quartz:

  • Window cleaners like Windex
  • Vinegar or bleach solutions
  • Abrasive powders and scrubs
  • Alkaline cleaners with high pH
  • Oil soaps
  • Citrus cleaners

Vinegar, lemon juice, bleach, and alkaline cleaners etch and dull quartz surfaces. And abrasive cleaners like Comet or Soft Scrub scratch the finish. Stick to mild soaps and specialized stone cleaners only.

How to Disinfect Quartz Countertops

Sanitizing quartz periodically kills germs and bacteria. Here are safe ways to disinfect without harming the surface:

Diluted Bleach Solution

Make a gentle bleach cleaning solution for disinfecting:

  • 1/3 cup bleach
  • 1 gallon water
  • 1-2 drops dish soap (optional)

Mix the solution in a spray bottle. Spray directly on the quartz and wipe clean with a paper towel after 5 minutes. Avoid bleach contact with metal fixtures. This kills 99.9% of bacteria and viruses.

Rubbing Alcohol

Undiluted 70% isopropyl alcohol works to sanitize quartz. Pour a small amount on a clean cloth and wipe the surface. No need to rinse. The alcohol evaporates rapidly. Repeat weekly or as needed.

Hydrogen Peroxide

Mix 1 part 3% hydrogen peroxide with 4 parts water. Spray or wipe this solution onto the quartz countertop and allow to sit for 5 minutes before wiping dry with a clean cloth. Hydrogen peroxide is an effective natural disinfectant.

Other Tips:

  • Quartz can withstand higher heat than many competing surfaces. But prolonged heat exposure can damage it over time. Use trivets under hot pans and baking dishes to prevent cracking and dulling.
  • For water spots and mineral deposits, use a cleaning polish made specifically for quartz. Apply a small amount to the stain and buff clean. Avoid lime-removing cleaners.
  • Don’t cut food directly on quartz. Use a cutting board to avoid dulling and scratching.
  • Blot up spills immediately before they have a chance to soak in and stain.
  • Avoid placing toiletry products directly on your quartz vanity top. Chemicals in hair products, cosmetics, and skincare can etch the surface.

By using the proper techniques and cleaners, you can safely keep quartz counters looking like new for years. Always test cleaning products on a small inconspicuous area first. With regular light cleaning and occasional deep cleaning, quartz is an easy-care and durable countertop option.

How to Remove Dried Spills and Stains from Quartz

Accidents happen. Quartz is prone to staining from spills – like wine, coffee, and oil – that are left to dry on the surface. Here are the most effective ways to remove dried stains without damaging the quartz.

Baking Soda Paste

Make a paste with baking soda and water. Apply it to the stain and let sit for 5 minutes. Scrub gently with a soft cloth or sponge. Rinse and dry thoroughly. Baking soda is a mild abrasive that lifts stains without dulling quartz.

Hydrogen Peroxide

Use 3% hydrogen peroxide straight from the bottle. Let it bubble on the stain for 2-3 minutes. Wipe clean. No need to rinse. The oxidizing properties in hydrogen peroxide help remove discoloration.

Bleach Gel

Apply a chlorine bleach gel directly to the stain. Let it sit for up to 5 minutes before rinsing. This targets tough dried-on stains.

Magic Eraser

Dab a wet Magic Eraser sponge on the mark and rub gently. Avoid excessive scrubbing. Magic Erasers work well to lift stains without scratching.

Glass Cooktop Cleaner

These specialized cleaners like Cerama Bryte and Weiman are designed to remove cooked-on food from stove tops. They can work to lift dried spills from quartz too. Apply and let sit before wiping clean.


For soap scum and hard water marks, use a half-and-half solution of ammonia and water. Wipe the solution onto the stain and rinse thoroughly after 5 minutes.

Always follow up spot cleaning with a rinse and dry to avoid streaks. With the right technique, even dried-on stains can be removed to restore the quartz finish.

How to Remove Etches and Scratches from Quartz

Etch marks appear as dull, foggy spots on quartz. These are caused by acid-based cleaners and spills. Scratches are superficial surface abrasions. Here are some tips for fixing these surface flaws:

Baking Soda & Water Paste

Make a paste with baking soda and water. Gently rub it into the etch mark using a soft cloth or buffing pad. Rinse thoroughly. For lighter etches, this can help buff out the damage.

Fine Sandpaper

For shallow scratches, use 600 grit wet-dry sandpaper lubricated with water. Gently sand in a circular motion. Start with light pressure. Be careful not to create deeper grooves.

Etch Remover Products

Use an etch mark remover specifically formulated for quartz. Popular options are Granite Gold Etch & Mark Remover or StoneTech Heavy Duty Scratch Remover. Apply a thin layer to the affected area. Allow 2-3 minutes of dwell time before wiping.

Diamond Pads

Rub a hand-held diamond polishing pad over etches and scratches. Apply moderate pressure. These pads come in varying grits – 50, 100, 200, and 400. Work up to finer grits to restore the smooth factory finish.

Polishing Compound

After sanding or diamond pads, apply a quartz-safe polishing compound like Stoneline Polish. Use a microfiber cloth to buff out Sand in circular motions. Finish by rinsing and drying completely. The compound will create a light protective coating.

Professional Help

For deep scratches and damage, hire a professional stone restoration company. They have specialized equipment to re-polish and resurface the quartz. This yields the best results for severe etching and scratches.

While it’s not possible to fully repair all damage, these techniques can significantly improve the look of etched and scratched quartz. But prevention is key – always use trivets and proper cleaners.

How to Clean Quartz Countertop Edges and Backsplash

The edges and backsplashes on quartz countertops also need regular cleaning. Here are some tips:

  • For food, dirt, and water spots, use a soft cloth with a mild soap and water solution.
  • Rinse soap residue thoroughly to avoid streaks.
  • Clean backsplashes first, then work down edges and surfaces.
  • Use a soft bristled toothbrush dipped in soap and water to scrub debris from textured edges and bevels.
  • For hard water deposits on backsplash, spray with white vinegar and let sit 5 minutes before scrubbing and rinsing.
  • Avoid using razor blades or scrapers which can nick and scratch the quartz edges.
  • For stubborn dried food, grease, or soap scum on edges, spray with an ammonia-free glass cleaner and let penetrate for 2-3 minutes before wiping.
  • Sanitize edges and backsplash periodically with diluted bleach or isopropyl alcohol solutions.
  • Buff edges and backsplash after cleaning to polish and shine using microfiber cloths.

Regular attention to edges prevents a buildup of grime that is harder to remove. Take extra care when cleaning near walls and vertical surfaces. With routine cleaning, the edges and backsplash will stay looking new.

How to Clean a Quartz Sink

Quartz is also commonly used for kitchen and bathroom sinks. Here are tips for cleaning quartz sinks:

  • Everyday cleaning – Wipe the sink basin with a soft cloth, mild soap, and warm water after use. Rinse thoroughly.
  • Disinfecting – Periodically sanitize with a diluted bleach solution or rubbing alcohol. Let sit 5 minutes before rinsing.
  • Remove stains – Make a paste with baking soda and water. Apply to stains and scrub gently with a soft brush or sponge before rinsing.
  • Remove residue – For soap scum, toothpaste, and mineral deposits, spray with white vinegar and let sit for 5 minutes. Scrub and rinse.
  • Avoid abrasives – Do not use abrasive scrubs or scouring pads, which can scratch and damage quartz.
  • Soften water – Install a water softener if you have hard water issues to prevent limescale buildup.
  • Protect finish – Always use a bottom grid, rack, or mat to prevent metal pans and objects from damaging the quartz surface.

By following these cleaning methods, a quartz sink will stay beautiful and sanitary. Take care to avoid scratching or etching this surface. With proper care, a quartz sink is highly durable in kitchens and baths.

Tips for Cleaning Other Quartz Surfaces

In addition to countertops and sinks, quartz is used for:

  • Shower walls and floors
  • Fireplace surrounds
  • Tabletops
