What Cleaners Are Safe To Use On Quartz Countertops?

Quartz countertops are an increasingly popular choice for modern kitchens and bathrooms due to their durability, aesthetics, and low maintenance. However, like any surface, quartz requires proper care and cleaning to keep it looking pristine. Using the wrong cleaners can damage the sealant layer and lead to staining and etching in the stone. Here is a guide to choosing the safest cleaners for quartz countertops.

Why Proper Cleaners Are Essential For Quartz

Quartz is composed of ground natural stone and polymer resins. While very hard and scratch-resistant, the resin layer on the surface can be damaged by harsh chemicals. Acidic cleaners in particular can etch into the finish and open up pores for stains and bacteria growth. Abrasive cleaners also slowly grind away the glossy appearance over time. That’s why you need to be careful and use only pH neutral cleaners free of acids, alkalis, bleach or ammonia. Gentle cleaners help preserve the factory sealant and prevent dull spots.

Recommended Daily Cleaners For Quartz Countertops

pH Neutral Stone Soap

  • Gentle enough for daily use
  • Won’t strip away protective sealant
  • PH balanced formula is non-acidic
  • Safe for sealing natural stone pores
  • Retains shine and polish of countertops

Diluted Dish Soap

  • Use mild unscented liquid dish soap
  • Dilute with water at 1:20 ratio
  • Avoid soaps with additives like bleach, alkalis etc
  • Rinse thoroughly after washing

Microfiber Cloth

  • Prevents scratches from paper towels
  • Safe for all stone surfaces
  • Lint-free and reusable
  • Distilled white vinegar for spot cleaning

Cleaners To Avoid On Quartz Surfaces


While vinegar is mild, frequent use can etch quartz over time. Use occasionally for spot cleaning.

Citrus Cleaners

The acidic juices in citrus can damage sealant and cause etching. Avoid using them.

Bleach-Based Cleaners

Hypochlorites in bleach can react with resins and cause yellowing. Don’t use on quartz.

Alkaline Cleaners

Harsh alkaline cleaners damage the sealant and strip the glossy finish. Prevent contact.

Abrasive Cleaners

Abrasives in powders, creams and scrubbing pads create hairline scratches. Use a soft cloth instead.

Ammonia-Based Cleaners

These can discolor quartz surfaces over time. Rinse immediately if in contact.

Tips For Cleaning Quartz Countertops

  • Blot spills quickly before they set
  • Use coasters under bottles to prevent etching rings
  • Rinse soap residues thoroughly after cleaning
  • Reseal quartz annually for added protection
  • Avoid exposing quartz to direct UV light for long periods

Can You Use Household Cleaners on Quartz?

Many common household cleaners are too harsh for quartz and should be avoided. Here are some examples:


The ammonia in Windex can discolor and pit quartz over time. Use a vinegar dilution instead.

Comet or Ajax

Abrasive powders leave behind hairline scratches on the surface. Use non-abrasive formulas only.

Mr Clean Magic Eraser

The melamine foam is highly abrasive and will damage the finish. Don’t use this on quartz.


This is too alkaline and can react with the resin layer, causing etching. Rinse immediately if in contact.

Baking Soda

While non-abrasive, baking soda is mildly alkaline and can strip the sealant if used frequently.

Multipurpose Sprays

Citrus oils, ammonia and abrasives in these make most unsuitable for quartz.

Homemade Cleaners Safe For Quartz

Distilled White Vinegar Mix

  • 1 part white vinegar
  • 20 parts water

Essential Oil Mix

  • 10 Drops lemon/orange essential oil
  • 1 Tablespoon mild dish soap
  • 1 Quart warm water

Rubbing Alcohol

  • For dried spills and sticky residue

Hydrogen Peroxide

  • Helpful occasionally for disinfecting

Frequently Asked Questions

Can I use rubbing alcohol to clean quartz?

Yes, rubbing alcohol is safe for occasional use on quartz for dried spills and sticky residue. Ensure the quartz is properly sealed first.

What about hydrogen peroxide?

In diluted amounts, hydrogen peroxide can be used occasionally for disinfecting quartz surfaces without damage. But avoid frequent use.

Is it ok to use baking soda on quartz?

Baking soda is mildly abrasive and alkaline so frequent use will damage sealant over time. Use occasionally for spot cleaning only.

How do I get rid of hard water marks on quartz?

Hard water spots can be cleaned with a paste of baking soda and water. Rub gently and rinse well. Vinegar also helps remove buildup.

Does quartz need to be sealed?

Quartz comes pre-sealed from factories. But annual resealing is recommended for added protection, especially for heavily used surfaces.

How often should I clean quartz countertops?

For daily maintenance, wiping with a damp microfiber cloth is sufficient. Deep clean quartz 1-2 times a week using only pH neutral stone cleaners.


Quartz countertops add beautiful, functional living spaces but require safe, non-abrasive cleaners that won’t compromise the protective sealant layer. Always check product labels and refrain from using vinegar, citrus, bleach, alkaline, ammonia and abrasive based cleaners which can damage the resin finish over time. With some care, your quartz countertops will stay looking pristine for years.
