Can You Use Ammonia to Clean Quartz Countertops?


Quartz countertops are popular in kitchens and bathrooms because of their beauty, durability, and low maintenance. However, like any surface, quartz countertops require proper cleaning to keep them looking pristine. Some homeowners wonder if using ammonia is safe for cleaning quartz.

Can You Use Ammonia to Clean Quartz Countertops?

The short answer is no, ammonia should not be used to clean quartz countertops. While ammonia is a strong cleaning agent, it can dull the shine of quartz and damage the surface over time. Quartz manufacturers specifically advise against using ammonia-based cleaners.

Instead, mild soap and water or specialized quartz cleaners are recommended for routine cleaning. Avoid abrasive cleaners or pads as they can also damage the quartz.

Below we will explore in more detail why ammonia should be avoided for quartz countertop care and the best practices for keeping them looking like new.

Why You Should Not Use Ammonia on Quartz

There are a few key reasons why ammonia is problematic for cleaning quartz countertops:

  • It can damage the finish – Quartz has a glossy, non-porous surface that gives it a smooth, glassy look. The polymers that make up this surface can be degraded by harsh cleaners like ammonia.
  • It leaves streaks and film – Ammonia does not rinse cleanly off quartz. Using it often leaves unsightly streaks, residue, and film behind on the surface.
  • It leads to discoloration – With repeated use, ammonia can cause quartz to become dull and discolored over time. This damage is irreversible.
  • Voids the manufacturer’s warranty – Using ammonia or other harsh cleaners on quartz goes against the manufacturer’s care recommendations, which can void the warranty if damage occurs.

To keep quartz counters looking pristine and avoid potential damage, ammonia cleaners should always be avoided.

Best Cleaning Practices for Quartz Countertops

To safely clean quartz, follow these best practices:

Use Mild Soap and Water for Daily Cleaning

For routine cleaning, a mild dish soap diluted with warm water is all you need. The key is using a gentle, non-abrasive soap that will not strip or dull the finish. Thoroughly rinse the quartz after cleaning with soap and water.

Opt for Specialized Quartz Cleaners

There are specially formulated cleaners made just for quartz that are safe and effective. Look for ones that state they are suitable and PH-balanced for quartz. Never mix different cleaners together.

Clean Up Spills Quickly

Due to the non-porous nature of quartz, spills and stains tend to sit on the surface rather than absorb in. Be sure to wipe up food, liquids, grease, etc. promptly to prevent staining.

Avoid Abrasive Pads and Cleansers

Stay away from rough sponges, brushes, or scrubbing pads marked as abrasive. Also avoid powdered cleansers that contain bleach, hydrogen peroxide, or lemon/vinegar. Anything too gritty or acidic can erode quartz over time.

Rinse with Clean Water after Any Cleaner

Never leave cleaning solutions or soapy residue sitting on quartz. Always rinse thoroughly with clean water after using any cleaner to prevent streaking. Dry with a soft cloth.

Consider Resealing Once a Year

While quartz itself is non-porous, the seams are more vulnerable to staining. Having your quartz resealed about once a year will protect against leaks through the seams.

Quartz Countertop Cleaning FAQs

Can I use other household cleaners on quartz?

No. Avoid glass cleaners, tile cleaners, bleach, vinegar, hydrogen peroxide, or any cleaner containing oils, lemon, or citrus. Only use cleaners specifically made for quartz.

How can I get dried soap scum or hard water marks off my quartz?

Try a diluted white vinegar and water solution for this type of stuck-on buildup. Spray it on, let it sit for a few minutes, then scrub with a soft cloth or sponge rinse thoroughly. This can help dissolve soap scum without damaging the quartz.

Are quartz countertops heat resistant?

Quartz is more heat-resistant than many other counter materials. However, prolonged direct heat exposure can cause damage. Always use trivets or hot pads when placing hot pots, pans, etc. on quartz.

Can quartz counters get scratched or chipped?

While quartz is very durable, it’s not completely impervious to damage. Excessive force with hard or sharp objects can potentially scratch, chip, or crack quartz. Be careful about heavy impacts against edges and use cutting boards.

How long do quartz countertops last?

With proper care and maintenance, quartz countertops can last for many decades in good condition. The resins that make up the material are very durable and stain-resistant.


Regular cleaning with mild, pH-balanced soaps and immediately wiping up spills is the best way to keep quartz looking like new. Always avoid ammonia-based cleaners, abrasive pads, acidic solutions, and harsh chemicals that can degrade and discolor the surface over time. With the right gentle care, quartz countertops can stay beautiful for years of daily use. Be sure to use specialized quartz cleaners and reseal the seams annually for optimal results. Following these best practices will keep your quartz counters in excellent shape.
