Quartz countertops are an increasingly popular option for kitchen and bathroom remodeling projects. Made from ground quartz crystals combined with resins and pigments, quartz offers an attractive, low-maintenance, and durable surface. However, despite quartz’s durability, stains and buildup can occur. This leads many homeowners to wonder: is vinegar safe for cleaning quartz countertops?
What is Quartz?
Quartz is an engineered stone made from roughly 90% ground quartz crystals combined with polymer resins and pigments. The resins bind the quartz particles together to form a hard, non-porous surface.
The resins make quartz resistant to heat, scratches, and stains. Pigments added to the stone during manufacturing give quartz its color and pattern. The combination of quartz aggregates and resins allows manufacturers to produce slabs in a wide variety of colors and realistic stone-like patterns.
Compared to natural stone like granite and marble, quartz offers superior durability and stain resistance. The non-porous binding resins make quartz impervious to liquids, preventing stains from seeping into the material. Quartz also resists chips, cracks, and scratches better than natural stone.
While more durable than marble or granite, quartz still requires regular cleaning to keep the surface free of dirt, grime, and buildup.
Is Vinegar Safe for Cleaning Quartz?
Vinegar has become a popular household cleaning agent due to its availability, low cost, and antimicrobial properties. However, vinegar is an acidic liquid with a pH of around 2-3. Quartz manufacturers warn against using acidic cleaners which can damage the surface and seams over time.
According to most quartz supplier warranties, mild alkaline or neutral pH cleaners are recommended. While occasional use of vinegar may not harm quartz, regular cleaning with vinegar is not advised. The acetic acid in vinegar can slowly erode the resin binders, damaging the surface and dulling the finish.
Quartz Manufacturer Recommendations
Most major quartz suppliers such as Caesarstone, Cambria, and Silestone do not recommend vinegar or other acidic cleaners for routine maintenance. Here are the general guidelines from leading quartz manufacturers:
Caesarstone does not recommend vinegar or other acidic cleaners for quartz surfaces. Their care and maintenance guide states:
- Use a mild detergent or soap and warm water for routine cleaning.
- For stubborn stains, use a non-abrasive cleaning pad with a neutral pH cleaner.
- Avoid abrasive cleaners, scrubbing pads, and acidic cleaners such as vinegar.
Cambria’s quartz care and maintenance guide gives the following recommendations:
- For daily cleaning, use a damp microfiber cloth or paper towel with warm water.
- For a deep clean, use an alkaline-based granite cleaner. Avoid acidic cleaners.
- Vinegar, lemon juice, and other acidic products can dull the surface.
Silestone’s official care and maintenance guide states:
- For routine cleaning, use a damp microfiber cloth with warm water and mild soap if needed.
- Avoid all acidic or abrasive cleaners such as vinegar, lemon, ammonia, and bleach.
- Use neutral pH cleaners formulated for stone surfaces only when needed.
Is Vinegar Completely Off Limits?
While not recommended as part of a regular cleaning regimen, distilled white vinegar can occasionally be used to remove isolated stains and buildup from quartz surfaces.
Most manufacturers agree that a diluted vinegar solution of 1 part vinegar to 20 parts water is safe for periodic use on very stubborn stains. However, acidic cleaning should be limited to isolated spots and not used across the entire surface.
For routine cleaning, it is best to stick to mild dish soap, warm water, and soft microfiber cloths or sponges. Only use a diluted vinegar solution sparingly as a last resort if needed. Thoroughly rinse and dry the surface after any vinegar application.
Best Cleaners for Quartz Countertops
To safely clean quartz and maintain the finish, it’s best to avoid vinegar and use recommended quartz-safe cleaners instead. Here are the best options:
Mild Soap and Water
For daily cleaning, most manufacturers simply recommend using a soft cloth, sponge or paper towel with warm water and mild dishwashing liquid. Avoid harsh detergents. Rinse thoroughly and dry with a clean towel.
Alkaline-based stone cleaners are formulated to dissolve grease and lift dirt without damaging the surface. Look for products labeled for engineered stone or quartz. Popular brands include StoneTech Revitalizer Cleaner and Weiman Granite Cleaner.
As a mild oxidizing agent, hydrogen peroxide can help lift stains. Mix 1 part hydrogen peroxide with 4 parts water and wipe down the surface with a soft cloth. Rinse thoroughly after cleaning.
For removing grease buildup, make a paste of baking soda and water and gently rub onto affected areas using a soft cloth or sponge. Rinse and dry thoroughly after cleaning.
Ammonia-free glass cleaners like Windex help keep quartz streak-free and shining. Spray a small amount onto the surface and wipe clean with a microfiber cloth. Avoid using glass cleaners containing vinegar or ammonia.
How to Remove Common Stains from Quartz
Accidents happen, and quartz can become stained from spills, grease, and food. Here are some safe, non-acidic ways to tackle common quartz countertop stains:
Coffee and Tea Stains
- First try rubbing the stain gently with a damp cloth and dish soap.
- For stubborn stains, apply a paste of baking soda and water and let sit for 5 minutes before scrubbing lightly and rinsing.
Grease and Oil Stains
- Immediately blot fresh grease stains with an absorbent cloth. Don’t rub the stain.
- Apply a dab of dish soap to the stain and allow to sit for 5 minutes.
- Wipe away the soap with warm water and dry thoroughly.
- For older grease stains, use a stone-safe degreasing cleaner.
Wine, Juice, and Fruit Stains
- Blot the stain right away with an absorbent cloth. Avoid aggressive rubbing.

- For dried juice stains, try hydrogen peroxide mixed with water. Apply and let sit before wiping clean.
Hard Water Stains
- Mix equal parts white vinegar and water and wipe onto the stains with a soft cloth.
- For tougher hard water marks, use a stone-safe alkaline cleaner.
- Prevent hard water stains by wiping up spills and water drops quickly.
Dried Food Stains
- First try to scrape off any clinging food debris gently with a plastic scraper.
- Apply some warm water and mild dish detergent and let it sit for 5 minutes to soften the stain.
- Gently scrub with a soft cleaning pad before rinsing clean.
How to Care for Quartz Countertops
Caring for quartz countertops doesn’t require harsh chemicals or extensive maintenance. Follow these tips to keep your quartz counters looking like new:
- Clean spills quickly to prevent stains from setting.
- For daily cleaning, use mild soap and water with soft cloth or sponge.
- Avoid abrasive pads and powders that can scratch the surface.
- Cut foods on a separate cutting board rather than directly on the quartz.
- Use trivets and hot pads under hot pots and pans to prevent thermal shock.
- Reseal quartz every 1-2 years with a stone sealer to enhance stain protection.
- Don’t stand or sit on your quartz countertops. The solid surface can crack under excessive weight.
Can Vinegar Damage Quartz Countertops?
While an occasional diluted vinegar cleaning shouldn’t harm quartz, regular use of any acidic cleaner can potentially dull the finish and deterioration over years of use.
The polymer resins that bind the ground quartz can slowly erode under repeated acid exposure. This could eventually cause the resin to break down, damaging the structural integrity of the material.
To avoid long-term damage:
- Use vinegar sparingly for isolated stains only.
- Limit vinegar to a heavily diluted solution of 1:20 vinegar to water.
- Avoid wiping down the entire surface with vinegar. Spot treat only.
- Immediately rinse and dry the surface after using vinegar.
- Stick to mild, pH-neutral cleaners for daily maintenance.
