How to Clean Stain Quartz Countertops

Having quartz countertops can provide an elegant and durable surface in your kitchen or bathroom. However, like any countertop material, quartz can become stained over time with spills and regular use. Fortunately, quartz is non-porous, making it resistant to stains and much easier to clean than natural stone. Here is a comprehensive guide on how to clean stain quartz countertops and restore their beauty.

What Causes Stains on Quartz Countertops

Quartz countertops are stain-resistant, but not completely stain-proof. Here are some common causes of stains:

Oils and grease – Cooking oils, butter, and greasy foods can leave behind a residue that leads to stains over time.
Wine and coffee – The pigments in dark liquids like wine, coffee, and juice can stain if left on the surface.
Metal marks – Pots, pans, and metal utensils may scrape or leave marks on the countertop.
Hard water spots – Mineral deposits in hard water can leave behind spotty stains.
Mold and mildew – Excess moisture can allow mold and mildew to grow, leaving stains and discoloration.
Harsh chemicals – Cleaners and chemicals containing dyes or acids can etch or stain the quartz surface.

Cleaning Supplies for Quartz Countertops

Having the right cleaning supplies is key to safely remove stains without damaging the quartz. Here are some recommended cleaners:

Mild dish soap – A small amount of non-abrasive dish soap diluted in warm water works well for most stains. Avoid overly concentrated or harsh formulas.
Stone cleaner – Specialty stone cleaners are designed to lift stains while being gentle on natural stone and quartz.
Baking soda – The abrasiveness of baking soda can help scrub some stains, but avoid excessive scrubbing.
Hydrogen peroxide – The bubbling action of peroxide can help lift some stubborn stains.
Vinegar – For hard water stains, white vinegar diluted with water can dissolve mineral deposits.
Nylon brush or sponge – Use a soft brush or non-abrasive sponge to gently scrub stains in a circular motion.

Avoid abrasive cleaners, bleach, ammonia, alcohol, or acidic cleaners, as these can dull or etch quartz surfaces.

How to Remove Common Stains from Quartz

Follow these methods to safely lift specific stains from quartz countertops:

For Oils and Grease Stains:

Mix a few drops of dish soap into warm water.
Dip a soft sponge into the solution and wring out excess water.
Gently scrub the stained area using small circular motions.
Rinse thoroughly with clean water and dry with a soft cloth.
For stubborn grease stains, let the soapy solution sit for 5 minutes before scrubbing.

For Wine, Coffee, and Juice Stains:

Make a baking soda paste by sprinkling baking soda onto the stain and adding just enough water to form a spreadable paste.
Let the paste sit for 5-10 minutes.
Use a soft bristle brush to gently scrub the paste over the stain.
Rinse thoroughly and dry with a soft cloth.
For stubborn stains, repeat as needed.

For Metal Marks:

Make a paste with baking soda and hydrogen peroxide.
Gently spread the paste onto the metal mark using a soft cloth or sponge.
Let it sit for 5-10 minutes.
Rinse and dry thoroughly.
Avoid scrubbing too aggressively on metal marks to prevent dulling the surface.

For Hard Water Stains:

Mix equal parts white vinegar and warm water.
Dip a soft cloth into the solution and wring out excess liquid.
Let the cloth sit on the stains for a few minutes.
Scrub gently in a circular motion and rinse thoroughly.
Dry completely with a soft cloth.
Repeat as needed for stubborn buildup.

For Mold and Mildew Stains:

Mix a few tablespoons of bleach into 1 cup of warm water.
Dip a stiff nylon brush into the solution.
Gently brush the affected areas using light, circular scrubs.
Let the solution sit for 5 minutes before rinsing thoroughly.
Allow the surface to dry completely.

Tips for Preventing Stains on Quartz

Good cleaning habits and prompt stain removal can keep quartz looking like new. Here are some handy tips for prevention:

Wipe up spills immediately, especially oils, wine, and acidic liquids. The quicker you act, the easier stains can be removed.
Use cutting boards and trivets to protect the countertop from scratches and heat.
Clean quartz regularly using a stone cleaner and microfiber cloth to remove grime before it becomes stubborn stains.
Avoid using cleaners containing lemon, vinegar or other acids. Always check product labels.
Re-seal quartz countertops every 1-2 years using a stone sealer to reinforce its water and stain resistance.
For heavy usage areas, consider applying a protective wax layer 1-2 times per month.

When to Call for Professional Help

For more stubborn stains or etching that don’t respond to home cleaning methods, professional help may be needed:

Professionals have access to stronger cleaners, equipment and polishers that can correct etching or dullness.
They can identify the type of stain or damage and match the appropriate restoration method.
Experts can evaluate if the countertop needs deep cleaning, resurfacing, or re-polishing to restore its original beauty.
Repairs are also best left to the professionals to avoid further damaging the quartz.
