Quartz countertops are popular options for kitchens and bathrooms due to their durability, stain resistance, and stylish appearance. However, while quartz is less porous than natural stone and generally does not easily stain, it is still possible for some stubborn stains to occur over time. Removing stains from quartz requires using the right techniques and cleaners to avoid damaging the countertop surface. With some care and effort, it is possible to get quartz looking like new again.
What Causes Stains on Quartz?
Quartz is made from ground quartz aggregate blended with polymer resins. This makes it nonporous, so spills and stains have difficulty penetrating the surface. However, certain materials can still stain quartz if left for prolonged periods:
- Oil-based products like cooking oils, grease, and cosmetics
- Pigmented liquids like coffee, tea, wine, and juice
- Harsh chemicals like paint removers, oven cleaners, and drain openers
- Foods with strong pigments like curry powder, turmeric, and berries
Stains also tend to build up in grout lines and rough areas on the countertop over time. High heat and direct sunlight can also discolor quartz. With proper care and cleaning, most stains can be prevented or removed before they have a chance to set in and permanently stain the quartz.
Cleaning vs. Stain Removal for Quartz
It is important to understand the difference between routine cleaning and stain removal when it comes to caring for quartz:
Cleaning: This involves quick daily wiping and cleaning spills as they occur. A mild soap and water solution is typically sufficient for regular cleaning. This prevents buildup that leads to stains.
Stain removal: This refers to dealing with set-in stains that require more effort to lift. Stain removal may require specialized cleaners and techniques depending on the type of stain.
Quartz requires minimal regular cleaning due to its low maintenance nature. But when stains do occur, specific stain removal procedures are needed to avoid permanently damaging the surface.
How to Remove Common Stains from Quartz
Here are some tips for removing the most stubborn stains from quartz countertops:
Oil-Based Stains
- Kitchen oils, grease splatters, cosmetics, and mineral oil can leave behind oily residues.
- Use a degreasing cleaner made specifically for stone and quartz. Spray it on and let it sit for 5 minutes.
- Scrub with a soft cloth or nylon brush. Rinse thoroughly and dry.
- For tough oil stains, use an absorbent such as flour or chalk to draw out the grease, then rinse.
Coffee and Tea Stains
- Coffee, tea, sodas, and other drinks can stain quartz.

Dried or Caked-On Spills
- For dried messes that have hardened on the countertop:
- Soak the area with hot water to soften the spill.

- For heavier stains, make a poultice using vinegar, flour, and hydrogen peroxide. Apply to the stain and cover in plastic wrap.
- Let sit for 4-6 hours, then rinse thoroughly. Scrub with a soft cloth.
Hard Water Stains
- Mineral deposits from water can build up and stain quartz.

When to Call a Professional for Quartz Stains
If stains persist after numerous cleaning attempts, or if the stain has etched or damaged the quartz surface, it’s best to call in a professional:
- Quartz restoration specialists have commercial-grade stain removers and tools for deep cleaning and stain removal. This is recommended for tough stains that have set into the surface.
- Quartz fabricators can examine the damage and determine if the stain can be removed or if the quartz needs to be refinished or replaced. Refinishing involves mechanical polishing to remove layers of quartz until the stain disappears.
- Counter installers can remove and replace sections of quartz if the stain damage is severe. Seam lines between new and existing sections can be quite subtle with professional installation.
Professionals have access to the strongest stain removal methods that are not available to the average consumer. Getting expert help can prevent further damage from improper cleaning attempts.
Stain Removal Tips and Tricks
- Always start with the gentlest method first, like soap and water. Move up to stronger cleaners only if needed.
- Apply cleaners and let them sit and work for 10-15 minutes before scrubbing and rinsing. Don’t immediately wipe.
- Use a toothbrush or soft nylon brush for scrubbing stains in textured areas and grout lines. Avoid stiff scrub brushes.
- For oil-based stains, sprinkle cornstarch, flour, or chalk on the stain to absorb excess grease, then wipe away.
- After cleaning, rinse twice with clean water to remove all cleaner residues which can re-stain quartz.
- Consider resealing your quartz every 1-2 years to boost stain resistance and ease cleaning.
FAQs About Removing Stains from Quartz
Can I use bleach or abrasives to remove stains from quartz?
No, avoid using bleach, scouring pads, or abrasive cleansers on quartz as they can damage the surface. Always use cleaners specifically formulated for quartz and apply gently with a soft cloth or brush.
What happens if I accidentally stain my quartz?
Don’t panic! Many stains can be removed with the proper cleaning methods. Start with a mild cleaner and gentle scrubbing. For tough stains, use a poultice method. Getting stains professionally removed is an option for severe staining.
How can I prevent stains on my quartz countertops?
Clean spills immediately before they have a chance to set in. Use cutting boards, trivets, and coasters to protect the surface. Apply sealers every 1-2 years. Clean regularly with mild soap and water.
Why do some stains keep reappearing on my quartz?
