Do Black Quartz Countertops Stain?

Black quartz countertops are a popular choice for many homeowners due to their stylish appearance and durability. However, some people wonder if black quartz is prone to staining. Here is a detailed look at whether black quartz countertops stain and how to care for them to prevent discoloration.

What is Black Quartz?

Black quartz, also known as onyx quartz, is an engineered stone made from quartz particles bonded together with resin. It’s available in a deep, dark black color that creates a dramatic look.

Quartz is an extremely hard material, ranking just under diamonds on the Mohs hardness scale. This makes it very resistant to scratches, chips, and cracks. The resin binding also makes quartz non-porous, so it does not easily absorb stains.

Do Black Quartz Countertops Stain?

The short answer is yes, black quartz can stain. However, it is much more stain-resistant than many other countertop materials like marble or granite.

Here are some specifics on staining with black quartz:

  • Pigmented staining agents like wine, coffee, or fruit juice can temporarily stain the surface. However, these stains often fade over time with proper cleaning.
  • Oils and grease can cause dark spots if left to soak in. But these can usually be removed with the right quartz cleaner.
  • Harsh chemicals like paint removers, oven cleaners, and drain openers can etch or discolor the surface.
  • Prolonged heat exposure can cause permanent burns or cracks. Always use trivets and hot pads.

So in summary, black quartz is not completely stain-proof, but stains are less likely compared to other natural stone counters. With proper care and cleaning, it will retain its beautiful dark finish for many years. The key is addressing spills and stains quickly before they have a chance to set in.

How to Prevent Staining on Black Quartz

Here are some tips to keep your black quartz counters looking like new:

Use Sealers

Sealing is an optional step but can help minimize staining. Look for sealers specifically designed for quartz rather than stone sealers. Reapply every 1-2 years.

Clean Spills Quickly

Immediately wipe up food and drink spills. Don’t let them sit and soak in. For dried-on messes, use a damp cloth and a little mild soap.

Avoid Harsh Chemicals

Don’t expose your quartz counters to paint removers, oven cleaners, bleach, drain cleaners or other corrosive chemicals. They can damage the surface.

Use Cutting Boards

Always use cutting boards for food prep rather than cutting directly on the quartz. This prevents dulling, scratching and staining from knives.

Apply Heat Protection

Place trivets under hot pans and baking dishes. Never put hot cookware directly on quartz surfaces. This can cause burns.

How to Remove Stains from Black Quartz

If stains occur on your black quartz, try these cleaning steps:

Step 1 – Try Dish Soap and Water

Mix a few drops of dish soap with warm water. Use a soft cloth or sponge to gently clean the stained area. Avoid aggressive scrubbing. This may be enough to lift some staining.

Step 2 – Use a Quartz Cleaner

If dish soap doesn’t work, reach for a specially formulated quartz cleaner. Look for ones that contain solvents designed to break down stains. Follow label directions closely.

Step 3 – Consider a Poultice

For stubborn stains that resist other cleaning methods, a poultice may be required. Poultice pulls the stain out from the inside. Be very gentle to avoid dulling the surface.

Step 4 – Consult a Pro

For stains that you simply cannot remove through normal cleaning, talk to a professional stone restoration company. They have commercial-grade stain removers and polishing equipment. This should be a last resort.

Maintaining Your Black Quartz Counters

Caring for your black quartz counters doesn’t require much effort. Follow these habits to keep them looking beautiful:

  • Clean spills quickly to prevent soaking in
  • Use mild soap and water for routine wiping
  • Disinfect surfaces occasionally with an approved cleaner
  • Avoid exposing quartz to corrosive chemicals
  • Use trivets and cutting boards to prevent damage
  • Reseal every 1-2 years with a quartz-safe sealer

Can Stains Be Removed from Black Quartz?

In most cases, stains can be removed from black quartz counters with the proper cleaning methods. Light surface stains usually come out with mild soap and water. For more stubborn stains, use a specialized quartz cleaner formulated to break down and dissolve the pigment.

Deeply set-in stains may require help from a professional stone restoration company. With the right tools and commercial cleaners, they can remove stains without damaging the quartz.

However, if the stain remains after extensive cleaning, replacement of the affected quartz may be required. But this would be extremely rare, as black quartz is highly stain-resistant. Prompt cleaning when stains occur gives the best results.

Is Black Quartz Prone to Scratching and Etching?

Black quartz has excellent scratch resistance due to its hardness. It rates 7 out of 10 on the Mohs hardness scale, much higher than materials like marble (3) and limestone (4). So it does not scratch as easily.

However, black quartz can become dulled over time with regular use. Its dark color also shows marks readily. Avoid using abrasive scouring pads, which can leave light scratches. Etching can occur from prolonged exposure to acidic foods like lemon juice. Use cutting boards to protect the surface.

What is Better for Stain Resistance: Black Quartz or White Quartz?

Both black and white quartz have outstanding stain resistance compared to other countertop materials. Neither color is necessarily better or worse when it comes to rejecting stains.

However, black quartz does have one disadvantage – stains tend to be much more visible against its dark backdrop. For example, a coffee stain is easy to see on black but could blend into white or gray quartz.

So for this reason, some homeowners prefer lighter quartz colors if maximum stain concealment is the priority. But both options are far superior to granite, marble, and other porous natural stones when it comes to stain protection.

Is Black Quartz Good for Kitchen Countertops?

Black quartz is an excellent choice for kitchen countertops. Its advantages include:

  • Stylish, dramatic appearance that makes a design statement
  • Extremely durable and scratch-resistant surface
  • Non-porous so resists staining and won’t harbor bacteria
  • Easy to clean and maintain
  • Never needs sealing
  • Resilient to heat, cuts, and impacts
  • Long-lasting with a lifetime of 25 years or longer

The only downside is that stains on black quartz are quite visible. Frequent wiping and prompt cleanup of spills prevents this. Overall, black quartz provides an elegant, user-friendly, and low-maintenance countertop option.


While not completely immune to stains, black quartz counters are highly stain-resistant with proper care. Their non-porous composition prevents absorption of most spills. Simple cleaning techniques can remove most stains that occur on the surface. For stubborn spots, specialized quartz cleaners break down and lift away the staining. With prompt cleanup of spills, black quartz counters will retain their like-new beauty and color. Using trivets, cutting boards, and sealers further improves stain resistance. Black quartz is a refined, durable, and reliable surface that is ideal for kitchens and bathrooms.
