Discovering stains on your elegant quartz countertop can be worrying. Fortunately, quartz countertops exhibit high stain resistance but they are not completely stain-proof. Food substances such as turmeric or food dyes may cause moderate to very faint staining on quartz countertops. Fortunately, it is possible to remove stains from quartz countertops. 

Why quartz may stain though it’s stain-resistant  

Quartz countertops are made from two primary materials: polymer resins and natural quartz. It’s the natural quartz that’s impervious to liquids, impermeable to gases, and non-reactive.  

The polymer resins (about 5% to 10% in volume) bind the quartz particles. But under certain conditions, polymers may undergo slight chemical transformations. This may occur, for instance, if you leave a harsh chemical on the quartz countertop for an extended time.  

Slow reactions may result in staining. This may sound alarming but manufacturers use stable polymers with high chemical resistance, making the countertops safe for food preparation. The quartz is unlikely to stain because it’s hard and non-porous.  

Here are 7 methods for removing stains from quartz countertops. 

Seven ways to remove stains from Quartz countertops  

Can’t seem to remove those stubborn stains from your quartz countertop? Here are some of the best methods to try: 

  1. With glass cleaner 

Most glass cleaners don’t leave any streaks or smears on the surface. They also dry quickly. Products such as Windex, are not likely to damage bonds between quartz and the resin. Some also dissolve grease, and lift dirt from the surface.  

  1. DIY: White vinegar and water 

You can remove stains with supplies you already have in your kitchen. A mixture of white vinegar and water is a popular household cleaner to rid of tough stains like hard water spots from faucets, stains on surfaces, and others.   

The acidic property of vinegar makes it ideal for breaking down all types of stains.  

When preparing the mixture, use this easy formula: equal parts water and vinegar. Allow the solution to sit on the stained surface before wiping with a cloth. For stubborn stains, leave the solution to soak overnight.  

This is among the best natural methods for cleaning your quartz countertop. 

  1. Try using regular cleaners and dishwasher soap 

Sometimes an all-purpose cleaner can work on quartz stains with a little patience. Just spray your regular cleaner on the stain. Give it some time to work and buff it out. Repeat this process until the stain is removed. 

Cleaning methods that are okay to use with some care 

  1. Scouring powder  

The most popular scouring powder is Bar Keeper’s Friend, manufactured in 1882. It’s used to clean cookware, sinks, backsplashes, non-stone countertops, stoves, and other surfaces.  

It’s easy to use. Just sprinkle on a wet surface and rub gently with a damp cloth.  

When working with quartz countertops, Bar Keeper’s Friend advises against leaving the product for a very long time or over-applying in a small area.    

  1. Soft Scrub Gel with Bleach 

Soft Scrub Gel with Bleach is a great option for removing tough stains. Just be sure not to leave the product sitting on your countertop for a very long time as any acidic cleaning substance can cause discoloration when not used properly. 

Get help from a professional for deep stains 

How will you know when to get professional help? Some stains may be impossible to remove with regular cleaners. The appearance of blotches, haziness, or discoloured patches may also be a result of permanent chemical reactions.  

In such cases, it’s always advisable to reach out to the retailer where you purchased the quartz countertop. 

 

Bonus: Tips to Keep Stains off Quartz  

First line of defense against stains is becoming vigilant. That means wiping spills from the quartz countertop immediately. Don’t expose the countertop to high temperatures from hot pans. Avoid harsh cleaners that may react with the resins used for binding.  

Bottom Line  

Quartz countertops are highly resistant to stains as they are engineered stones and much easier to care for than natural stone countertops such as marble.  Still, it’s good to know that when accidents happen, you can fix them using readily-available products. 

Quartz countertops are engineered stone countertops made by combining 90% ground quartz and 8-10% resins, polymers, and pigments. Quartz is a popular choice for kitchen and bathroom countertops due to its durability and ease of maintenance. A lot of homeowners and designers also like the versatility of its color and design. Since it is man-made stone, it can come in all sorts of colors and patterns making it aesthetically suitable to any type of kitchen.

However, the most popular quartz countertops colors are of the light variety. This is because light-colored quartz countertops will suit any design and color scheme.

Do quartz countertops stain?

Quartz countertops are highly stain resistant but it is not true that they do not stain. Just like any type of countertop, quartz is vulnerable to staining from red wine, coffee, tea, tomato sauce, juice and etc. if the spills are not cleaned right away. But unlike granite (which is a natural stone), the staining does not occur because the staining liquid is absorbed by the countertop surface.

The staining occurs when the liquid reacts to the resin, which is one of the main components in quartz countertops. Resins are what help make quartz countertops non-porous but they are also what can be damaged by cleaners, heat and chemicals.

How to prevent stains on quartz countertops

The good news is stains in quartz countertop surfaces are easily preventable. Just clean the spills immediately and use protective surfaces like trays, coasters, trivets and cutting boards.

Stains can also occur on white or light-colored quartz countertops due to improper cleaning. Don’t clean your countertop using cleaners that have bleach and keep solvents such as detergent and paint thinners away from the quartz surface.

How to clean white quartz countertops

Quartz countertops might be highly stain and heat resistant but it still needs proper maintenance in order for it to keep its beauty for a longer period of time.

Regular cleaning

Quartz countertops need to be cleaned routinely:

  • Wipe with mild dish soap – Harsh cleaning agents have a high chance of reacting to the resin on the countertop surface and will cause the quartz to stain. Stay away from cleaners and use dish soaps, antibacterial soaps or hand soaps instead. Mix the soap with water and this solution will get your quartz countertop looking sparkly clean in no time.
  • Use the right cloth – Make sure that the cloth you are using to wipe your countertop is not in any way abrasive as it could permanently damage the surface of the quartz. A microfibre cloth is recommended for cleaning quartz countertops because it is highly absorbent and won’t leave watermarks.
  • Sipe spills immediately – Always clean up spills as soon as they happen. It’s always a good idea to clean up any spills before they have a chance to set up.

Extreme cases

Daily wiping your countertops and paying attention to spills will fulfill its basic needs. But once in a while, you will need to deep clean your countertop surface. Spray an ample amount of non-abrasive cleaner all over the surface and let it sit for 10 minutes before wiping away with a soft cloth.

How to remove stains from quartz countertops

No matter how much you take care of your countertops, stains are sometimes inevitable.

Most stains on quartz are due to liquid that was able to sit for too long on the surface and most experts recommend using a powder cleanser like Bar Keeper’s Friend or Bon Ami. Apply the powder on the stain and scrub with a nylon pad or brush. For mild surface stains, apply glass cleaner on top of the stain and scrub away with a non-abrasive nylon scrub pad. These methods will remove stains from quartz but won’t fix a damaged resin.

Water is made out of several minerals such as calcium or limescale. When water evaporates, these minerals are left behind creating chalky stains that won’t wipe away. Water stains are easily removed by bleach and other acidic cleaners, but as mentioned before, acidic products damage quartz surfaces and ph-neutral cleaners won’t be able to remove water stains.

The only way to remove water stains is to scrape off the deposits as much as possible with a plastic spatula. You can also use steel wool but make sure to use light handed circular motions then follow up with using a dry cloth to wipe off the loosened buildup.

Another effective way to remove water stains is to mix baking soda with water until it becomes a paste-like consistency. Then pour the mixture on the stain and rub it in with a soft cloth.

If you take good care of quartz, it will keep making you happy with its spotless look. Like this one.
