To begin with, we must understand why these dull spots appear in the first place. One of the main reasons why dull spots appear on quartz countertops is over-exposure to water.

So if you spill too much water on your countertop and you do not wipe them off immediately, then you are effectively running a big risk of creating dull spots.

Indeed, quartz countertops are made of quartz stone which has a layer of sealant on top of it to prevent the stone from getting damaged easily. Thus, when the water stays in contact with the sealant for a long time, the sealant gets damaged, causing the countertop to look old and dull.

Moreover, scrubbing on the surfaces too hard or using abrasive cleaning products also contribute to creating dull spots.

If you don’t use a microfiber towel to wipe off stains or if you use a rough cloth or a sponge, this can leave a lot of small scratches, which will then appear like dull spots and can also dull down the upper layer of stone. This, in turn, may expose the inner natural stone within.

Additionally, instead of using a chopping board to cut vegetables, some people cut food on the countertop. This way, scratches are formed. Those scratches can allow certain particles to enter the layers within quartz and create dull spots.

Furthermore, putting extremely hot pots and pans directly from the stove to the countertop can cause heat damage to the quartz countertop. The resin may also melt and leave spots as the resin solidifies again but unevenly.

1. First things first, rinse the areas of the dull spots with warm water and soap. This way, you will remove any dirt or grime that may have accumulated in that area. You may use a sponge to scrub the countertop.

2. Then pour white vinegar on the affected area. Vinegar is known to be very efficient in getting rid of stubborn stains and cloudy spots. Hence, scrubbing the affected area may help you remove the dull spots very easily.

3. You may repeat the above process until you get a satisfactory result.

4. Next, wipe the vinegar from the countertop using a wet cloth. Don’t forget to pat dry the place.

5. Then spray a bit of window cleaner liquid on the affected area. Window cleaner liquids have ammonia or ammonium hydroxide, both of which are great in removing stains and dull spots from surfaces like glass, steel, or even quartz.

6. Wipe away the liquid using a paper towel.

7. Apply a quartz countertop polishing liquid to get a shinier result. Polishing liquids like Simple Green Stone Polish are used to bring back luster to your countertops. You will simply have to spray the liquid on the countertop and wipe it clean using a soft cloth or paper towel.

8. Don’t forget to dry the place again. Use a hairdryer if possible!

Unfortunately, some stains are permanent, and if it’s very bothersome to you, you may have to polish your quartz countertop. This means that you will have to use diamond pads, power grinders, and so on to actually remove a surface of the quartz to reveal a newer, much more polished surface from underneath.

Clearly, it’s not an easy job, and it will be more apt if an experienced and skilled person polishes your countertop. Hence, it’s better if you hire a service provider to help you with this job.

Now, how to prevent dull spots from forming in the first place?

When a spillage occurs, immediately arm yourself with a bit of water and a bit of hand soap. Then spray a bit of water and soap onto the spillage and around it and wipe it off, but don’t make the surface fully dry yet, instead use clear isopropyl alcohol and spray it onto the area of spillage and around. Then wipe the whole thing with a dry bit of paper towel.

Do not put pots and pans directly on the countertop. Sometimes there may be stains on the bottom of them, and these stains may be food that boiled over and left a layer of soot or residue on the sides and bottom of the pan.

Do not use or put extremely sharp or rough objects directly onto the countertop. These may cause friction to form during usage or when putting them down cause scratches which can trap water, oil, or food between those scratches.


1. How to maintain the shine of quartz countertops?

When cleaning quartz countertops, use a gentle cleanser or use a cleanser that is specifically made for use on a quartz countertop. Also, make sure that your countertop is placed in an optimal place that does not expose the countertop to too much dust or sunlight.

2. What to do if I spill ketchup on my countertop and it stains?

Use a scouring pad to remove any stains resulting from food. Wet the pad and gently scrub the stain to remove it.

3. What type of cloth/sponge can I use to clean my quartz countertop?

Use a soft microfiber towel to wipe off any water, oil, or fluid. The fibers in the towel prevent small scratches on any solid surface and have been used to clean phone screens and monitors for a long time.

However, not everyone has a good quality microfiber towel; instead, what you can do is use a cotton t-shirt or a piece of cotton cloth. This is the best alternative to microfiber cloth as cotton garments are woven uniformly and are soft as they are meant to be in contact with human skin.

This will prevent small resin particles from being wiped off by rough cleaning
