Heat damage: Although quartz is heat resistant, excessive heat exposure can cause damage or discoloration to the resin binder. Chemical exposure: Harsh chemicals and cleaning agents can react with the resins and pigments in quartz, causing discoloration or yellowing.
Using the baking soda method: Tough stains
Making a paste with baking soda and water is a great way to remove stubborn stains from quartz countertops.
Sunlight. Because quartz is made using polyester resin, over time you may start to notice some discolouration - particularly in lighter coloured countertops. On average, it takes less than a year of daily sunlight for a quartz worktop to fade.
Yes, it can. However, this typically only happens if you've used indoor quartz outside or exposed the countertop to direct sunlight for prolonged periods every single day. Under normal conditions, discoloration from sunlight is relatively rare.
Quartz countertops involve a certain degree of maintenance to keep them looking their best, and it's important to know that it's possible for a quartz slab to experience discoloration over time.
When your white quartz countertop is exposed to acidic substances like acidic foods, the white quarts can start to stain on the top layer and turn a yellow color. Acidic foods like lemons, oranges, and tomatoes should always be chopped on a chopping board in order to protect the white quartz.
If a stain does occur, addressing it promptly can prevent permanent damage: Superficial Stains: For most stains, a soft cloth or sponge with water and mild detergent will suffice. For more stubborn stains, a non-abrasive surface cleaner specifically designed for quartz can be used.
For instance, depending on the trace amounts of impurities it contains, quartz may look colorless (no impurities), light pink (titanium, iron, or manganese), milky white (tiny bubbles of gas or liquid), purple (iron), yellow (iron), or brown (extra silicon).
Under ideal conditions, a high-quality quartz countertop could last 50-100 years. But most of our homes do not offer ideal conditions. A more typical lifespan is 15-20 years. With proper care and maintenance, a homeowner might be able to extend it for a few more years beyond that.
One of the most common causes is hard water buildup, which occurs when minerals found in hard water (such as calcium and magnesium) are left behind after the water evaporates. In order to prevent this from happening, it's important to clean your bathroom countertops regularly using a non-abrasive cleaner.
Quartz is low maintenance, as it does not need countertop sealing. Quartz counters do not need sealing due to their lack of porosity. Liquids and stains cannot penetrate non-porous materials because they have a built-in seal.
To go into a little more detail, pure quartz is colorless and translucent (rock crystal). But if any little microscopic bits of anything get inside the quartz as it forms, then those impurities can alter its color. All quartz is still the same chemical compound, but colored quartzes have other things inside them.
Why Does My Quartz Countertop Look So Dull? There are several reasons why your quartz countertop may have lost its shine. Daily use, cooking oil spills, and grime buildup can leave a film on the surface and dull its natural radiance.
You shouldn't be using Clorox wipes daily, or even often, on quartz countertops because they have citric acid, which can be very harsh on your counter. Long-term use could lead to discoloration of your quartz surface.
Magic eraser may also be used to fight tough quartz stains, simply wet the magic eraser and apply in gentle, circular motion. Clean the area thoroughly with water and dry with a clean towel after. For tough to fight grease residue, you may use degreasing cleaners.
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 do have a certain level of heat resistance. However, it's not as heat-resistant as granite countertops. The same thing that makes quartz countertops so strong also makes them weak when you put heat or hot cookware on them.
Do Quartz Countertops Yellow Over Time? The short answer is that high-quality quartz countertops should not yellow over time if properly maintained and cared for. However, certain factors can contribute to the yellowing or discoloration of quartz countertops.
Harsh, abrasive cleaners, pads, and sponges should be avoided since they can permanently harm countertops. Scrubbing too hard can leave a dull surface or cause superficial scratches. Oven cleansers, grill cleaners, paint removers, dishwashing detergent, and other high pH cleaners should not be used on quartz surfaces.
Clear quartz is generally not heat-resistant and can crack or even shatter when exposed to direct, intense heat. Quartz can withstand moderate heat, but if it is subjected to rapid temperature changes or extreme direct heat, it may undergo thermal shock, causing it to crack.
Many people use Windex® or similar cleaners to help shine their countertops, while this is okay for most quartz, you should avoid cleaners with bleach or ammonia. Windex®, for example, comes in an ammonia-free version. The real key to caring for quartz is to be gentle.
Irradiation and heat treatments can create numerous colors in some, but not all, clear quartz pieces. The color range depends on the stones' sources and the specific treatments. Gemologist Mark Liccini shares his procedures and the results of his experiments with quartz color treatments.
Use a baking soda paste. Baking soda is a gentle abrasive that can help to scrub away hard water stains. Mix baking soda and water to form a paste. Apply the paste to the stain and scrub with a soft brush.
Tea, coffee or fruit juice can stain quartz worktops if left for too long. To remove the stain, use a three parts baking soda, one part water solution. Apply the solution onto the countertop and let sit for a few minutes, after which you can gently rub with a soft cloth and wipe away.
Harsh and acidic cleaning agents such as vinegar, lime, lemon are going to erode the sealant of the countertops' surface over time. This will make the surface more likely to stain.
