Does Calacatta Quartz Stone Countertop Stain?

Calacatta Quartz is used a lot due to its stain and scratch resistant qualities. Quartz is very durable and easy to maintain. This gives the opportunity to use this material in many places, including bathrooms, kitchens, restaurants, etc.

Why Quartz Is Stain-Resistant, Not Stain-Proof?
Quartz is engineered to be a superior alternative to popular countertop choices such as granite.  its composition is of 90-95% quartz crystals, the rest is made out of resins that bind the particles together. These resins are the key to why quartz is superior to natural stone in some aspects. To this effect, one of its advantages is its low rate of absorption, which it owes to the resin binders used during the manufacturing process.  

The permanent seal of quartz is not completely impenetrable
While homeowners do not have to worry about sealing their quartz countertops, this does not mean stains will not form from time to time. Hard water and tea stains on quartz surfaces are fairly common, but since they do not penetrate as deep as unsealed natural stone, they are easier to remove.    
 When it comes to stains, the resins mostly make quartz more resistant to them, however, there is a catch. They open up possibilities for other kinds of stains.  
You see, natural stones stain because they are porous. Thus, liquids can penetrate them and get stuck there forever. For that reason, we seal natural stones from time to time.  
Now, quartz is more resistant to stains and requires no sealing, because the resins create a virtually non-porous surface. Therefore, there is no penetration of liquids. Quartz won’t ever get marks like those of unsealed marble, who is stained even by water.

Removing Stains from Quartz Countertops
These resins can react to chemicals, such as alkaline cleaners, high pH detergents, or specific kinds of acids. The result of these reactions is discoloration, white or bleached stains.  
Unfortunately, that’s not the only way quartz can stain.    
Any spill that leaves a mark after being wiped down will require scrubbing with a non-abrasive cleaning pad and a generous amount of quartz cleaner. If the stain is caused by paint, nail polish, lipstick, wax, or food that has dried and formed a crust, scraping with a plastic knife or spatula should make the stain removal process easier.

Preventing Quartz Stains and Discoloration
If spills happen, wipe them out and clean them as soon as possible.  That brings us to the second barrier of prevention.
Prevent direct contact with the quartz surface at all times. Be cautious with your countertops, don’t ever leave them wet, use cutting boards and pot holders to protect them.
Heat and sunlight exposure will discolor your surfaces, don’t let it happen.
