Sudden changes in temperature can cause the Quartz to crack which is why high heat appliances used in the bathroom such as hair straighteners or curling wands must be placed on heat resistant mats- often sold with the product.
Overall, quartz has a strong heat resistance and won't change shape or color when exposed to routine heat. Still, excessive and prolonged countertop heat can damage quartz, so you'll want to use a trivet or pad between the countertop and any hot cookware or heat source, such as electric frying pans or curling irons.
For quartz countertops in the bathroom, be especially careful with curling irons and straightening plates. Any hot part of these hair tools can leave scorch marks on the counter. Make use of spoon rests or a stylish trivet-like mat in the bathroom so there's always a safe place to put the curling iron.
Quartz countertops are made with up to 90% quartz. The rest of the material is pigments and resin. Since the resin can only withstand approximately 150 degrees, placing very hot materials such as a pan directly out of the oven will burn the countertop and cause permanent damage.
Abrasive cleaners and scrubbers such as Comet or Scotch-Brite are not recommended, as they can scratch the smooth surface of quartz. The best way to care for your quartz is to prevent damage before it occurs. Use trivets or potholders under hot pots and pans to avoid heat discoloration.
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.
Clorox wipes should never be used to clean your quartz countertops because the solution used in the wipes can potentially damage the surface. Instead, use warm water and mild soap, white vinegar and water or a quartz cleaner.
Your coffee pot, a bowl of soup, or mug of hot tea won't damage quartz surfaces.
Avoid using both alkaline and acidic cleaner because they will break down the bonds between quartz and resin and cause long-term damage to the surface. Harsh and acidic cleaning agents such as vinegar, lime, lemon are going to erode the sealant of the countertops' surface over time.
You Can't Set Hot Pans on Them
Although quartz countertops are extremely durable and considered heat-resistant, putting a hot pan right on the surface can damage the material. As with most other countertops, you'll need to use a trivet or stove mitt to protect it, as heat can cause discoloration and/or cracking.
Baking Soda + Water
Baking soda will chemically absorb the rust stain, leaving your quartz countertops safe and clean. Step 1: Mix equal parts baking soda with equal parts water until it has a paste-like consistency. Step 2: Apply the baking soda paste to the affected area and let sit for 10-15 minutes.
Unfortunately, the polyester resin in quartz can be easily damaged by heat from the toaster oven, electric frying pan, oven, crock pot, or any other appliance that produces a lot of heat.
Once installed, you can expect your quartz countertops to withstand heat up to about 300 degrees Fahrenheit. If exposed to temperatures above this range, the resin binders within the quartz slab can change their chemical state — often impacting the color of the quartz.
Solid surface.
Quartzite materials are incredibly durable and low-maintenance. Scratches are easily buffed out with fine-grade sandpaper, and the surface can handle high heat (curling irons and all). The cost is comparable to granite and marble.
The Weaknesses of Engineered Stone – Quartz
Unlike granite, engineered quartz is not really heat-resistant, not to mention that it is also susceptible to crack or chip if it experiences a heavy impact close to the edge. The product is not ideal for fireplaces or outdoor use.
Dwyer quartz countertops are some of the most wear-resistant on the market. They are also heat, stain, impact, and scratch resistant.
Windex is considered a base and has a pretty high pH level, which means it could be damaging to quartz. Some cleaners say it's okay to use in small quantities, while others warn against it. For the safest and most sure option to keeping your quartz clean, skip Windex and opt for a mild cleaner like dish soap.
If you have a quartz countertop, you should be able to use Dawn Dish Soap without any issues. However, if you notice any discoloration or staining, you might need to switch to another brand of dish soap.
This will dull the finish of your countertop. Chemicals such as drain cleaners, paint strippers, or products containing Hydrofluoric acid, Methylene chloride, or trichloroethylene will also discolor quartz countertops. You can use the same sponge and circular scrubbing motions as you would for cleaning water stains.
Placing Hot Appliances on Your Countertop. While quartz may be highly heat-resistant, prolonged exposure will damage the resin causing it to discolor. Temperatures above 300° F can spell bad news for your countertop. Besides, sudden extreme changes in temperature may lead to slab cracking.
Use Trivets and Mats
If you put hot objects such as pots or pans on the counter, it may break the fabricated quartz's seal and lead to an array of other problems. Make sure you protect the work surfaces by using trivets and mats under any hot object.
If you spill any coffee, fruit juices, tea, or wine on your countertop and it sits for a while, leaving a stain, then try mixing baking soda and warm water together. Lightly scrub the surface with the paste and a soft cloth.
The safest daily cleaner for your quartz is dish soap. But you can use any mild PH-neutral cleaner without issue. To keep your counters in good condition, put potholders down before placing hot pans on the counter, clean the counters daily, and address spills as fast as possible.
Windex, or other window and mirror shining products, are excellent for polishing quartz countertops. Spray from a distance and wipe them with a microfiber cloth. A few cleaning products in your home are not suitable for quartz countertops. Anything with high acidity or alkaline levels can cause etching.
Vinegar is very acidic and can cause the quartz to discolour or disintegrate.
