Quartz countertops are popular in kitchens and bathrooms because of their durability, easy maintenance, and stylish appearance. However, excessive heat can damage the surface and leave unsightly marks. Thankfully, there are ways to remove heat marks from quartz countertops without harming the material.
What Causes Heat Marks on Quartz?
Quartz countertops are resistant to scratches, stains, and heat up to a certain point. However, exposing the surface to extreme heat from pots, pans, and other hot kitchen tools can damage the top layer and discolor the stone.
The marks occur because the intense heat causes the resin that binds the quartz material to break down. This affects the pigment and results in light or dark burn marks on the countertop. Heat marks on quartz have blurred edges and often appear lighter or darker than the surrounding area.
How to Remove Mild Heat Marks from Quartz
If the heat mark is mild and only affects a small area, you may be able to remove it yourself using household items. Here are some simple methods to try:
Use a Mr. Clean Magic Eraser
Magic Erasers contain melamine foam that safely lifts stains without scratching surfaces. Dampen the eraser and gently rub the heat mark in a circular motion. The light abrasion can help remove discoloration from mild marks.
Make a Baking Soda Paste
Mix a few tablespoons of baking soda with water to form a spreadable paste. Apply the paste to the heat mark and let it sit for 5-10 minutes. Wipe off with a soft cloth. Baking soda is a gentle abrasive that can lift stains.
Try a Lime and Vinegar Solution
Mix equal parts lime juice and white vinegar and apply it directly to the mark. Let it sit for a few minutes before wiping clean. The acidity in this mixture helps dissolve some of the stain.
Use a Countertop Polishing Cream
Specialized polishing creams contain micro-abrasives to remove etching and light stains without damaging the finish. Rub a small amount into the mark using a soft cloth. Avoid wiping it onto unaffected areas.
Sand Lightly with Fine-Grit Sandpaper
For stubborn spots, wet a piece of 600-800 grit sandpaper and gently smooth it over the mark. The light abrasion can remove discoloration. Avoid scrubbing too hard.
Be patient and try these techniques a few times to see results. Test on an inconspicuous area first.
Removing Severe Heat Marks from Quartz
For more severe heat damage that covers a large area or leaves cracks or pits, professional help may be needed. Some options include:
Color Sanding and Polishing
A pro can perform wet sanding using extremely fine 400-600 grit paper to remove the top stained layer. They’ll then use diamond polishing pads up to 3000 grit to restore the quartz shine and richness. This abrades the minimum amount necessary.
Spot Refinishing
This involves using industrial tools to grind away the damaged section less than 1/16 inch deep. An epoxy filler gets installed and sanded until level. Finally, the pro will polish the repaired area to blend with the rest of the countertop.
Full Resurfacing
For excessive damage, the entire countertop may need resurfacing by grinding down the top layer and applying new quartz material and resin to create a fresh surface. This is the most expensive option.
Countertop Replacement
In cases where the damage penetrates deep into the slab, replacement of the entire countertop may be required. Seek quotes from countertop installers.
Professional refinishing or replacement will cost several hundred dollars or more.
Preventing Heat Damage on Quartz
The best approach is to avoid exposing quartz countertops to extreme direct heat in the first place. Follow these tips:
- Always use trivets or hot pads under hot pans, pots, baking sheets, crockpots, and other cooking equipment.
- Give the countertop time to cool before placing hot items on it after cooking.
- Don’t leave flat irons, curling irons, or other heated tools in direct contact with the quartz.
- Use a cutting board for food prep instead of chopping directly on the counter.
- Keep the surface clean to prevent any hard debris from scratching or scorching.
With proper care, quartz countertops can remain in great condition for many years before heat marks become an issue. But if stains do occur, the methods above can help remove or minimize their appearance. Handle heat marks early and carefully to restore your countertop’s beauty.
Frequently Asked Questions
What are the most common causes of heat marks on quartz countertops?
The main causes of heat marks on quartz are placing hot pots, pans, bakeware, and other kitchen items directly on the surface without a trivet. Flat irons and curling irons can also scorch if left to heat in one spot.
Do heat marks on quartz countertops go away on their own?
No, heat marks on quartz will not go away on their own over time. The discoloration is a permanent stain in the surface resin that requires active removal. Leaving the marks can allow them to worsen over time.
Can I use a magic eraser on heat marks?
Yes, Magic Erasers are safe for use on quartz counters. Dampen the eraser and gently rub in a circular motion to remove mild heat discoloration without damaging the surface. Be careful not to scrub too aggressively.
What kind of sandpaper grit should be used?
For light DIY sanding, use a 600-800 grit wet/dry sandpaper. Anything rougher can scratch the quartz. Leave heavy sanding to the professionals.
Is there a homemade solution to remove marks?
Making a paste with baking soda and water or a mix of lime juice and vinegar can help lift some mild heat stains before wiping clean. Always test on a small spot first.
Conclusion
While quartz counters are resilient, intense direct heat can still cause unsightly discoloration. Treat marks early by trying gentle cleaning methods like magic erasers, baking soda, or polishing cream on mild stains. Severe damage may need professional refinishing or replacement. Always use trivets and cuttings boards to prevent avoidable heat marks. With some care, quartz countertops will stay looking like new.
