Frequently Asked Questions
Is it ok to use bleach on quartz?
No, avoid using bleach or hydrogen peroxide at high concentrations as this can damage or discolor quartz over time. Always test cleaners on a small inconspicuous spot first.
What happens if I leave a stain too long?
The longer a stain sits, the harder it’ll be to remove. Dried, caked-on stains often require more aggressive scrubbing, which can damage the quartz. Act fast to clean spills before they have a chance to set in.
Can I use vinegar to clean quartz counters?
Yes, you can safely use vinegar to clean quartz. The mild acidity helps dissolve stains and buildup. Mix with water and wipe on, rinse thoroughly. Avoid soaking the surface.
How can I make my quartz counters shine?
For extra shine, mix a couple tablespoons of olive oil with lemon juice. Wipe this solution onto the quartz, allow to sit briefly, then wipe dry with a soft cloth. The acid and oil will buff the surface beautifully.
Should I reseal my quartz countertops?
It’s a good idea to reseal quartz every 6-12 months using a silicon-based sealer made for quartz. This helps prevent stains from setting into the microscopic pores of the surface.
While white quartz countertops are fairly stain-resistant, discoloration can happen over time. By acting quickly and using the proper cleaning methods, you can often remove stains and restore the bright white luster. For stubborn stains that resist normal cleaning, call on a professional quartz cleaner to renew the surface. With proper care, white quartz countertops will maintain their beauty for many years.
