Quartz countertops are an increasingly popular choice for kitchen and bathroom remodeling projects thanks to their durability, aesthetics, and low maintenance. However, while quartz is resistant to scratches, stains, and heat, it still requires proper cleaning and occasional sealing to keep it looking like new. Here is a guide on the best practices and products to clean and seal quartz countertops.
Why Seal Quartz Countertops
While quartz countertops are non-porous and do not require yearly sealing like natural stone, an initial seal after install and occasional sealing thereafter can offer extra protection and keep surfaces looking pristine. Here are some key reasons to seal quartz:
- Creates a protective barrier against liquids and oils from penetrating the surface
- Minimizes staining from spills like wine, coffee, and cooking oils
- Makes cleaning easier by preventing buildup of residue
- Retains the glossy, like-new shine
- Prolongs the life of the countertops
Sealing is especially important for kitchen countertops where cooking oils, spices, and other staining substances are common. For low maintenance bathrooms, sealing is often only needed every few years.
How to Seal Quartz Countertops
Sealing quartz countertops is a relatively simple process, but proper products and techniques are important for good results. Here are some tips:
- Use a sealant designed for quartz like Granite Gold Sealant – avoid flimsy grocery store sprays.
- Clean the countertops thoroughly before sealing to remove any residue.
- Apply the sealer evenly according to product directions, using overlapping circular motions.
- Allow the sealer to penetrate for 5-10 minutes then thoroughly buff off any excess with microfiber cloths.
- A second coat may be needed for extra protection, waiting 1-2 hours between applications.
- Avoid heavy usage for 24 hours after sealing.
- Reapply every 6 months to 1 year as needed, or whenever water and oil stop beading on the surface.
Proper sealing leaves countertops resistant to staining while retaining a clear, natural look. Darkening or glossy sealants should be avoided for quartz.
Best Products to Clean Quartz Countertops
Regular cleaning is important between sealings to keep quartz looking like new. Here are some effective products safe for cleaning quartz:
Mild Soap and Water
For routine light cleaning, a mild soap like dish soap and warm water is generally all that is needed. Avoid harsh detergents.
PH-Neutral Quartz Cleaner
Specialized quartz cleaners like Granite Gold Daily Cleaner help keep surfaces clean and residue-free. Look for non-acidic, PH-neutral formulas.
Baking Soda and Water Paste
For tougher stains, a paste of baking soda and water can be used. Spread the paste and let sit for 5 minutes before scrubbing and rinsing.
Hydrogen Peroxide
A light hydrogen peroxide solution of 1 part hydrogen peroxide to 4 parts water can disinfect and help remove some stains. Rinse thoroughly after use.
Rubbing Alcohol or Glass Cleaner
For hard water spots and soap scum buildup, use a small amount of rubbing alcohol or non-ammonia glass cleaner. Rinse immediately after use.
Soft Sponge or Microfiber Cloth
Always use a soft sponge, cloth, or non-abrasive scrubbing pad to avoid scratching the quartz surface while cleaning.
What Not to Use on Quartz
Some common household cleaners and chemicals can damage quartz and should be avoided:
- Vinegar or lemon juice – acids will etch and corrode the surface
- Abrasive cleaners like Comet or Soft Scrub
- Bleach or ammonia-based cleaners
- Oil soaps
- Alkaline or pH-shifting cleaners
- Acetone
- Scouring pads, brushes, or abrasive sponges
By using the proper sealing and cleaning methods, quartz countertops can stay looking like new for many years before professional resurfacing is needed. Be sure to check the manufacturer’s care guide as well for any specific recommendations. With some basic maintenance, quartz is an excellent low-maintenance and durable surface for kitchens and baths.
Frequently Asked Questions About Cleaning and Sealing Quartz Countertops
How often should I seal my quartz countertops?
For kitchens, sealing every 6-12 months is ideal. For low-use bathrooms, every 2-3 years can suffice. Seal whenever liquids no longer bead on the surface.
Can I use Windex or other glass cleaners on quartz?
Some glass cleaners contain ammonia which can damage or etch quartz. Use ammonia-free products and rinse surfaces thoroughly after cleaning.
What is the best way to remove dried food from quartz?
Soften dried food debris with water, then gently scrape away with a plastic scraper or non-abrasive pad. Avoid using metal blades or scrapers which could scratch.
How can I make my countertops shiny again?
A good quartz polish like Granite Gold Polish applied after cleaning will help restore the original glossy shine. Avoid wax-based polishes.
Can you use rubbing alcohol to disinfect quartz countertops?
Yes, rubbing alcohol is safe for occasional disinfecting. Use a dilution of at least 50/50 alcohol to water and rinse thoroughly after use.
What happens if I use the wrong cleaner on my quartz?
Harsh cleaners like those containing acids, bleach or ammonia can etch and damage quartz. Only use recommended quartz-safe cleaners and spot test new products first.
Conclusion
While quartz countertops require less maintenance than many other surfaces, proper sealing and cleaning are still essential to keeping them looking pristine over years of use. Be sure to use specialized quartz cleaners instead of generic household cleaners, and reseal every 6-12 months with a high quality sealer made for quartz. With the proper gentle care, quartz countertops can stay looking like new for exceptional durability in kitchens and bathrooms.
