Quartz countertops are popular in many homes due to their durability, low maintenance, and stylish appearance. However, like any surface, quartz can accumulate germs and bacteria over time that need to be cleaned. Here is a thorough guide on how to properly disinfect a quartz countertop.
What is Quartz?
Quartz countertops, sometimes referred to as engineered stone, are made from ground natural quartz crystals combined with resins and pigments. The resins bind the quartz particles together to create a hard, non-porous surface.
Benefits of quartz include:
- Extremely durable and scratch resistant
- Resists stains
- Easy to clean and maintain
- Available in a wide variety of colors and patterns
- Does not require sealing
However, quartz is not impervious to germs and bacteria. Routine cleaning is required to remove contaminants and prevent the spread of illness.
How to Disinfect a Quartz Countertop
Disinfecting your quartz countertops helps kill harmful germs, viruses, and bacteria. Here are the recommended steps for proper disinfection:
1. Remove Surface Clutter
Start by clearing the countertop of any items or appliances. Removing clutter prevents contaminants from spreading and allows you to access the entire surface area.
2. Clean With Soap and Water
Use a soft sponge or cloth to wash the quartz with warm water and mild dish soap. Scrub the entire countertop surface to lift up dirt and debris. Rinse thoroughly with clean water and dry with a soft towel.
3. Disinfect with an EPA-Approved Cleaner
For disinfection, use a cleaner approved by the Environmental Protection Agency (EPA) for use against SARS-CoV-2, the virus that causes COVID-19. Recommended disinfectants safe for quartz include:
- Bleach solutions
- Alcohol solutions with at least 70% alcohol
- Hydrogen peroxide cleaner
- Quaternary ammonium (Quats)
Read all label instructions carefully and follow proper contact times to allow disinfectants to fully work.
4. Apply Disinfectant and Let Sit
Spray or wipe disinfectant evenly across the entire quartz surface. Ensure the area remains visibly wet for the full contact time recommended on the product label.
5. Rinse and Dry
After the contact time is complete, rinse the countertop thoroughly with fresh water to remove any disinfectant residue. Wipe dry with a clean microfiber cloth or allow to fully air dry.
Tips for Proper Disinfection
- Disinfect high-touch areas frequently, including after food prep and before/after guests visit.
- Use a disinfectant compatible with quartz – avoid bleach solutions over 10% concentration.
- Never mix cleaning products together – this can create toxic fumes.
- Make sure to follow all product instructions to allow full contact time for disinfectants to work properly.
- Replace sponges and towels frequently to prevent recontamination.
- Ventilate the kitchen during and after disinfecting.
Alternative Disinfectants
For a non-chemical approach, steam cleaners can also be used to naturally disinfect quartz countertops. The high heat kills germs without harsh chemicals.
Vinegar is another natural disinfectant. Make a solution of 1 part white vinegar to 1 part water and wipe down the quartz. Allow the solution to sit for 5-10 minutes before rinsing.
When to Disinfect vs. Clean
Disinfection of quartz countertops should occur:
- After raw meat, poultry, or fish preparation
- After handling of any bodily fluids
- After any sickness in the household
- After guests visit, especially if sick
- On a weekly basis in high traffic areas
For routine daily or weekly cleaning, regular soap and water or a mild quartz-safe cleaner is sufficient. Disinfectants are only needed periodically or when disinfecting high-touch surfaces.
Maintaining a Sanitary Quartz Countertop
With routine cleaning and periodic disinfection using an EPA-approved, quartz-safe disinfectant, you can keep your quartz surfaces fresh and free of harmful germs. Be sure to give disinfectants proper contact time to work correctly.
Focus on high-touch areas like around the sink and stove. Allowcountertops to completely dry after cleaning. By maintaining clean and disinfected quartz countertops, you can have peace of mind your surfaces are sanitary.
