Quartz countertops are a popular choice for many homeowners due to their durability, aesthetics, and low maintenance. However, like any surface, quartz countertops require regular cleaning to keep them looking their best. When choosing a disinfectant for quartz, it’s important to select a product that is safe for the material and effective at eliminating germs and bacteria. Here is a detailed guide on how to safely disinfect quartz countertops.
What is Quartz?
Quartz countertops, often referred to as engineered stone, are made from ground natural quartz crystals combined with resins and pigments. The exact composition varies between manufacturers, but quartz typically makes up over 90% of the slab. The resins bind the quartz particles together to form a durable, non-porous surface.
Compared to natural stone like granite, quartz is less prone to staining, etching, and damage. It does not require annual sealing like granite. This makes quartz an ideal low-maintenance countertop for busy kitchens.
How to Clean Quartz Countertops
For regular cleaning, quartz can be wiped down with a soft, damp cloth or sponge and a mild soap or detergent. Avoid abrasive cleaners or scrubbing pads, which can dull the surface.
Here are some best practices for keeping quartz clean:
- Wipe up spills immediately, especially acidic substances like juice, vinegar, and wine which can etch quartz.
- Rinse the surface thoroughly after cleaning. Detergent residue left behind can eventually cause buildup.
- Blot dry with a paper towel or soft cloth. Avoid letting water pool and air dry, which can lead to water spots.
- For a streak-free shine, use a squeegee to wipe the countertop after cleaning.
- Clean the entire surface 1-2 times per week for an evenly maintained appearance.
How to Disinfect Quartz Countertops
To kill germs and bacteria, the quartz surface should be periodically disinfected beyond regular cleaning. However, it’s important to choose the right disinfectant that won’t damage the material. Here are the best options:
Diluted Bleach Solution
A simple mix of 1 part regular bleach to 20 parts water makes an effective disinfectant for quartz. The key is dilution – straight bleach can damage and discolor the surface.
To disinfect with diluted bleach:
- Mix 1⁄3 cup bleach per gallon of cool water.
- Wear gloves when handling bleach.
- Apply the solution with a clean cloth, carefully avoiding seams and edges.
- Let it sit for 5-10 minutes before rinsing thoroughly.
- Allow to air dry. Never mix bleach with other cleaners.
Hydrogen Peroxide
As a milder alternative to bleach, hydrogen peroxide is generally safe for disinfecting quartz counters. Use a 3% solution and allow it to sit for 1-2 minutes before wiping clean with water. This breaks down into just water and oxygen.
Rubbing Alcohol
For spot disinfecting smaller areas of a quartz countertop, rubbing alcohol is a fast-acting option. It should be diluted with water at a 1:1 ratio. Apply it to the surface and wipe clean after 60 seconds.
Vinegar
Though not as potent a disinfectant as other options, white vinegar can help kill some germs and viruses. Mix a 1:1 solution of vinegar and water and spray onto quartz. Allow it to sit briefly before wiping thoroughly with a damp cloth. Avoid prolonged exposure to prevent possible etching.
Professional Disinfectants
Look for EPA-registered disinfectant products specifically labeled as safe for quartz and stone surfaces. Popular options like Lysol and Clorox wipes work well. Always carefully follow the manufacturer’s instructions.
What Not to Use on Quartz Countertops
Certain cleaners and disinfectants are unsuitable for quartz and can lead to permanent damage:
- Avoid any product containing lemon, vinegar or other acids. This can etch the finish.
- Do not use abrasive pads, scrubbing brushes, or powders.
- Skip ammonia-based cleaners, which can discolor quartz.
- Steer clear of harsh chemicals like paint removers, drain cleaners, etc.
- Never mix bleach and ammonia, which creates toxic fumes.
Tips for Disinfecting Quartz Countertops
- Minimize moisture exposure time by rinsing surfaces after the recommended contact time.
- Use a soft microfiber cloth rather than paper towels to avoid scratching.
- Spot test cleaners and disinfectants on an inconspicuous area first.
- Reseal quartz once a year with a specialty quartz sealer for added protection.
- Increase frequency of disinfecting high traffic areas like around the sink.
- If discoloration occurs, have a professional refinish the quartz. Avoid DIY stain removal.
Maintaining a Sanitary Quartz Kitchen
With the proper care, quartz countertops can stay looking clean, hygienic and structurally sound for decades in the busiest kitchens. Be sure to thoroughly disinfect high-touch areas like countertops, cabinets knobs, appliance handles, and sink fixtures regularly. This prevents the spread of bacteria and viruses through shared spaces. Consult a quartz care guide for ideal cleaning frequency and methods tailored to your specific use and traffic.
Frequently Asked Questions About Disinfecting Quartz Countertops
Can I use rubbing alcohol to disinfect my quartz counters?
Yes, rubbing alcohol is generally considered safe for disinfecting quartz surfaces. Dilute it 1:1 with water and apply for 60 seconds before wiping clean with a soft cloth. Avoid prolonged exposure.
What strength hydrogen peroxide can be used on quartz?
A mild 3% hydrogen peroxide solution is recommended. Stronger concentrations could potentially damage quartz. Always spot test first.
How often should I disinfect a quartz countertop?
High traffic areas like around the kitchen sink should be disinfected 1-2 times daily. Disinfect the entire surface at least once weekly. Increase frequency after food prep and high usage.
Is Lysol or Clorox wipes safe for quartz?
Yes, Lysol, Clorox, and other major brand disinfecting wipes are considered safe choices for quartz when used properly. Check that they are EPA-registered for use on stone surfaces.
Can I use vinegar to disinfect a quartz countertop?
Vinegar is not the strongest disinfectant but can have some sanitizing effect. Mix equal parts vinegar and water and limit contact time to avoid possible etching. Rinse thoroughly after.
What happens if you use the wrong cleaner on a quartz countertop?
Harsh chemicals, acidic and abrasive cleaners can damage quartz. This includes etching, discoloration, loss of shine, and deterioration of the surface. Always verify compatibility first.
How can I remove stains or discoloration from my quartz countertop?
For minor stains, consult your quartz manufacturer’s care guide for stain removal. For significant damage or etching, professional refinishing or replacement may be needed. Avoid DIY stain removal.
Conclusion
Regular cleaning and disinfecting are key to preserving the look and longevity of quartz countertops. With the right practices, quartz can withstand years of use while inhibiting bacteria growth. Diluted bleach, peroxide, alcohol, and vinegar solutions make excellent chemical-free options. Always spot test cleaners first and avoid abrasive products. Disinfect high traffic areas frequently for a sanitary, healthy kitchen environment. Follow the manufacturer’s care instructions for your specific quartz material.
