Disinfecting Quartz Countertops? Do This, Not That!
With its sleek, modern aesthetic and durable construction, quartz is a wildly popular choice for kitchen and bathroom countertops in homes across the country. But like any surface, quartz requires proper care and cleaning methods to prevent the spread of germs and maintain its flawless finish over time.
In the age of COVID-19 and increased focus on disinfection, understanding the right techniques to sanitize quartz countertops without causing damage is more crucial than ever. Read on as we detail fail-safe methods for keeping your quartz hygienic while avoiding common mistakes that could compromise its beauty and integrity.

Why Proper Disinfection of Quartz Countertops is Crucial
As engineered stone composed of ground quartz particles held together by polymer resins, quartz offers an ideal environment for germs and bacteria to multiply if not properly disinfected. Viruses deposited by unclean hands, spills, or food prep can survive on quartz surfaces for extended periods.
With quartz countertops being focal points in two of the most bacteria-prone areas of homes, the kitchen and bathroom, a regular disinfecting regimen is vital. Not only does this prevent illness, it also avoids permanent stains or etching that can occur from prolonged exposure to grime buildup.
Quartz Popularity for Modern Kitchens and Baths
Thanks to its durable, low-maintenance, and stylish profile, quartz has surged ahead as the countertop material of choice for renovated kitchens and bathrooms. But some homeowners may be unaware of proper techniques for keeping these surfaces clean.
Role of Proper Disinfection Amid COVID-19
The pandemic has highlighted the importance of disinfecting high-touch areas of the home. While quartz's non-porous properties limit penetration of viruses, following CDC guidelines for cleaning stone surfaces is still advised.
Preventing Buildup of Bacteria and Viruses
Germs and viruses deposited on quartz can survive up to days or weeks if left unchecked. Simple daily cleaning helps prevent gradual accumulation of microbes over time in a "clean enough" approach.
Common Cleaning Mistakes to Avoid
When attempting to disinfect quartz countertops, some well-intentioned cleaning methods can actually have detrimental effects.
Using Bleach or Ammonia Products
While bleach solutions may seem like an obvious disinfectant, the harsh chemicals can actually degrade the resin binders that hold quartz together, damaging the structural integrity of the stone.
Letting Spills Sit for Prolonged Periods
Be diligent about wiping up spills when they occur rather than letting them sit. Prolonged moisture exposure can lead to warping or discoloration damage of quartz surfaces over time.
Neglecting to Regularly Disinfect
Cleaning quartz only when visibly dirty fails to address gradual microbial buildup. Follow a consistent regimen of daily or weekly disinfection.
Best Practices for Disinfecting Quartz
Keep quartz counters safe from germs without risking harm to the material itself using these methods:
Daily Cleaning Regimen
Plan to thoroughly clean and disinfect all quartz surfaces at least once per day or straight after food preparation using a quartz-safe antimicrobial cleaner.
Soft Cloth/Brush to Avoid Scratches
Gently scrub the disinfectant over the entire surface using a soft cotton cloth or brush. Never use abrasive pads that could scratch quartz.
Isopropyl Alcohol Solution Application
Spray a 70% isopropyl alcohol solution mixed with a small amount of mild dish soap over quartz then let sit briefly before wiping.
Thorough Scrubbing, Rinsing, and Drying
Agitate the disinfectant thoroughly over the surface, rinse completely with water, then dry with soft cloth to prevent moisture damage.
Recommended Frequency of Disinfection
- At least once daily
- After preparing raw meats on counters
- Anytime someone ill has been around the counters
Setting reminders can help maintain a consistent quartz cleaning routine for optimal germ prevention in busy households.
Indications Your Quartz May Need Resealing
While quartz itself is non-porous, sealers provide an added layer of protection against stains and microbes. Signs it may be time to reapply sealer include:
Appearance of New Stains
If new stains start appearing that cleaning alone cannot tackle, the sealer has likely worn off in spots.
Changes to Surface Smoothness
If parts of the once-silky quartz take on a rougher feel, sealer restoration could be needed.
Accumulation of Difficult Grime
If regular cleaning fails to combat gradual buildup of grime in cracks and crevices, resealing is advised.
Quartz-Safe Disinfectants to Use
When selecting disinfecting products for quartz, stick to these safe options:
Store-Bought Quartz Disinfecting Cleaners
Seeking out cleaners specifically formulated for quartz surfaces ensures a non-damaging solution.
Diluted Isopropyl Alcohol Solutions
A diluted isopropyl alcohol and water solution makes an effective DIY disinfectant.
NON-Acidic, NON-Abrasive Formulas
Ensure any cleaner contains no acidic ingredients like vinegar or abrasives that could etch quartz.
Step-By-Step Disinfection Process
Follow these fail-safe steps for quartz disinfection:
- Mix isopropyl alcohol solution according to package instructions
- Spray solution liberally over entire surface
- Allow to sit on quartz for 30-60 seconds
- Gently scrub entire surface with soft cloth
- Rinse thoroughly with clean water
- Dry completely with microfiber towel
Maintaining Quartz Countertop Condition
Proper cleaning is just one aspect of long-term quartz care. Also advise:
Avoid Direct Sunlight Exposure
Position quartz out of direct sunlight to prevent possible discoloration from UV light over time.
Deal with Spills Immediately
Promptly wipe up spills as they occur to prevent possible staining issues.
Reapply Sealer Every 6-12 Months
Refresh protective sealers periodically based on usage levels to guard against microbes.
When to Call in a Professional
In certain cases, it's best to enlist professional assistance with quartz care:
For Heavy-Duty Grime Removal
If stains or buildup persist despite aggressive cleaning efforts, a pro may be needed.
If Damage Like Scratching Occurs
Consult a fabricator right away if physical damage happens so it can be assessed and repaired.
Experts can best evaluate if sealers are still fully intact or require replacing.
You can keep your countertops germ-free for years with the help of this guide. Just be sure to always reach for the quartz-approved cleaners and not harsh chemical concoctions. Gentle, thorough disinfection is key!
