Quartz countertops are popular in kitchens and bathrooms due to their durability, aesthetics, and low maintenance. However, some quartz counters can develop clouding, a hazy or foggy area on the surface. Here is an in-depth look at what causes clouding on quartz countertops and how to prevent and remove it.
What Causes Clouding on Quartz Countertops?
There are a few potential causes of clouding on quartz counters:
Exposure to Harsh Chemicals
Quartz contains resin that binds the quartz particles together. Exposure to harsh cleaners like oven cleaners, drain cleaners, bleach, and alkaline chemicals can damage the resin and create cloudy spots. Acidic cleaners like vinegar and lemon can also etch and cloud quartz.
Moisture Damage
Excess moisture getting into the stone can cause the resin to turn white and cloudy. Damage typically occurs around the sink from frequent water exposure. Moisture can get in through cracks and seams.
Heat Damage
Exposing quartz to excessive heat can damage the resin binders. Placing hot pans directly on the counter can scorch and discolor the stone.
Physical Impact
Direct blows or pressure on the surface from heavy objects can disrupt the resin and create clouds. Quartz is durable but not immune to chipping, cracks, and marks from physical impact.
Poor Initial Installation
Shoddy installation with inadequate seam sealing can allow moisture underneath that leads to clouding and haze on the surface.
Normal Wear and Tear
General wear and tear over time can deteriorate the finish and cause clouding on older quartz counters.
How to Prevent Clouding on Quartz Countertops
You can minimize the risk of clouding on quartz surfaces by:
- Using only quartz-safe cleaners like soapy water, vinegar, or stone cleaners. Avoid harsh chemicals.
- Immediately drying any spills and water around the sink. Use a sealing agent on seams and edges near the sink.
- Using trivets and hot pads for hot pans. Never placing extremely hot items directly on the quartz.
- Avoiding direct sharp blows from objects on the counter.
- Having the counters professionally installed and resealing as needed.
- Gently cleaning quartz with non-abrasive sponges and soft cloths.
How to Remove Clouding from Quartz Countertops
If clouding does occur, there are a few ways to potentially remove it:
- Gently scrub with a soft cloth, warm water, and a non-abrasive cleaner made for stone.
- Use a chemical polishing compound specifically formulated for quartz to resurface and enhance the shine.
- Try re-polishing and buffing the affected areas using professional mechanical buffing equipment.
- For deep set clouds and damage, you may need to contact a pro to explore resurfacing, sanding and refinishing the quartz.
- If damage is beyond repair, the affected area of the counter may need replacement.
Tips for Keeping Quartz Countertops Cloud-Free
- Never use vinegar, lemon juice, or harsh alkaline cleaners on quartz.
- Seal quartz annually to prevent moisture damage, especially around sinks.
- Immediately wipe up spills, don’t let liquid sit on counters.
- Avoid abrasive scrub pads and powders that can wear the finish.
- Use trivets and cutting boards to protect from hot items and knives.
- Have quartz counters professionally installed and maintained.
- Inspect counters periodically and reseal any cracks or seams as needed.
Frequently Asked Questions About Clouding on Quartz Countertops
What are the most common causes of clouding on quartz counters?
The most common causes are chemical damage from cleaners, excess moisture around sinks, heat damage from hot pans, and physical impact damage from heavy objects. Poor installation can also contribute to clouding over time.
Does clouding on quartz mean the counters are ruined?
Not necessarily. Many times clouding can be removed with deep cleaning, re-polishing and refinishing the surface. But deep-set stains may mean replacement is needed.
How can I restore my quartz countertop’s shine if it has clouded?
Use a soft cloth with warm water and a specially formulated quartz cleaner. For deeper cleaning, use a chemical polishing compound or professional buffing. Severely damaged spots may need professional resurfacing.
Should I seal my quartz counters to prevent clouding?
Yes, it is highly recommended. Annual sealing, especially around sinks and edges, will help prevent moisture damage that leads to clouding and discoloration.
Is it possible to just replace sections of quartz that have clouded?
If the clouding is contained to one area, it may be possible to cut out and seamlessly replace just that section. Consult a countertop installation pro to see if partial replacement is an option.
Conclusion
Clouding on quartz counters can occur over time due to damage from chemicals, heat, moisture, impact, or inadequate installation. To minimize clouding, quartz owners should use gentle cleaners, sealants, trivets and cutting boards. Small clouded areas can often be restored through deep cleaning and re-polishing. But extensive damage may require replacement. With proper care and maintenance, quartz countertops can remain cloud-free for many years.
