Quartz countertops are popular in kitchens and bathrooms thanks to their durability, aesthetics, and low maintenance. However, even quartz can develop dull, cloudy spots over time. The good news is that with the right techniques and products, you can restore the shine and luster to your quartz countertops.
What Causes Dull Spots on Quartz?
There are a few common culprits behind dull spots on quartz:
- Etching – Acidic spills like juice, vinegar or harsh cleaners can etch or damage the surface over time, creating dull patches.
- Hard water spots – Mineral deposits from tap water can leave behind cloudy spots as the water evaporates.
- Soap scum buildup – Residue from soapy cleaners can accumulate and create hazy, dull areas.
- General wear and tear – Normal use can gradually dull the surface of quartz countertops. High traffic areas tend to lose their luster faster.
How to Remove Dull Spots from Quartz Countertops
Here are the best methods for restoring shine and getting rid of dull spots on quartz:
Clean with a pH-Neutral Quartz Cleaner
- Use a high quality, pH-neutral cleaner made specifically for quartz. Look for brands like Granite Gold or Method.
- Spray directly onto dull areas and wipe clean with a soft cloth. PH-neutral cleaners help remove built-up grime and soap scum.
Make a Baking Soda and Water Paste
- Mix a paste of baking soda and water and apply to dull spots with a soft cloth or sponge.
- Let it sit for 5 minutes before scrubbing in a gentle, circular motion. Rinse well.
- Baking soda has mild abrasive properties to lift dirt while being safe for quartz.
Try a Vinegar Rinse
- Mix equal parts white vinegar and water in a spray bottle. Spritz onto dull areas.
- Allow to sit for 2-3 minutes before wiping away. The acidic vinegar dissolves mineral deposits and soap scum.
- Rinse well with clean water afterwards to remove vinegar residue.
Use a Polishing Compound or Sealant
- Apply a polishing compound designed for quartz and buff in a circular motion with a microfiber cloth.
- Alternatively, use a quartz-specific sealant which can add shine while smoothing over micro-scratches.
Spot Treat Stubborn Areas
- For etched or heavily dull spots, use a poultice made with baking soda and hydrogen peroxide. Apply to area, cover with plastic wrap and let sit for up to 24 hours before scrubbing and rinsing.
Tips for Preventing Dullness on Quartz
- Always use a cutting board instead of cutting directly on the countertop.
- Clean up spills immediately, especially acidic substances like lemon juice.
- Avoid abrasive cleansers or scrub sponges which can dull the finish.
- Reseal quartz countertops every 1-2 years with a quality sealant.
- Use a trivet or hot pad under hot pans and dishes.
With some periodic polishing and care, you can keep your quartz counters looking like new and prevent buildup of dull spots. Be sure to address any etching or deterioration of the surface as soon as possible. With the right techniques, maintaining the sparkling shine of quartz is easy.
Frequently Asked Questions About Dull Spots on Quartz Countertops
Can I use bleach or abrasives to remove dull spots on quartz?
No, avoid using bleach, abrasive cleansers, or scrub pads on quartz countertops. These can damage the surface over time. Stick to pH-neutral cleaners and baking soda instead.
Will resurfacing help restore dull quartz countertops?
Professional resurfacing is not usually needed for quartz. Polishing, sealants, and DIY approaches tend to work well instead. Resurfacing is more common with natural stone.
Why does my quartz look dull even after cleaning?
If dullness persists after cleaning, try a vinegar rinse or baking soda paste to dissolve buildup. A proper sealant can also add shine while smoothing over micro-scratches that reflect light poorly.
Can I use a Magic Eraser on quartz countertops?
Magic Erasers are too abrasive for quartz surfaces. They can end up creating even more dull spots by grinding away the finish. Use baking soda or pH-neutral cleaners instead for best results.
How can I make my quartz counters shine like new again?
Regularly clean with a quartz-safe cleaner, spot treat any etching or stubborn buildup with baking soda, and reseal the surface every 1-2 years. This keeps quartz counters looking freshly installed.
While quartz countertops are pretty low maintenance overall, dull spots can develop over time without proper cleaning and care. Etching, water deposits, soap scum, and daily wear can all gradually cloud the surface. Luckily, DIY solutions like baking soda, vinegar, and pH-neutral cleaners make it easy and affordable to restore the original shine and luster. By addressing dull areas promptly and taking preventative measures, you can enjoy sparkling quartz countertops for years to come.
