Quartz countertops are popular options for kitchens and bathrooms because of their durability, aesthetics, and ease of maintenance. However, like any surface, quartz can become damaged over time. One of the most common issues is etching, which occurs when an acidic substance comes into contact with the countertop. The good news is that etched quartz countertops can often be repaired and restored to like-new condition with the right techniques and products.
What Causes Etching on Quartz?
Etching on quartz countertops occurs when an acidic substance reacts with the resin that binds the quartz particles together. This causes tiny pits, scratches or dull spots on the surface. Some common household items that can lead to etching include:
- Citrus fruits and juices – Lemons, limes, grapefruit
- Vinegars – Balsamic, red wine, apple cider
- Tomato-based products – Pasta sauce, ketchup
- Cleaners and disinfectants containing acids – Toilet bowl cleaners, tile cleaners
- Wine and alcohol
- Carbonated beverages like soda and sparkling water
While quartz is marketed as stain-resistant, it is not entirely stain-proof. Spills should be wiped up promptly before the acid can penetrate the surface. However, etching can still occur over time with regular use. Highly acidic substances can begin causing damage on contact.
Signs of Etching Damage on Quartz
There are a few key signs that indicate etching or corrosion on your quartz countertops:
- Visible pits, scratches or dull spots – Etched areas appear discolored and lose their shine.
- Smooth areas turn rough – Acid erosion causes the surface to feel uneven or gritty rather than smooth.
- Water marks or mineral deposits – Etching allows liquids to penetrate and leave behind hard water stains.
- Increased staining – Damaged areas become more prone to absorbing dyes from spills.
The damage often starts off faint and worsens over time with repeated exposure. So it’s important to address early signs of etching before it becomes more severe.
How to Repair Mild Quartz Etching
If the etching on your quartz is mild, there are some simple DIY methods you can try first:
Baking Soda and Water Paste
Baking soda is a mild alkaline that can help neutralize acid damage on quartz. Mix baking soda and water into a spreadable paste. Apply it to the affected area and let it sit for 5-10 minutes. Then scrub the area using a soft cloth, sponge or nonabrasive scrub pad. Rinse well and dry with a microfiber cloth. Repeat as needed until the etched spots disappear.
For very shallow etching, sometimes a little light buffing is all that’s needed. Try gently rubbing the spots using a plastic scouring pad or soft toothbrush. You want to use mild abrasives that won’t scratch the quartz. It may take some trial and error to find the right level of scrubbing.
pH-Neutral Stone Cleaner
Look for a cleaner specifically formulated for engineered stone and quartz. These are designed to remove etching, residues and stains without damaging the surface. Apply a small amount to the etched area, let it sit briefly, then wipe clean. Avoid acidic cleaners which can make etching worse.
Blended White Vinegar
For a stronger DIY etching treatment, mix 1 part white vinegar with 4 parts water. White vinegar is less acidic than other types. Apply the diluted vinegar and let it sit for a minute or two before scrubbing and rinsing off. Be very careful using vinegar as it can warp some quartz surfaces.
Automotive Buffing Compound
Use a plastic-finishing compound or automotive polish intended for clear coats. Rub a small amount over the damaged area using a soft cloth. Take care not to apply too much pressure. This helps smooth away the top layer of the quartz.
How to Repair Severe Quartz Etching
For more stubborn etching that doesn’t respond to simple DIY approaches, stronger solutions are required:
Professional Etching Cream
There are specialty etching repair creams made for quartz and engineered stone. Brands like StoneTech or GranQuartz sell products you can apply yourself at home. Simply rub the cream into the affected area, allow time to penetrate, then wipe away residue. Multiple applications may be needed.
Baking Soda Poultice
A more intensive way to treat etching at home is with a baking soda poultice. Mix baking soda with hydrogen peroxide to form a thick paste. Spread paste over the etched spots, cover with plastic wrap, and allow to sit overnight before rinsing clean. The poultice pulls stains and acids out of the damaged pores.
Wet Polishing and Honing
Professional quartz fabricators have access to specialized tools like wet polishers to resurface and hone away etching. This is especially effective for deep scratches. Expect to pay $100-200 or more for a professional to wet polish your countertops, depending on the size of the job.
For severe etching or damage that extends across a large surface area, a full resurfacing may be required. This involves mechanical grinding and polishing to remove several thin layers of the quartz surface. Resurfacing can restore the countertop to like-new condition, but typically costs $200-400.
Tips to Prevent Quartz Etching
While professional repair is sometimes necessary, prevention is the best medicine when it comes to countertop etching. Here are some handy tips to help avoid damage:
- Wipe up spills immediately, especially acidic liquids like juice or wine.
- Use coasters under glasses and bottles.
- Clean with a pH-balanced quartz cleaner, not vinegar, bleach or harsh chemicals.
- Avoid scraping or scrubbing with abrasive pads. Use soft sponges and cloths.
- Use trivets and hot pads under hot pans and appliances.
- Re-seal quartz every 1-2 years with a penetrating sealer made for engineered stone.
- Don’t cut food directly on the counter. Use a cutting board.
With proper care and maintenance, it’s possible to enjoy beautiful, long-lasting quartz countertops in your kitchen or bath. Pay attention to preventing etching, and address any signs of damage right away. In many cases you can successfully repair shallow scratches and dulled areas yourself. Seek professional help for deep etching that requires more intensive buffing or resurfacing.
Frequently Asked Questions About Repairing Etched Quartz Countertops
