How to Get the Silicone Off the Quartz Countertop

Getting silicone off quartz countertops can be a challenging task, but with the right techniques and products, it is possible to remove it completely without damaging your countertops. Here is a comprehensive guide on how to get silicone off quartz countertops.

Why Does Silicone Get Stuck on Quartz?

Quartz countertops are made of engineered stone bonded together with resin. This material is non-porous, so silicone and other adhesives do not absorb into the surface. Instead, they cure and harden on top of the quartz.

Silicone is commonly used during installation to fill gaps between countertops and backsplashes or around sinks. Over time, it can yellow, crack, or peel away, leaving behind stubborn silicone residue. The silicone adheres tightly to the smooth quartz surface, making it difficult to remove.

Easy Methods to Remove Silicone Residue

Here are some simple methods you can try first to remove silicone from quartz countertops without damaging the surface:

Use a Plastic Scraper

A plastic scraper can help gently lift off any loose or peeling silicone. Scrape parallel to the countertop surface to avoid scratching. Be patient and take your time with this method.

Apply Heat

Using a hairdryer or heat gun, apply heat to soften the silicone residue and make it easier to scrape off. Set the heat on low and hold the dryer a few inches above the area for 30-60 seconds. Scrape immediately while warm.

Rub with Rubbing Alcohol

Pour some isopropyl rubbing alcohol on a soft cloth and rub the area to dissolve and loosen the silicone. Reapply as needed and wipe clean. Be careful not to spill alcohol on other surfaces.

Dab On Goo Gone

Goo Gone is a commercial adhesive remover designed for jobs like this. Apply it to silicone areas and let it soak for a minute. Wipe off residue with a dry cloth. Rinse the area afterwards.

Using Chemical Silicone Removers

If you have a significant amount of silicone buildup that won’t budge, you may need a stronger chemical remover formulated specifically for silicone. Here are some options:

Silicone Sealant Removers

Look for products like Goo Gone Silicone Sealant Remover, Motsenbocker’s Lift Off, or Dumond Chemicals Peel Away 7 at home improvement stores. Follow instructions carefully.


100% acetone nails polish remover can help dissolve silicone. Use sparingly on a small inconspicuous spot first to test for any damage to the quartz.

Paint Thinner or Mineral Spirits

These solvents may also help break down silicone residue. Take precautions against breathing fumes and protect hands with gloves.

Caution When Using Chemicals

Only use silicone remover products specifically designed for stone and quartz. Check the manufacturer’s instructions. Avoid bleach, ammonia, alkaline, or acidic cleaners. Test on a small area first and do not let chemicals sit too long.

Removing Stubborn Silicone with Scraper Blades

If you have exhausted other options, a single edge razor blade may be necessary for silicone that refuses to budge. Here are some tips for safe scraping:

  • Work slowly and gently to avoid gouging quartz surface.
  • Keep blade flush with countertop as you scrape.
  • Apply heat first to soften silicone.
  • Hold blade at 45 degree angle and scrape off residue.
  • Clean area well when finished scraping.

Preventing Silicone Stains on Quartz

To avoid the chore of removing silicone residue in the future, here are some application tips:

  • Use a high-quality, non-staining 100% silicone designed for stone.
  • Apply painter’s tape along edges to keep silicone only where needed.
  • Use smallest amount of silicone needed and do not over apply.
  • Allow to cure fully before removing any tape.
  • Avoid cleaner with anti-microbial additives that can discolor silicone.

With some effort, patience, and the right tools, you can successfully remove pesky silicone from quartz. Follow these methods carefully to get your countertops looking fresh and residue-free again.

Frequently Asked Questions

Can I use a razor blade to scrape off silicone?

Yes, you can carefully use a single edge razor blade to scrape off stubborn silicone residue. Go slowly and keep the blade flush with the surface to avoid scratching the quartz.

What household products can remove silicone?

Rubbing alcohol, Goo Gone, acetone nail polish remover, and mineral spirits are common household products that can dissolve silicone when applied correctly on quartz surfaces.

How do I soften hardened silicone on my countertop?

Heating the silicone with a hairdryer or heat gun for 30-60 seconds will soften it so it can be more easily scraped off. Be careful not to overheat the area.

Can vinegar or baking soda remove silicone?

No, vinegar and baking soda are not effective at removing cured silicone. Harsher chemical removers designed specifically for silicone work better.

How can I prevent silicone stains on my quartz countertop?

Use high-quality silicone designed for stone, apply sparingly, allow to fully cure before removing tape, and avoid cleaners with anti-microbial additives which can discolor silicone over time.


Removing silicone sealant from quartz countertops takes a little work, but it can be done without damaging the surface. Start with plastic scrapers, heat, and mild solvents like alcohol or Goo Gone. For stubborn residue, use a specialty silicone remover or acetone applied carefully. Prevent future stains by following application best practices when using silicone on quartz surfaces. With some perseverance your countertops will be restored to their former glory.
