How to Get Grout Off Quartz Countertop

Quartz countertops are durable and beautiful, but over time grout can stain and discolor the surface. Removing grout from quartz requires patience and the right techniques to avoid damaging the countertop. Here is a step-by-step guide on how to safely get grout off quartz countertops.

What You’ll Need

  • pH neutral cleaner or stone soap
  • Non-abrasive scrubbing pad or soft cloth
  • Plastic scraper or putty knife
  • Mineral spirits or acetone
  • Microfiber cloths
  • Painter’s tape
  • Eye protection
  • Respirator mask

Cleaning Grout Haze off Quartz

Step 1: Let the Grout Haze Cure

Before removing grout from quartz, allow enough time for the grout haze to completely cure and harden. This usually takes 24-48 hours. Attempting to clean grout too soon could smear it deeper into the stone.

Step 2: Try pH Neutral Cleaner

Mix a pH neutral cleaner or stone soap with warm water according to the dilution ratio on the label. Use a soft cloth or non-abrasive scrub pad to gently scrub the grout haze on the quartz. Avoid using an abrasive sponge as this can scratch the surface.

Rinse thoroughly and inspect if the cleaner removed the grout haze. If not, move on to next steps using mineral spirits.

Step 3: Apply Mineral Spirits

Mineral spirits work well to break down hardened grout residue on quartz. Dip a soft cloth into the mineral spirits and wring out excess. Test first on an inconspicuous area to check for any reaction with the quartz sealant.

Gently rub the damp cloth over the grout haze using small circular motions. Take care not to scrub too hard. Re-dip and rinse the cloth as needed.

Step 4: Use a Plastic Scraper

For stubborn grout that remains after mineral spirits, use a plastic scraper or putty knife. Carefully scrape at the haze working at a low angle to avoid scratching the quartz. Take precautions by taping around the area first.

Apply more mineral spirits to lubricate and break up the grout as you gently scrape. Rinse with clean water and dry completely.

Step 5: Try Acetone (If Needed)

If mineral spirits and scraping fails to remove all the grout from the quartz, try using acetone. Dip a cloth into the acetone and wring out excess. Test first before applying to the entire area.

Carefully rub the acetone soaked cloth over the remaining grout haze. Take all necessary safety precautions when using acetone. Make sure to rinse thoroughly with clean water after cleaning.

Helpful Tips for Grout Removal

  • Allow sufficient time for grout to fully cure before attempting to remove it
  • Use eye protection, gloves, and a respirator mask when using chemical cleaners
  • Test cleaners first on an inconspicuous spot to check for any reaction with the quartz
  • Avoid abrasive pads, brushes, or sponges that could scratch quartz
  • Use light pressure and small circular motions when scrubbing
  • Rinse completely after each cleaning step
  • Dry quartz thoroughly to prevent water spots

Common Questions about Grout Removal on Quartz

How can I prevent grout from staining quartz?

  • Taping around the edges before grouting can act as a barrier
  • Applying a grout release agent or sealer prevents grout from bonding
  • Using an epoxy-based grout instead of cement grout minimizes staining
  • Cleaning and wiping up spills promptly prevents grout from setting

What cleaning solutions are safe for quartz?

  • pH neutral stone cleaners and soap are safe for routine cleaning
  • Hydrogen peroxide helps whiten quartz and remove stains
  • Acetone can be used for stubborn stains with caution
  • Avoid alkaline cleaners which can etch and damage quartz

Can I use a grout haze remover product on quartz?

Yes, look for grout haze removers that are specially formulated for natural stone. They contain acids that help break down mineral deposits. Follow product instructions carefully and test in a small area first. Avoid acidic cleaners that could etch or discolor the quartz.

What should I avoid when cleaning grout off quartz?

Avoid abrasive pads, steel wool, or anything that could scratch the surface. Don’t use harsh chemicals like bleach or alkaline cleaners which can damage quartz. Avoid applying too much pressure when scrubbing grout. This can push the grout deeper into the stone.


Removing grout haze and stains from quartz countertops requires a gentle approach. Allowing the grout time to cure, using non-abrasive tools, and mild chemical cleaners prevents damaging the quartz. Test products first and always take safety measures against chemical fumes. With some patience, the right techniques, and by following these steps, you can successfully clean grout off quartz countertops.
