How to Get Tile Grout Off Quartz Countertop

Quartz countertops are popular in many homes due to their durability, aesthetics, and low maintenance. However, like any surface, quartz can get dirty over time. Tile grout in particular can be challenging to clean off quartz. With the right techniques and supplies, you can safely and effectively remove grout from quartz.

What You Need to Remove Grout from Quartz

  • White vinegar or citrus-based cleaner
  • Soft cloths
  • Magic eraser sponge
  • Razor scraper (optional)
  • Grout haze remover (optional)

Be sure to avoid harsh chemicals like bleach or alkaline cleaners which can damage the quartz surface. Test any cleaning products on a small, inconspicuous area first.

Cleaning Steps to Remove Grout from Quartz

Step 1: Wipe Away Excess Grout

Use a soft, damp cloth to gently wipe away any excess grout sitting on top of the quartz. Try to remove as much as possible right away before it has a chance to dry and harden.

Step 2: Apply Vinegar and Scrub

Pour some white vinegar directly onto the grout residue. Let it sit for 2-3 minutes to soften the grout. Then use a soft cloth or magic eraser sponge to gently scrub and lift the grout haze away. Reapply more vinegar as needed.

Step 3: Use a Razor Scraper for Stubborn Areas

For any remaining grout that won’t budge, use a new, sharp razor scraper held at a 45 degree angle to carefully scrape it off. Apply firm but light pressure, working in small sections. Be cautious not to scratch or gouge the quartz surface.

Step 4: Use a Grout Haze Remover (Optional)

If vinegar alone doesn’t remove all the grout, apply a specially formulated grout haze remover to the quartz. Check the product instructions and let it sit for the recommended time before scrubbing and rinsing clean.

Step 5: Rinse & Dry Completely

Once the grout is removed, rinse the entire surface well with clean water. Make sure to remove any vinegar or cleaning product residues. Allow the quartz to air dry fully.

Tips for Preventing Grout Stains on Quartz

  • Seal quartz countertops before installing tiles to make grout cleanup easier.
  • Wipe up grout immediately during application before it dries.
  • Add a grout release agent like oil, wax, or plastic sheeting to protect quartz surfaces.
  • Apply painter’s tape around the edges of the quartz before tiling.
  • Clean grout spills right away and don’t let grout dry on quartz.

With some mild cleaners, gentle scrubbing, and immediate stain removal, you can keep your quartz countertops looking their best and avoid tedious grout removal. Always test products in an inconspicuous spot first to ensure they are quartz-safe. Handle spills promptly to prevent permanent stains.

Frequently Asked Questions About Removing Grout from Quartz

How long does grout need to sit on quartz before staining it?

Grout can begin staining and etching into quartz in as little as 15-20 minutes if allowed to completely dry and harden. The quicker you can wipe away excess grout, the less likely it will permanently adhere to the surface.

What household items can remove dried grout from quartz?

White vinegar, lemon juice, baking soda, hydrogen peroxide, and magic eraser sponges are common household items that can all help lift and dissolve dried grout from quartz. Avoid harsh cleaners like bleach.

Can I use an epoxy grout that won’t stain quartz?

Yes, epoxy grouts are a good option for tiling quartz countertops because they are less porous than traditional cement grouts. Epoxy resists staining and is easier to remove from quartz before drying.

Should I reseal my quartz countertop after removing grout?

It’s not necessary to reseal quartz after grout removal as quartz itself does not need sealing. However, if you used harsh chemicals or scrape marks are present, you could apply a quartz polish to help blend the surface for a uniform appearance.

What tools can damage quartz when trying to get grout off?

Avoid using metal scouring pads, scrape tools, or abrasive cleaners on quartz as they can scratch the surface. Even soft sponges can mar the quartz’s polish. Use only non-abrasive tools recommended for quartz.


Removing dried grout from quartz countertops takes a bit of finesse, but is very doable with the right techniques. The key is addressing spills immediately before grout has a chance to cure and bond. With some mild cleaners, gentle scrubbing, and patience, you can successfully rid your quartz of pesky grout stains and restore its flawless finish. Handle your quartz carefully and keep sealing and cleaning supplies on hand for when accidents happen.
