Grout haze is a semi-white film left on the surface of the tile after grouting. Even if you have diligently wiped down the surface with a wet sponge, the haze will remain and will not come off until you take special measures. Ordinary cleaning methods will not remove it. Removing grout haze is made much easier and more effective with the right grout haze remover.

What Causes Grout Haze

Grout is made of minerals and cement mixed with water. When the water dries, minerals remain on the tile surface. Residual grout haze is a normal part of tiling.

Because grouting involves pulling grout across the tile with a rubber float, the tile is entirely covered with grout at some point. The float scrapes off a majority of the grout, but a thin film remains.

What Grout Haze Remover Is

Grout haze remover is a specialty commercial cleaner that helps to get rid of grout haze—especially in substantial or difficult cases. Grout haze remover comes in different formulas for cement-based grouts and those that aren't cement-based.

Purchasing Grout Haze Remover

Grout haze remover is widely available at any tile store, home improvement store, hardware store, or online. Prominent brands include:

  • DuPont Heavy Duty Grout Haze Remover Quart: Highly rated, reasonably priced professional strength grout haze remover that makes 9 quarts.
  • Stone Care International (SCI) 1 Gallon Tile & Grout Haze Cleaner: Highly acidic pH strips tile of grout haze, as well as soap scum and calcium buildup.
  • Aqua Mix Cement Grout Haze Remover: Organic acid formula that contains no phosphates. In many communities, phosphates have been banned in products such as soaps and TSP.


Be careful not to confuse grout sealer or grout cleaner with grout haze remover.

Tools and materials to clean grout haze

  1. Wait for the Grout to Cure

    Wait a couple of days for newly installed grout to cure before using grout haze remover. But don't wait too long: It is best to remove the haze sooner rather than later because the haze becomes more difficult to remove with time.

  2. Clean the Surface

    Sweep or vacuum the floor thoroughly, then wet-mop the tile to dampen it.

  3. Mix the Grout Haze Remover

    Put on nitrile (chemical-resistant) or latex gloves. Mix the haze remover with water in a clean bucket, following the manufacturer's directions. Normal dilution is used for light haze; a stronger solution or full-strength (undiluted) product may be recommended for heavy residue. Fill a second bucket with clean water for rinsing.

  4. Scrub the Tiles

    Dip a white, nylon-bristle brush into the remover solution and scrub the tile faces. Work in small areas at a time.

  5. Rinse and Repeat

    Rinse the tile faces and grout joints with a sponge and clear water immediately after scrubbing each section. Clean the sponge frequently as you work, and replace the rinse water as it gets dirty. Repeat the same process to scrub and rinse each small section of the surface until the entire tile installation is clean. Let the surface dry.

Tips to Minimize Grout Haze

If you're in the planning stage of installing new tile or if you're thinking about regrouting existing tile, keep a few things in mind to minimize the grout haze problem after installation:

  • Wait until the grout has hardened before you begin trying to remove the haze. If the grout is wet, you risk gouging it out.
  • When grouting, physically drag off as much grout as possible with your gum rubber float. The more grout that remains, the more of a haze problem you will have. The rubber float is your best friend because it is soft enough to drag the grout off but hard enough that its edge will not dig into your grouted joints. Use the edge of the rubber float to pull it toward you and off the tile.
  • Wipe down the tiles with a damp sponge and only water. Use a tiling sponge for this step, not a household cleaning sponge. Tiling sponges are dense and about the size of a big paperback book. Lightly dampen the sponge and wipe off the remaining grout. Be careful not to dig into the seams.
  • Note that initially it may seem like the wet sponge will take off the grout haze, but that is only because the surface of the tile is wet. As the tile dries, the haze will reappear. This means it is time for haze remover.
