After your tiles have been grouted, there's likely to be a bit of residue cement or cement-based grout, silicone leaching, and dirt on them. These will come off easily with a good thorough clean following our steps to remove grout haze and cleaning tiles.
Grout haze is simply an almost invisible residue of grout and latex that has been left to dry on the surface of the tiles after grouting. This will make a tile look dull, easily marked and difficult to keep clean. It’s part of having your tiles grouted and an easy clean solves the issue.
Grout haze is often not picked up during installation as the damp floor will hide any deposits. The effects, however, are noticeable, dulling the tiles and causing them to get dirty very quickly - sometimes even showing footprints. Conventional cleaning methods don’t remedy the problem and the grout haze will remain. This may be in certain patches or across the entire tiled area.
The ease of removal depends on the type of grout used, the texture of the tile surface and when the tiles were laid. The longer grout haze is left, the harder it is to remove as the grout bonds into any open pores on the tile surface. Cement grout and latex modified cement grouts can usually be removed with a Grout Haze Removal cleaner. Epoxy grout is very difficult to remove.
The aim is to remove all traces of the grout haze film on the surface without damaging the stone or tile, or damaging and discolouring the grout itself. It is best to complete a general clean as soon as you have finished tiling to remove any excess grout. Check out our cleaning and maintenance page for more information. If you notice a haze of grout left on the tiles after installation, either buff it off with a dry soft towel or undertake one final clean. Grout haze is generally easy to remove within 48 hours of grouting.
