How to remove grout haze from porcelain and ceramic tiles

After the new installation of wall and floor tiles it’s not uncommon for a residue of hard grout haze to be left on the tiled surface. This grout residue doesn’t only look unsightly, but it can also harbour dirt, making general cleaning more difficult until successfully removed.

Grout haze can appear in the form of white powder, glossy patches or dull smears or streaks and can be hard to remove if not using the correct method.

Things to remember

When using any cleaning techniques and products, always carry out a small test patch to understand better the required dilution rate and dwell time to achieve desired results.

Apply any solutions or products with a paint brush or sponge onto the affected areas of the ceramic or porcelain tiles, allowing the solution to dwell for a 5 to 10 minutes.

After 5 to 10 minutes, you may be able to start agitating the surface with a stiff brush. Avoid using items such as coloured sponges, as the colour may transfer onto the tiles.

Whilst agitating with your brush, simultaneously rinse the tiles off with plenty of clean water. This will rinse away the grout haze. Once complete, also rinse again to ensure that the grout haze cleaner has been fully removed.

Grout haze should be removed from porcelain tile as soon as possible. The longer the grout haze is left on porcelain and ceramic, the more difficult it is to remove.

The removal of grout haze depends on a few other factors and these include; the type of grout used, how that grout was mixed, how long the grout has had to set and the material of the tile.

Removing grout haze from smooth surfaces made from porcelain and ceramic tiles is far easier than removing it from rougher surfaces like stone.
