Grout haze is the cloudy, dull film left on tiles when grout residue isn’t fully cleaned off after fitting. It’s one of the most common problems we see on newly tiled ceramic and porcelain floors – and once it’s hardened, a mop won’t touch it.
What causes grout haze?
When tiles are grouted, a thin layer of grout is left across the tile surface. If it isn’t cleaned off properly before it cures, it dries into a hard, chalky film. On textured or matt porcelain it settles into the surface and can be especially stubborn – leaving brand-new floors looking dull, patchy or permanently dirty.
How we remove it
Identify the grout and tile
Cement-based and epoxy grouts need different treatments, and some tiles are more sensitive than others – so we check before we start.
Test a small area
We test the treatment on an inconspicuous spot to make sure it lifts the haze without affecting the tile or the grout lines.
Apply a specialist haze remover
A remover matched to the grout type breaks down the residue on the tile surface.
Machine scrub and extract
The loosened residue is scrubbed off and extracted, then the floor is rinsed and dried.
The result
With the haze gone, the tiles show their true colour and finish – exactly how they were meant to look when they were fitted.
