stain

A stain is a discoloration that can be clearly distinguished from the surface, material, or medium it is found upon. They are caused by the chemical or physical interaction of two dissimilar materials. Accidental staining may make materials appear used, degraded or permanently unclean. Intentional staining is used in biochemical research and for artistic effect, such as wood staining, rust staining and stained glass.

    Little help with tile stain identification pretty please

    I did try to research this - efflorescence? seems to be related to me having tried to clean the grout a bit so maybe just cement residue ? Disappears when wet, CLR did nothing. The tiling was done by the previous home owner who did a pretty rubbish job :(
