I'm having difficulty cleaning the grout residue from the face of the tiles (which have a matt surface). Is this possibly because I've left the grout to dry for too long before cleaning? Have tried an acid based cleaner but this has taken the colour out of the grout so it's now much paler. Still got patches of grout on tiles. Can anybody suggest a good cleaner that wont damage grout further?
Hope you can help as the tiles dont look entirely clean. Thanks
