So we popped to town to Iechyd Da to pick up the veg first thing then we went to a cheapskate shop, Home Bargains, to try and pick up some recolourer for the grout as we had bought a bottle of "Clean it" last night which, while cleaning it hadn't made it look good as new. SO we couldn't find and recolourer so instead we went around the corner and bought some white Tipex which seems to have worked so far. It will dry etc while we are at gym
