I would colour seal as this is the only way to get the grout white again....you can't get the dwell time needed on walls..gravity won't allow it
Hi Kevin - have had a look on your site and am happy to order the grout cleanerjust wondering if you also have a good grout brush for saleAnd also do you have something that can clean and polish laminate well - (I would only be using a mop on this as cant spare the equipment)Also I need this for next ThursdayLet men know and thanksG
