Spring must be in the air, with us all cleaning stuff.
We've got a white tile splash back behind the gas hob, which has white grouting. The tiles are easy enough to keep clean, but the grouting is starting to discolour. Any suggestions??
I've tried a toothbrush and Janola but didn't want to leave it there too long, in case it did something to the grouting. It did help a little, but still the grouting isn't white any more.
