Maintain a Clean Bathroom Grout
Grout in the bathroom is one of those areas that can be really difficult to clean. Mildew thrives in the damp atmosphere of a bathroom, and it seems to enjoy hanging around in your grout. However, nothing ever quite gets the grout as clean as you’d like. Until now, that is.

Get a sponge and some WD-40 and go to town on your bathroom tile. It will work wonders on the grout, making it look brand new. After that, use ordinary soap and water to remove any WD-40 residue.
