Frequently Asked Questions
Why does my bathroom grout turn dark so quickly after mopping?
Grout sits slightly lower than the glazed tile surface and acts like a squeegee channel. If you mop with dirty water or leave excess soap on the floor, the liquid pools in the porous mortar lines and dries dark.
