Learn how to easily remove excess dried grout using a stiff brush and warm water. This simple technique leaves your tile lines looking neat and professional.

To clean up sloppy grout using a brush, you must first let the excess mortar set until it is firm to the touch, and then use a stiff-bristled brush to scrub away the unwanted residue across the tile surface. Fixing messy grout work is a common part of any tiling project. When applying grout, it is easy to leave behind a hazy film or clumps that spill over the edges of the tiles. If left unattended, this excess material hardens permanently, ruining the clean lines of your hard work.

Rinsing and Revealing the Surface
