Grout Stain

Tips from Real-Estate-Agents.com

Problem

If the grout around your tile is stained and dirty, but you don't feel like digging it out to replace it, try applying a stain.

How to Stain

First, clean the grout with tri-sodium phosphate. Apply and scrub with a small, brass grout brush. Rinse the grout after cleaning and allow it to dry overnight. Then apply the stain.
