Rainbow Chalk Grout Pen

Draw along grimy grout — looks brand new.

What was tested

Gross grout lines making your tile look old? The Grout Pen is a paint marker for tile grout — draw along the grimy line and it lays down fresh cream color that dries fast. No bleach, no scrubbing on your knees, no regrouting. Water-based, low odor, one marker covers a ton of tile. Honest caveat: it's paint, not new grout — match the shade to your tile and skip shower floors that stay soaking wet. CartWorthy verdict: worth it.
