Grout ‘n Groove only.

New, but may have some lint since it’s been out of the box.

As is.

From instruction manual: for aggressive, cleaning of grout lines, corners, and narrow areas also for grooves, such as sliding door tracks. CAUTION hard scrubbing with this brush in one spot for too long could wear or remove grout do not use with self scrubbing cleaners that states “no scrubbing required.”
