Chalk brush
A small brush climbers use to clean holds.

A chalk brush knocks powder and skin grime off a hold so the next try has friction. It does not fix a hold that has been coated in thick liquid or rosin. Those films need the gym's cleaner, not a boar-hair brush.
Brushing is part of bouldering etiquette. Brush the hold you just used if you left it worse than you found it, and do not stand under someone who is climbing.
TWO STONES Climbing brush
A bouldering brush for chalk and rubber on holds. Brushes remove loose chalk. They do not remove a dried liquid film.
