Guide

How to choose

How to Choose a Bouldering Brush

Bristle type is key. Natural boar hair bristles are the standard — they clean holds effectively without damaging the rock surface.

Key Factors

Bristles: Boar hair is the go-to for most climbers. Soft enough not to damage holds but firm enough to scrub off chalk. Nylon bristles are more aggressive and work well on textured holds.

Handle: Ergonomic handles give better leverage for scrubbing. Some brushes have longer handles for reaching high holds from the ground.

Size: A standard-size brush covers most needs. Some climbers carry a small brush for detailed work and a large one for big holds.

Attachment: Look for a clip or loop so you can hang the brush from your chalk bag or harness.

Budget Guide

  • Budget ($5-10): Basic boar hair brush, gets the job done
  • Mid-range ($10-20): Ergonomic design with quality bristles
  • Premium ($20+): Telescoping handle or premium materials
FAQ

Common questions

Chalk buildup on holds reduces friction and makes them slippery. Brushing removes excess chalk and rubber residue, restoring the hold texture. Outdoors, brushing is also good etiquette — it keeps rock clean for the next climber. Indoors, gyms appreciate when climbers brush holds between attempts.
