Using this climbing brush is a breeze. Simply hold the brush by its poplar wood handle and gently sweep it across the climbing holds to remove chalk. It works great whether you're using the small (S) or large (L) size. When it comes to maintenance, it's important to keep the brush dry. After each use, shake it gently to get rid of any loose chalk. Avoid soaking it in water as this could damage the boar bristles and the poplar wood handle. Store it in a cool, dry place. If you notice any loose bristles, don't worry. Just pull them out carefully to keep the brush in good shape. With proper use and care, this brush will serve you well during your climbing adventures.
