does climbing chalk expire?
Climbing chalk does not have a specific expiration date. It is a simple compound of magnesium carbonate that does not degrade or spoil over time. As long as the chalk remains dry and free from moisture, it should remain effective for its intended purpose. However, over time, chalk may absorb moisture from the air, which can affect its texture and performance. It can become clumpy and less effective at absorbing moisture from your hands. If your chalk becomes clumpy or less effective, it may be time to replace it. Storing your chalk in a sealed container or a chalk bag can help prolong its lifespan and prevent moisture absorption.
