Do carabiners need to be dry before storage?

Carabiners should indeed be dry before storage. Moisture can lead to corrosion and degradation, especially in metal components. If a carabiner is stored while still wet, it can accumulate rust over time, particularly if it is made from materials susceptible to oxidation, such as steel. Furthermore, any trapped moisture can foster the growth of mold or mildew, especially in the case of carabiners used in conjunction with other climbing gear or harnesses made from fabric.

Storing carabiners in a dry condition helps ensure longevity and reliability for future use. Even carabiners made of corrosion-resistant materials, like aluminum, benefit from being stored dry because excess water can still lead to other forms of damage or malfunction. Proper maintenance, including drying before storage, is crucial for the safe and effective use of carabiners in rope rescue and climbing activities.
