Basic maintenance: Grip can wear out with use, and is affected by oils from our skin. To prolong the life of your grip, clean it *after* heavy use and *before* long periods of storage. This will also make sure it’s grippy, not slippy, when you are ready to flow.
To clean: Use some rubbing alcohol and a cloth, OR a cloth with warm soapy water to remove any oils from the grip. Be sure to wipe away any soap residue with clean water.
