Hi John ... I don't have a compressor, or access to one, so I use a tool to remove my grips - I'll try & find a link to a description or video of how you use it, rather than try to explain, but I've been doing this for several years & it must have saved me a fortune!

Golf Grip Removal Tool
PS - If you go down the tool route search "V - Groove Golf grip remover " on the bay & "clubworks-dg" have it at best price
