It's probably too late but I have had good results from heating the glue with a hair dryer when peeling the pad off. It takes the glue right off with the pad.
Any residue can be cleaned off with acetone or shellite.
Hair dryer sounds like a good idea but I found that acetone made no impact at all. Thanks for your input.
Just carefully warming up the board now with an IR light before fitting new grip
