I fitted a protective facing sheet to my new bat at the start of the season. When I applied it I found the adhesive to be quite sticky (as adhesive should be) and messy but, when I lifted the sheet off the bat to reposition it, most of the glue stayed on the bat. I'm guessing that this is going be a nightmare at the end of the season when I come to clean it up and prepare it for next season. How do I get this nasty stick glue off the face of my bat, without causing any damage to the willow?
