My Dube devil sticks are still in good condition, the tape on the out side was just beat up. I ordered replacement tape for it, and I'm trying to get the adhesive from the old tape off, I'm not have much luck, I tried rubbing the glue off, I got most of it. how ever I still have some left, and I got a very bad blister from doing so. if you have any non painful ideas, let me know.

Try nail polish remover. It's great at taking glue off.

You can also use Grease and Wax remover. You may find this at an Automotive Supply store in the paint section or at a good Paint Store maybe even Home Depot. Nail Polish remover may be way too corrosive as it has an Acetone base. What are the Sticks made of? Goo-Off is a good remover as well ( I think that is what ya call it).
Chance

You might try wd-40. i would try it on a small section first though.....

Chance, the sticks are made out maple wood
I've dropped many times, and almost not a dent in the wood

did I mention I;ve sticked every day for the last two years, and dropped every day, now that's pretty impressive
