Ive been collecting bottle caps to do some resin art and have been using either heat or acetone to remove the plastic liners from beer bottle & other bottle caps, based on the suggestions from Resin Obsessions youtube tutorial. It seems like some caps are a lot easier to clean than others!
Yuengling, Angry Orchid, Corona, and Coors all come off without any residue (I like these caps a lot for that reason!).
Then there are some bottles that come off but leave some residue.
Then there are some that wont come off at all no matter what I do.
Just something I noticed. 🙂
