Scott, I think acetone and plastic don't' go hand in hand together. I think it will eventually softens the integrity of the plastic, therefore, you have mess of the spillage. If you can call the 800# on the can and ask the Manf.. if they know of an alternative container for you that would help you, since they know the strength of their chemicals. The other thing I was thinking is to call container store and ask them if they have any special cap for the containers for people with your type of difficulties. or they may have just the caps that you can replace yours with. there is also a gadget like a big teethed V shape that sits in a circular base then you just push your container lid or cap into it and twist it to open. I know that container store has it ,but not sure if Walmart or target would have them. Good luck man. i hope I could help.
