How do you remove the compound on the edge?

"Zippo lighter fluid is naptha. Cleans better, won't harm plastic, dries quicker with no oily residue like regular paint thinner."

I use Zippo lighter fluid.  So easy to carry and the can is a virtually leak-proof container with a plastic swivel spigot.  Easy to open/close.  Doesn't take much on a piece of paper towel to remove compound residue.  Evaporites quickly and leaves no residue.

Works for me!
