Put that base (or all your overtweaked bases) in an icecube tray, fill it halfway with water, put one drop of vanilla extract in each cube and freeze for 3 days. Pop a few cubes in a glass of Crown or Hennessy (any dark liquor will do) and enjoy the drink while they melt. Rinse off and let them dry prongside down on a clean cotton towel. After that, the overtweaked prongs should not only smell good and taste good, they should be able to hold their weight again. Don't ask, don't tell.
