CRC Lube petroleum

The risk is that the outer layer softens. Then the effect wears out and you add more -> Repeat until your pieces are frail and fall apart.

And personally I wouldn't use CRC to break it in either, I prefer a manual way even though it's slower. When breaking in by hand you make sure that the cube molds into a form that clones your solving style. CRC just melts the plastic evenly, which doesnt end up in a cube that is broken in but a cube that has thinner plastic layers.
