Can candle wax loosen rusty nuts?

Project Farm wanted to test if candle wax could be used as a penetrating lubricant to loosen rusty nuts, so he put together a pretty comprehensive set of experiments. His findings – candle wax applied to a hot nut doesn’t do a thing to help loosen it. The wax doesn’t  penetrate the fitting.

His recommendation –  Seafoam Deep Creep, actually does do the job.
