The best performing penetrating oil (i.e. freed a rusty nut/bolt with the least torque required) to be a 50/50 mixture of automatic transmission fluid and acetone.

I've been using a 50-50 mix of Kroil and acetone for years for a rust/crud soak and it works- acetone has a dangerous flash point, so well ventilated and spark free areas are of concern- as our friends in the German Gun Collectors might say- "Rauchen Verbotten"!!!
