Best Penetrating Fluid?

[HillStreet]

I will keep trying to separate my SB51 snowblower fan from the gearbox shaft. I think if I stand the blower up on the auger end I can spray the penetrating oil so it drips into the coupling better, then soak it over a period of days.

What is a real good penetrating fluid to use? I have some Liquid Wrench but it's not doing the job so far.

we have good luck with PB Blaster.. sometimes even whisper a little heat on the stuck objects first and sizzle it in

A very effective penetrating oil is a equal mix of acetone and transmission fluid.

+1 on the antifreeze-acetone mix. Works exceedingly well.

Bill and Pilotman: Should it be anti-freeze or transmission fluid? Or would either work with the acetone?

Ah Ha! I can see how Bill was thinking ATF and typed antifreeze.

I'll second this..!! I thought Kroil was pretty decent, this mix is MUCH better..!! I mix mine in a dish washing liquid bottle, so as the Acetone won't evaporate.

PB is good but for the tough stuff I use blue flame ratchet.
