Rather than hijacking the other penetrating oil thread, I'll just start fresh.

I've always used PB Blaster and it visually doesn't look oily a day or so after application. At that rate, I am not sure if it's actively penetrating anymore.

I've always had decent luck with PB Blaster, but is there anything out there that's better? I also wonder if mixing ATF at a ~25% ratio would help allow the penetrating oil to stay on the parts longer.

Ive been using Kimball Midwest's penetrating oil for 5 or 6 years with no issues, everyone talks about Kroil, but Im not really sure if theres too much of a difference between all of the major name brands out there. I saw a video that heated the [censored] out of a stuck bolt and used candle wax to loosen it by just melting it down the threads!

Kroil, Liquid Wrench and CRC Freeze-Off are the ones I have had the best luck with. On studs like pipe to manifold I use a hand held hydraulic nut splitter if possible but if not heat the nut cherry red then hit the stud with blast it canned air turned upside down then immediately shoot it with penetrant.

Liquid wrench is pretty good.
Rost off from wurth is also good.
Pentrazen from i cant remember who is one i use most at work along with a product called penefree.

At home i have pentrazen, blaster and liquid wrench.

I'll give the liquid wrench a try since I'd like it prior to the weekend..

Had to Google Ed's Red.. It's the ATF and acetone mixture. I'll give that a try too I guess.

I've moved on from PB Blaster to Kroil, WD-40 penetrant, and liquid wrench- but there is a little PB blaster I keep mainly for its can. It is to help remind me not to just spray it on and start spinning. Sometimes you may need to tap with a hammer or jar it (heard online) by actually tightening it slightly.

Is Kroil anything like PB Blaster ? I mean does it sting your skin like PB Blaster does ? That PB Blaster has some kind of acid in it and it burns.

A good option for if you're doing penetrating oil for a few days in advance, Fluid Film penetrates somewhat slowly, but will stay where sprayed almost indefinitely.
