Always been a fan of Kroil, will have to try the home brew.

 

[jforb]

They left out the "torch" which is my go to for really stuck things.

 

[DiverRay]

I've been using the home brew for years! MAP torch if it doesn't want to move with home brew!
Overdrive is a trucker magazine from the USA. I'm collecting a small pension from the Teamsters!

Love my BoltBuster
But I always soak in ATF, then brake fluid. Both recycled, and used heavily.

Kroil and ATFmix have always been my go to buster. Using a micro-butane torch helps.This mix has been the sauce for RR owners due to the use of fine treads on these cars.

I do keep Gibbs and SeaFoam, but they are both expensive

I use "cool tool ll" as a lubricant for machining metal (drilling etc.) Discovered
by accident it also works great as a penetrating oil.

I had a bit of trouble with a stuck nut on my golf a couple of weeks ago when changing a shock.

Really tight, wouldn't break free with penetrating fluid and standing on this breaker bar and extension.

It felt like something was about to let go here in a bad way.

So tried heat, then a chisel to cut it.

Still wouldn't budge, so got out the finger sander out.

Still wouldn't budge, then the penny dropped, it's a captive nut.😵

What an idiot!

Cut off, damage welded up, and repainted.

How to Jailbreak a Captive Nut

A friend of mine had recomendhttps://www.zoro.com/lab-safety-supply-wash-bottle-standard-spout-16-oz-yellow-6fau5/i/G3043957/?utm_source=google&utm_medium=surfaces&utm_campaign=shopping%20feed&utm_content=free%20google%20shopping%20clicks&gclid=EAIaIQobChMIvI-Gg_jn_QIVRsmUCR2ijwBdEAQYBCABEgKwiPD_BwEed the home brew to me many years ago. I never wanted to try it because I only use penetrating oil once every 6 months or so. I always figured the Acetone would be all evaporated by the time I used it a second time. But I see from some of the videos, if you use a plastic container that can handle acetone, you can actually see the parting line between the two liquids and you will know if the acetone evaporated or not. Next problem is the bottle spray mechanism. I have several sprayers that work with acetone or alcohol, for several months, but non for years. So a laboratory squeeze bottle might make the most sense.

I use bottles like these for gun wash and it doesn't seem to evaporate noticeably between use.

 

[NYw126-91]

These are commonly used in spray shops loaded with solvents to flush out spray guns as Race has mentioned. I use them here also

I use PB Blaster. It has never failed me. You need to give it some time to work.

I have used PB Blaster as well and with good results. Plus its cheap you can get it almost anywhere. I have found WD 40 to not be as near as good as PB Blaster. I don't use WD 40 for much of anything anymore.

Homebrew for years as well, good for the junkyard trips, put in one of the bottle for bicycle chain lube . But still have the pb blaster, the kano oil is so corrosive that the bottle started to leak... well I had it for over 20 years...
I found knock'er loose, freeze off at one place when I had to do an exhaust manifold, everything went onto those nuts... even the blue wrench, the impact and the breaker bar... but I finally won after repeat soaking for a few weeks...
thank you for posting the various torque needed.

My dad was a machinist and always had a bottle of red mystery oil around. Always seamed to work when needed.

After 20 years, the can might have rusted through from the outside. My old small can of Kroil, that I refilled from a gallon can, had rust on the outside upper portion of the can, so I used Kroil to dissolve it before it corroded through.
