Wasn't that a K&W product at one time? Seems to me it was pretty good but I haven't seen it around for a long time.

I use it, it is a decent penetrating solvent. You are going to get many, many options others may say are better. No penetrating fluid is 100% all the time.

I've heard of Knock'er Loose oil, but I thought it was a joke.

Ok, it looks like CRC makes Knock er Loose in 2 formulas. They have it under the CRC brand and then they have a "technician grade" marketed under the K&W name. I've only used the K&W branded product.

I've used it extensively. It works well as a penetrant/ lubricant. Kroil is the best penetrating solvent, but doesn't provide any lubricant when backing out a fastener. It's also about half the price of kroil.

First penetrating oil I was introduced to was K&W Knock'er Loose. 1967 or 68. The can was copper colored and black.

It is still rated the best overall penetrant.

C&C Equipment (YouTube) uses it by the case I think. I have seen Diesel Creek use it also

My uncle told me if you got a nut that won't loosen to tighten it up first.

He was dead serious, the man is in his 80's so I have to believe him.

My father's advice also . Often less corrosion in that direction allowing you to break the initial bond .

When my son started to work at Cat Engine plant they still Re-manufactured engines. He took them apart, they bought Kroil oil by the Barrell and Sprayed all those used Engines down before taking them apart.

I was a professional ASE tech for about 8 years until the financial collapse of 08. I tried many different brands over the years and found Mopar Rust penetrant to be the best, but I’m not paying that kind of money for a marginally better product. I found that most any commercial rust penetrant left to soak for a few minutes, followed by a mapp gas or propane torch was the superior method by a very wide margin. Most dealers at least in the south don’t have oxyacetylene torches. Sorry if that was a sidetrack to the question, but I’ve probably tried at least 20 depending on what was in a parts department or at a parts store.
