I've used it for years, and years. Very happy with it. NO rust, worked on everything, except perhaps heavy copper fouling.

At some point (I had a large supply), I bought some new bottles, and low, and behold, no Teflon.

Like many here, I usually put the liquid in several little military oiler bottles. These are the translucent kind, so you could see the Teflon settling into the bottom 10%-15% or so. Of course, you had to shake the snot out of the bottles, to disperse the Teflon.

Not there anymore.

The new watery BF seems less slick, and slippery to the touch, and just doesn't have the viscosity of the old stuff.

I E-mailed Break Free concerning this issue, and received a "canned" type of reply, as to BF meeting mil-spec, etc., with no confirmation, or denial of the Teflon disappearance.

Does anyone know what, or why this happened ?

I have modified my cleaning regimen, to clean with the new BF, and use the lube/preservative after. The Lube/preservative, seems to still have the Teflon.

Don't have a clue, if the "new" Break Free, still lubes as well, as the old.

I hate change................

I never use breakfree, so I am no expert on it. I know teflon is getting a bad reputation these days from it's use in skillets because the body retains it and people are having it in their blood in levels that alarm doctors. I know there's a lot of push to get it out of cookware. Also, some of the more notorious aftermarket oil additives like Slick 50 use it and they have been thoroughly discredited (and have been forced to pay millions in fines for their bogus claims of reduced engine wear). maybe teflon's time has passed.

A lot of mis-information listed here. "TEFLON" is inert in the body. The publicity about blood levels is about C8, a surfactant that was used in the production of "TEFLON" but is not present in the finished product. C8 was also present in 3M Scotchguard.

Cookware is only a problem if the coating is degraded from excessive heat (above 600 degrees F). You can get get fume fever, but this is a short term health affect.

I worked at the plant where "TEFLON" is made for over 25 years, and am still part of the C8 health study.

I know that benchrest shooters no longer use anything with Teflon, but don't know why.

BR shooters have gotten away from teflon, because 1: supposedly the fumes from it are deadly poison and the heat from the burning powder causes teflon fumes. 2: Supposedly teflon in the bore does not enhance accuracy.

Has anyone had any experience with sperm oil from whales, as a gun lubricant? Supposedly it is a superior lubricant.

It is unsurpassed as a lubricant. But it is all but unavailable today.

There were some transfer cases (New Process, I think) that were designed to use whale oil. They never gave problems.

Sale of wale oil based lubes was stopped in the mid 70s, and shortly thereafter, these same "bulletproof" gearboxes started to have shortened service lives.

CLP Breakfree still has Teflon in it, just not in the tiny bead form it used to be.
The older type with microscopic beads of Teflon had to be well shaken to mix the beads and the solvent, which many people didn't do, causing problems.

Read the label. It specifically says it contains PTFE: Teflon

Sperm Whale oil was a superior lubricant "back in the day" but modern synthetic lubricants have surpassed it in all respects.

I have yet to see convincing data teflon is good for much of anything beyond fry pans. The so called super lubricants containing PTFE that made various claims have yet to prove any of them. Slick 50 in particular has lost every legal challenge and has been forced to pay fines and stop making claims of reduced wear. I am yet to be convinced.

Really? If it is "not present in the finished product" (ie, the products we consumers bought) how did it end up in everybody's blood?

It must have been present in SOMETHING we got ahold of....

I guess it's like the stinking MTBE they forced gasoline makers to put in all the gas sold in kali for so many years that somehow ended up fouling our ground water tables. How it got there is by magic....

Never put any lube with Teflon in it in the bore of your precission rifle. Causes the bullets to fly erratically and open up your groups. Didn't seem to bother pistols, but was a no no in rifles.

Jungle Work

Sort of off topic, but the old line about all we ever got out of the space program was Teflon coated frying pans isn't true.
Teflon has many uses from medical to engineering and others you'd never guess.

And in fact, Teflon didn't come out of the space program, it's a lot older than that.
Teflon was invented in 1938 and was first used for the Manhattan Project.
In order to do gaseous diffusion of uranium hexafluoride, they needed pumps that could operate at super sonic speeds for years in sealed systems without maintenance.
Since uranium hexafluoride is incredibly corrosive, no normal seal or any lubricating grease could be used.

The idea of the Teflon beads is that they acted as microscopic ball bearings between moving metal surfaces.
Super Lube synthetic oils and greases still contain bead type Teflon and they're an excellent lubricant.

According to the hyper-sensitive EPA, there's no evidence that Teflon is harmful to humans.

The EPA is a political contrivance. They can be bought. As for whether PFOA is dangerous, doesn't look good:

Teflon shown to cause harm to the immune system, liver, and thyroid (research)

Researchers from West Virginia University are leading a study observing the effects of perfluorooctanoic acid (PFOA), a chemical used to make Teflon. They have found that PFOA, also used in food wrappers and dozens of other products, may harm the immune system, the liver and the thyroid gland and cause higher cholesterol in children.” The findings of this study could be the first step toward federal safety standards on perfluorinated chemicals, or PFCs, in consumer products.

UCLA study: U.S. Women at Greater Risk from Teflon Chemical


January 15, 2009



WASHINGTON – A major new study published yesterday in Human Reproduction, a European reproductive medicine journal, has found that pregnant women and women of child-bearing age in the United States are at greater risk than previously thought for infertility and reproductive problems as result of exposure to the toxic Teflon chemical PFOA (perfluorooctanoic acid).

They don't like to give it up easily.
