Best Penetrating Oil

<usual disclaimer>?

Nothing best than COCA COLA

I'm requesting a MSDS for Coca-Cola be added to our records. This should be fun.

Look at pH...

They only have to have one if it is 'used in process'

"OK, Doorman. This is a pretty nice setup. Now let's have a look at your MSDS book. During our tour, I saw a guy using something labeled 'HomeBrew'. I would like to see that MSDS in particular."

In the world of today, I cannot/would not allow this in my shop.

AAAaaaaannnddd,

Many common household cleaning solutions and solvents become hazardous materials if you take them to work.

I might try this one at home. I have both liquids. I probably wouldn't use it on plastics as a lubricant.

I find dry wax sparingly used during assembly speed disassembly of plastics.

Good idea.

Wax is also very good for woodscrews (into wood, or e.g. plastics wall plugs). I keep a candle stub in my screw box.

_{(that boy at the back - stop sniggering)}

I keep soap in my screw box.

Soap's good too - I use it when I can't find my candle .

What is dry wax?

I googled it and all I got was a hair gel.

Simonize - Google that

My preferred method and when something is stuck time what I have more of. I use oil of wintergreen soak it and leave it for a while. Overnight if you have the time (and patience). It may help to build a little wall of putty (or whatever) around it to allow the penetrant to pool, rather than to run off (the penetrant, not you!). After a good soak try tightening and loosening again. If no joy then is time for EDM

I found that wrapping or tying cotton string or an old shoe lace around a valve stem or stud just above the nut and then squirting the WD-40 or whatever on the string worked pretty good too.

A couple of years ago my neighbor who was an ex-Marine gave me an olive-drab can marked Penetrating Oil that he referred to as "monkey piss". I remember we used the same name to what we used aboard ship many moons ago.

Yep build a little cone of monkey $hit around the nut and fill with monkey piss and the nut comes off after dinner

Do you allow any of the others. Read the MSDS sheets on those. They all have issues if your only looking at written materials, such as MSDS sheets.

Yes, we use Liquid Wrench (not an endorsement). Yes, I have the MSDS for it in the book. And I agree, it is not something to add to your coffee either... the point was (and as lynlynch added to) there are things that are simply not allowed on premises if there is no MSDS on file. We are required to have an MSDS on sawdust, for crying out loud!

When the MSDS sheets began to show up at the work place some years ago. They were brought in because some company's did not care to much about employees. Now it is common to see them in most every work place. In some of the Hazardous Materials training I have done for various company's over the years. I have always demonstrated a MSDS sheet for what they are, information. Take the one that covers water, if you remove the label that tells you it is H2O, you would not have the stuff in the plant by the time you got done reading it (had a plant manager state that once). It all takes some very common sense add into the mix as well.

DHMO and Cortisone...er for loosening stiff joints

This is Really prescient, as next year southern californias new limits on voc's for metalworking fluids (covering this category) come into effect.

Interestingly, Acetone is NOT considered a VOC by their "Scientists" (Even though Dr. Cohen taught us it was back in Organic Chem I).

I spoke with some folks a week or so ago at a leading manufacturer that is trying to figure out how to reformulate and still have a product that works...

We are rapidly approaching the day where the Greens will have outlawed every thing/substance needed to manufacture (or grow) anything of value.

Manufacturers are close to being outlaws just by the sheer volume of legal code prepared against our activities at all levels of govt.

We will be green and poor.

BTW, I used a blended concoction quite similar (ATF and ???? wasn't acetone) for my .45 when I was still competitive shooting. Far better than the commercial products. we called it "snail snot."

milo

ATF for your ACP? Did you dip, or spray?

I was not aware that acetone was given a pass.

Nail polish remover lobby.

They say that acetone is not a contributor to Photochemical smog. I have been in shops that have dip tanks of acetone. One Static spark...

It does a great job on tiny little swiss parts...

I'll go try to find my snail snot formula

When I started working in an engineering plant, there was a Trike (trichloroethylene) tank, which was used for dipping everything from cylinder blocks to Rotring pen nibs.

It did a pretty good job, not as good as acetone, but it didn't get upset if you were smoking while you worked.

This is part of the toxicology entry for Trike, from http://msds.chem.ox.ac.uk/TR/trichloroethylene:

-----------------------------------

Carcinogen. Mutagen. Toxic. Possible teratogen. Human mutagenic data. May cause systemic effects if swallowed or inhaled. May be addictive. Harmful if swallowed, inhaled or absorbed through skin. Narcotic. Severe irritant. May cause dermatitis. Typical STEL 150 ppm. Typical LTEL 100 ppm. Carcinogen category 3.

-----------------------------------

Is it still used?

Wasn't that one of the chemicals that did not burn, but changed its character for the worst if passed though a flame (cigarette?)?

I remember we were warned (60s RN) NOT to smoke anywhere near it for that reason alone.....

Maybe a good chemist here can confirm or deny the action of burning the gas that the liquid gives off....looking at Wiki suggests Phosgene gas can be produced...quite a killer!!

The effects of heating, though not fully described here on Wiki, tend to suggest that its not a good move:-

http://en.wikipedia.org/wiki/Trichloroethylene#Chemical_instability

When inhaled, trichloroethylene produces central nervous system depression resulting in general anesthesia. Its high blood solubility results in a less desirable slower induction of anesthesia. At low concentrations it is relatively non-irritating to the respiratory tract. Higher concentrations result in tachypnea. Many types of cardiac arrhythmias can occur and are exacerbated by epinephrine (adrenaline). It was noted in the 1940s that TCE reacted with carbon dioxide (CO₂) absorbing systems (soda lime) to produce dichloroacetylene and phosgene.^[6] Cranial nerve dysfunction (especially the fifth cranial nerve) was not uncommon when TCE anesthesia was given using CO₂ absorbing systems. These nerve deficits could last for months. Occasionally facial numbness was permanent. Muscle relaxation with TCE anesthesia sufficient for surgery was poor. For these reasons as well as problems with hepatotoxicity, TCE lost popularity in North America and Europe to more potent anesthestics such as halothane by the 1960s.^[7]

Its just a different one more carbon up from carbon tetrachloride And As I recall, Carbon tet fire extinguishers plus fire = phosgene gas...

Those have been outlawed for many many years here.

Correct about Carbon TET. I always cringe when told about someone using Carbon TET as coolant in machining; surprising how often it's heard.

Trouble is, some of the "facts" reported above are wrong. At least one of them was wrong in the original article which I have buried somewhere. This is not "recent." This was not nuts on bolts, rather rods in holes that were pressed out--maybe that's why the numbers are pounds, not foot-pounds. The ATF was actually power steering fluid. It's still interesting data; I've been using Kroil for years. Should I root out my original article?

Natural eucalyptus oil is excellent to soak rusted studs etc.

But did anyone try old style Coca Cola - the strong stuff from the 1950's. You would have to make it yourself now from the concentrated syrup used at soda fountains. (do they still have those??) The old maintenance man at the local dairy told me in 1965 that was all they ever used on rusted bolts. (There is a bit of phosphoric acid in Coca Cola) It did seem to work better than WD40.

A product with a viable MSDS that works well on all metal fittings is CorrsionX. It is an absolute life saver when disassemblig motorcycles for restoration. Interestingly I was using Penzoil Power Steering Fluid Mixed at 60% oil, 40% Acetone before switching to the CorrosionX. The Corrosion is a superior product that I wont be without. While the CorrosionX isn't exactly fire proof, it doesn't ingnite like rocket fuel either. I have never used anything that was as effective.

I didn't realise that smutty jokes were not allowed,.

Actually, the joke was in the mind of the reader.......wow!!! I didn't actually say anything dirty!!!

Toyota has sold a lubricating penetrant liquid in the recent past that has worked wonders on freeing rusted metal components. It was a little pricey, but the results were more than worth the initial cost. And since a very small amount is needed for each application, a single can lasts for a significant number of uses. Check the parts group at your local dealership for availability and price.

thanks for posting this info. i use 2 cycle oil myself, but the best i've ever tried was used compressor oil from a junk refrigerator. new compressor oil won't work. i think there's acid from the winding in used oil that makes the difference.

Another side note, for those who might still not know : Some penetrating oil is NOT to be used as a general lubricant or preservative treatment, at least not where dissimilar metal are in contact - found out that it generated quite a bit of interaction between an aluminum piston and a steel cylinder : piston suffered the most - of course, it should have been obvious but then, no one is perfect...
