Penetrating oil comparison

Here is some information that I ran across,
Interesting stuff

Penetrating oil comparison
Machinist’s Workshop magazine actually tested penetrants for break out torque on rusted nuts. Significant results! They are below, as forwarded by an ex-student and professional machinist, Bud Baker. Don’t forget the April 2007 “Machinist’s Workshop” magazine comparison test.

They arranged a subjective test of all the popular penetrants with the control being the torque required to remove the nut from a “scientifically rusted” environment.

Penetrating oil ….. Average load

None …......... ......... 516 pounds
WD-40 …......... ...... 238 pounds
PB Blaster …......... . 214 pounds
Liquid Wrench ….. 127 pounds
Kano Kroil …......... 106 pounds
ATF-Acetone mix….53 pounds


The ATF-Acetone mix was a “home brew” mix of 50 – 50 automatic
transmission fluid and acetone. Note the “home brew” was better than any commercial product in this one
particular test. Our local machinist group mixed up a batch and we all
now use it with equally good results. Note also that “Liquid Wrench” is
about as good as “Kroil” for about 20% of the price. Your experience may vary, etc., etc.

Fascinating...seeing as WD-40 isn't even a lubricant, just a moisture deterrent oil (WD=water displacement, it just removes moisture). Liquid wrench has a few varieties as does other things I'm sure...do you have a link to the original info?

I wish they had tested CRC Knock er loose. Ive witnessed the stuff work first hand. We had a deck spindle on a lawn mower in my shop, needed a new pulley but it was totally rusted to the shaft. We put it in the 20t press and it started to fold the pulley but never moved the shaft. I hit it with knocker loose 2 times and went home...came back the next morning and when I picked it up to put it in the press, the pulley slid some, I wiggled it off by hand, the CRC had gotten all the way down the full 2" depth of the pulley/shaft.

WD40...just plain sucks, Its good for fogging an engine for storage, bout it.

From the WD-40 site...



What does WD-40 do?
WD-40 fulfills five basic functions:
1. CLEANS: WD-40 gets under dirt, grime and grease to clean. It also dissolves adhesives, allowing easy removal of labels, tape and excess bonding material.
2. DISPLACES MOISTURE: Because WD-40 displaces moisture, it quickly dries out electrical systems to eliminate moisture-induced short circuits.
3. PENETRATES: WD-40 loosens rust-to-metal bonds and frees stuck, frozen or rusted metal parts.
4. LUBRICATES: WD-40's lubricating ingredients are widely dispersed and tenaciously held to all moving parts.
5. PROTECTS: WD-40 protects metal surfaces with corrosion-resistant ingredients to shield against moisture and other corrosive elements.

WD-40 is basically solvent and mineral oil.

It's funny/cool to me that you mentioned the ATF.

Because before I read your post through, I was going to reply, that I am such an old fart that I remember just useing ATF to help loosen nuts,bolts etc. .

The acetone and atf does work and has actually been talked about quite a bit here on JF. It's no hoax.

I am forwarding this , but do not know the truth about every one of the applications

Certain many are true !


Before you read to the end, do you know what the main ingredient of WD-40 is?

I had a neighbour who had bought a new van. I got up very early one
Sunday morning and saw that some vandal had spray painted red all around
the sides of this white van. I went over and told him the bad news. He
was very upset and was trying to work out what to do, probably nothing
until Monday morning, since nothing was open.

Another neighbour came out and told him to get some WD-40 and clean it
off. It removed the unwanted paint beautifully and did not harm the paint
that was on the van. I'm impressed!
WD-40 - how did someone work out it would do that?

'Water Displacement No.40' The product began from a search for rust
preventative solvent and degreaser to protect missile parts. WD-40 was
created in 1953 by three technicians at the San Diego Rocket Chemical
Company. Its name comes from the project that was to find a 'water
displacement' compound. They were successful with the fortieth
formulation, thus WD-40. The Convair Company bought it in bulk to protect
their atlas missile parts.

Ken East (one of the original founders) says there is nothing in WD-40
that would hurt you. It's the first thing that has ever cleaned that
spotty shower screen. If yours is plastic, it works just as well as on
glass. It's a miracle! Then try it on your cooker top .... Kazamm! It's
now shinier than it's ever been. You'll be amazed.


Here are some other uses:

1. Protects silver from tarnishing.
2. Removes road tar and grime from cars.
3. Cleans and lubricates guitar 20 strings.
4. Gives floors that 'just-waxed' sheen without making them slippery.
5. Keeps flies off cows.
6. Restores and cleans blackboards.
7. Removes lipstick stains.
8. Loosens stubborn zips.
9. Untangles jewelry chains.
10. Removes stains from stainless steel sinks.
11. Removes dirt and grime from the barbecue grill.
12. Keeps ceramic/terra cotta garden pots from oxidizing.
13. Removes tomato stains from clothing.
14. Keeps glass shower screens free of water spots.
15. Camouflages scratches in ceramic and marble floors.
16. Keeps scissors working smoothly.
17. Lubricates noisy door hinges on vehicles and doors in homes.
18. It removes black scuff marks from the kitchen floor! Use WD-40 for
those nasty tar and scuff marks on flooring. It doesn't seem to harm the
finish and you won't have to scrub nearly as hard to get them off. Just
remember to open some windows if you have a lot of marks.
19. Dead insects will eat away the finish on your car if not removed
quickly! Use WD-40!
20. Gives a children's playground gym slide a 20 shine for a super fast
slide.
21. WD-40 is great for removing crayon from walls. Spray on the mark and
wipe with a clean rag.
22. Also, if you've discovered that your teenage daughter has washed and
dried a tube of lipstick with a load of laundry, saturate the lipstick
spots with WD-40 and rewash. Presto! The lipstick is gone!
23. Lubricates tracks in sticking home windows and makes them easier to

open.
24. Spraying an umbrella stem makes it easier to open and close.
25. Restores and cleans padded leather dashboards in vehicles, as well
as vinyl bumpers.
26. Restores and cleans roof racks on vehicles.
27. Lubricates and stops squeaks in electric fans.
28. Lubricates wheel sprockets on tricycles, wagons, and bicycles for
easy handling.
29. Lubricates fan belts on washers and dryers and keeps them running
smoothly.
30. Keeps rust from forming on saws and saw blades, and other tools.
31. Removes splattered grease on stove.
32. Keeps bathroom mirror from fogging.
33. Lubricates prosthetic limbs.
34. Keeps pigeons off the balcony (they hate the smell).
35. Removes all traces of duct tape.
36. Folks even spray it on their arms, hands, and knees to relieve
arthritis pain.
37. WD-40 attracts fish. Spray a little on live bait or lures and you
will be catching the big one in no time. Also, it's a lot cheaper than
the chemical attractants that are made for just that purpose.
Keep in mind though, using some chemical laced baits or lures for
fishing are not allowed in some counties .
38. Use it for gnat bites. It takes the sting away immediately and stops
the itch.


And for some reason............spray it on your arthritic knee joints etc
and it will ease them.


P. S. The basic ingredient is FISH OIL..

If you start using atf and acetone it's pretty hard on spray bottles. I use old fashioned metal oiling cans.

They only use acetone on the test but it has a high flash point and evaporates out of the can fairly quickly. I've had good luck cutting the ATF with mineral spirits or lacquer thinner instead of acetone. Definitely keep it away from paint.

My favorite on the WD40 list is #15, camoflaging scratches in marble floors. Yeah, an oiled marble floor sounds awesome. I can already feel the crack in my skull.

WD40 is helpful in the shop, it's a convenient lubricant to help keep rusty threads from binding and breaking. Nothing to do with breakaway torque, we're talking the kind of problems that arise when the nut is two turns loose and the threads jam with rust.

Be REALLY careful... Acetone is dangerous. The fumes can do huge damage to your body, as can absorbing it through your skin.

I use Liquid Wrench only.
