Came across this article on different penetrating oils. With all the headaches that we go through removing rusted nuts and bolts, this article sounds promising. I haven't had a chance to try it yet - would be interested to hear some feedback from others.


Machinist's Workshop Mag (tm)recently published some information on various penetrating oils that I found very interesting. Some of you might appreciate this. the magazine reports they tested penetrants for break out torque on rusted nuts.
They are below, as forwarded by an ex-student and professional machinist.

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 almost as good as "Kroil" for
about 20% of the price.

Liquid Wrench, PB Blaster, and WD-40 are all common as hell, and in all my years I've not seen a nickel's worth of difference in any of them.

Thanks for confirming my hunch about Liquid Wrench.

I have tried just about everything on the list except the home brew and I have usually found that Liquid Wrench worked the best and the fastest for me. I have been using it for about 35 years now and it is my first choice everytime for rust frozen fasteners.

The thing I like about Kroil isn't the breaking power, but the ability to "creep" along surfaces. It gets everywhere.

It is expensive, though.

I've been making & using the ATF-Acetone mixture for years now. Works great!

one my fav's is brake fluid
but, I will certainly make myself a batch of the acetone/ATF

isnt acetone the main ingredient in most of the penetrating lubes? it sure smells that way.

Im definatly gonna whip up a batch of the home brew and try it

Acetone may soften/remove some types of paint... just a thought.

yes, as does the brake fluid which I often use.
perhaps that is why the common spray stuff is not nearly as strong - they cant - because or else they'd ruin paint jobs.....

yes - be careful with the "home brews"

What is the % mixing ATF and Acetone ? One part of ATF and how many parts of acetone ?

quote Originally posted by Robert 2: What is the % mixing ATF and Acetone ? One part of ATF and how many parts of acetone ?

50-50 according to the original post.

Yes, its a 50-50 mix. I have mine in a little squeeze bottle. You'll find that the two liquids separate & need to be shaken to mix before use.

Shaken, not stirred.

how many olives?

Personally, I've tasted much worse! I think the ATF helps smooth out the harsh flavor of the Acetone.

Back when I worked in the machine shop one of the guys stored MEK in a Gatorade bottle. It had a slight blue tint to it to help distinguish it from water. Well, he had some Gatorade one day and grabbed the wrong bottle. When asked how the MEK tasted his reply was "It tasted CLEAN".

I like using Deep Creep. It's made by SeaFoam and seems to work really well. It is expensive, though, at about $7 a can.

MEK - are you talking about the paint additive "Methyl Ethyl Keytone" (I believe thats how its spelled)
It is an additive that you can add to paint to help the paint dry or cure faster. According to the MSDS sheet, that stuff is pretty harsh! Can cause possible nervous system damage JUST from the vapors!

Assuming that your story is true, and the MEK is the same that you are talking about.... Did the guy survive?

Is it wierd to like the way PB Blaster smells?

also...

I wish they made a cologne called 'gun oil'...

Acetone can be found at hard ware stores,, ace, homedepot,lowes ect. this is low quality but the good stuff is expensive

I save small squirt bottles like amour all comes in,, you mix your jism of choice in a separate bottle,,just in case it will clogg it up.. I make up a mixture of pb blaster,liquid wrench and synthetic oil and use an eyedropper or just a long thin screw driver,or squirt devise, sometimes I just drip it into a length of vacuum hose..that snakes down to the rusted area

TIP = hard to reach parts can often be reached by dripping your favorite lube onto a thin wire,or coat hanger,ect.. ,,you can watch it run down the wire & reach your objective !! Saw it done in the big time scooter shop
I use to smell often of gun oil,hoppes or outers, not a big turn on for the ladies,,did better just not bathing!! but I do love the smell of gun oil in the morning,, especially if vast amounts of full metal jacket projectiles have stirred it up..every 5th round a tracer.oooooh got me excited again

Ya may trip out about what Im going to say. But I found iodine to work very good. If not the best of anything.
Just use it before ya try penetrating oils.

Deep Creep is good stuff. Some parts stores keeps it behide the counter.
When ya ask for it. Find ya a new guy working there. And Tell him to
(Give me some SeaFoam, Deep Creep)

Brake fluid acetone will cause rust fish oil with prevent rust wd40.

MEK is also used as a starter (cathalyst?) for fiberglass resin...it does indeed nervous system damage and causes cancer... pretty dangerous !!

Nervous system damage? Maybe BRAIN damage? Now I understand us Fiero lovers !!

quote Originally posted by Fie Ro: MEK is also used as a starter (cathalyst?) for fiberglass resin...

No! MEKP (Methyl Ethyl Ketone Peroxide), not the industrial solvent MEK (Methyl Ethyl Ketone), is what is used as a catalyst for polyester resin. They are two obviously related compounds, but they have totally different chemical properties. You generally buy MEK by the gallon (liter) and MEKP by the ounce (milliliter).

Maybe step away from the acetone fumes and try this again.

Reminded me that this thread needed a lubricating bump.

I've been using Kroil for years. Got the 2 cans for $6 deal and still can use both.

I find that this beats them all.

Yes, the famous "Blue Tipped Wrench" I hear that it can take any bolt off with minimal effort.

I've found that Fluid Film works better than any other penetrating oil I've tried.

Ah yes, I used this, works very very well.

Would be interesting to see how it would have shown up in that test with the other products.

Went and got 3 LW's today to start and engine swap. Old bolts...figure I will soak them 2 or 3 times per day until Sat and the start trying to get them off. Is there a way to set bookmarks to your favorite threads?

It wouldn't be Fluid film would it? Good stuff!! Stinky but good. -Jason

AHH!! Thats it. I actually went out and verified that's what it was but never got around to updating this post. That Fluid Film stuff works amazing. I use it on everything, lol.

I find the best thing is to use a propane torch, heat the rusted part for about 45 seconds or so, then quench it for about 20 seconds with PB Blaster. Then repeat. After 2-3 times of this, the bolt and rust damn near melt right off Just like a hot knife through butter
