Penetrating Oils

[RBridenbaugh]

I'm changing out my front upper/lower ball joints and the axle and driveline u-joints within the next month. I still need to get a big brass hammer to help things come loose. To make it easier I've been spraying the various areas with penetrating oil every couple of days.



So it was very interesting to see this post from over on RV.net



"Here's some interesting test data on rust busters.



"The April/May 2007 edition of Machinist's Workshop did a test of penetrating oils where they measured the force required to loosen rusty test devices. Buy the issue if you want to see how they did the test. The results reported were interesting. The lower the number of pounds the better. Mighty interesting results for simple acetone and transmission fluid!



Penetrating oil . Average load . . Price per fluid ounce

None ... ... ... ... ..... 516 pounds .

WD-40 ... ... ... ..... 238 pounds . . $0. 25

PB Blaster ... ... ... 214 pounds . . $0. 35

Liquid Wrench ... 127 pounds . . $0. 21

Kano Kroil ... ..... 106 pounds . . $0. 75

ATF-Acetone mix. . 53 pounds . . $0. 10



The ATF-Acetone mix was a 50/50 mix (1 to 1 ratio). "

I've seen this posted in other forums. It's pretty interesting, but I always forget to try the ATF/Acetone mixture.

Truth be told, I've had mostly poor experience with penetrating oils. Lately I've been polishing off a can of PB and my personal experience has been that the Liquid Wrench is indeed better.

I've been using Kroil for may years now--it has never let me down in areas that I cannot heat with a torch. It is a VERY EFFECTIVE penetrating oil. They now send me a brochure very year that has a2 for 1 special. Somehting like two 15 oz cans for 15. 95 plus s/h.

Still, the 50/50 acetone/atf mix sounds great!!! I'll have to try it soon.

Best penetrating fluid you will ever use is equal

Parts of(I use I litre of each,keep on sealed tin

Cpntainer) acetone,ATf,mineral spirits,and diesel.

Much cheaper than aerosols... soak as long as possible



Use squirt botte... ... ... ... Lasts a long time.

I've always had good luck with Amsoil MP penetrating oil. I just tried Kroil for the first time a couple weeks ago at a friends house when helping his grandson do a disc brake conversion on a '65 Mustang. It seems to work well.

My compliments to you guys that come up with these unusual "cocktails" that work better than what is available on the market. When you consider that these companies probably have chemists that come up with these products & they don't work as well as what you guys come up with, is amazing, to me.



One of the other things that actual truck owners came up with that is better than what the factory engineers & builds is the truck seats. The stock seats were killing me after about an hour & a half of driving. Members, here, came up with a fix that works very well. I modified the 'fix' a bit, & my seats are very comfprtable, now. I can drive all day without my right leg aching.



Keep up the good work. I learn a lot from you guys.



Thanks.

This is great info. Thanks RBridenbaugh for posting it.



One of my favorite penetrating oils and lubricants is Corrosion-X. It's a popular in the aircraft industry. I know quite a few folks that swear by Kroil.

Liquid wrench or Kano kroil I had good luck with both.

I have always had superb results with Kanolabs Kroil Oil. Awesome stuff. The only thing it didn't help with... removing the front hub assy's on my truck. The torch had to take care of those.

Watch how you handle acetone, with proper PPE, I hope. It is absorbed through the skin, or breathing fumes. I used this stuff at work, in many places. Mostly for cleaning. Heres a link; ATSDR - ToxFAQs™: Acetone Have fun!, GregH

Having spent 30 years in refinery maintence, I've never found anything better than "NUTS OFF" Soaking time is the foremost element.

Let's face it: chronic exposure to anything is bad for you. Have you experienced some health problems from your use of acetone?

If I made a list of everything I was exposed to without PPE, It would probably lock-up Steve's servers:-laf.

You can have acute exposure as well as chronic. A day slopping acetone on parts with bare hands will dry out your skin in a way that will require medical attention. It will be absorbed through your skin and you could have short term issues like dizzyness. You will probably recover with no issues, but your liver will not like you and may give you fits later in life, especially if you make a habit of using chemicals without a Chemical respirator and barrier clothing.

I will not cease telling folks, KNOW your materials and KNOW your physical limitations. Your body was not made to metabolize solvents, fumes, and anything else that wasnt obviously part of eating, drinking and breathing. If you think you can get by, this time, on one issue and the next time on another issue, and so on, you will have given your body a burden it was not meant to carry and you will suffer for it in your later years! Take care of yourself, your Grandchildren will thank you! If you think you are to tuff for PPE, you are the Fool! Dont listen to the shop tuff guy. He will spend his last years as a drooling idiot! I've seen it! Respectfully, to all out there! GregH

Thanks for reminding us all about the handling of chemicals. It's so easy

to get in a hurry and avoid the gloves, etc. The cost of carelessness to fellow wrenchers will be many years lost from their favorite hobby.

After years of factory maintainance, safety glasses saved my eyes

many times.

I have used Kroil for years at work and havent found anything better yet. I will have to try the acetone/atf mix.
