Jack Mayer Posted March 18, 2015 Report Share Posted March 18, 2015 Skip Tamm sent this to me and asked me to post it. I posted it here instead of the HDT forum since I thought it generally applicable. Interesting results and consistent with what I have seen in other tests. “Machinist’s Workshop” recently published information on various penetrating oils. The magazine reports they tested these products for “break out “torque” on rusted nuts and bolts. A subjective test was made of popular penetrating oils, with the unit of merit being the torque required to remove the nut from a “scientifically rusted” bolt. Average torque load to loosen nut: No Oil used ……………………516 foot poundsWD-40 ………………… ……..238 foot poundsPB Blaster …………………….214 foot poundsLiquid Wrench ………………….127 foot poundsKano Kroil …………………….106 foot poundsATF/Acetone mix…………………. 53 foot pounds The ATF/Acetone mix is a “home brew” mix of 50/50 automatic transmission fluid and acetone. Note this “home brew” released bolts 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 20% of the price. ATF/Acetone mix is best, but you can also use ATF and lacquer thinner in a50/50 mix. ATF = Any type of Automatic Transmission Fluid. This version of the story was in one of the Military Vehicle Club newsletters.

DuffMan Posted March 18, 2015 Report Share Posted March 18, 2015 How do they produce "scientifically rusted" nuts/bolts? Did they make up say 200 and test 50 for the "no oil" to set a baseline & look for deviations? Then how many did they do for each product to minimize the effect of baseline variations? Like everything - the devil is in the details. Bottom line - if they threw a bunch in a bucket of saltwater until they looked rusted and did one bolt each - the results are meaningless.

Jimalberta Posted March 18, 2015 Report Share Posted March 18, 2015 I am part of the antique and classic car scene. When we are taking apart a sixty year old car it can get pretty difficult. So a good test for the above products is tested very well and the results are pretty much as posted.

RBH Posted March 18, 2015 Report Share Posted March 18, 2015 After years of working on cars in the rust belt, the best I have found is beeswax. You simply warm the part with a propane torch, doesn't have to be hot, and melt some beeswax onto the rusted fitting. I was skeptical at first but it is amazing how well it works.

BooneDocks Posted March 18, 2015 Report Share Posted March 18, 2015 I'll use the liquid wrench rather than extremely flammable and fume laden acetone. Actually I like Corrosion X.

Jack Mayer Posted March 19, 2015 Author Report Share Posted March 19, 2015 Hey, I'm just posting info I found interesting. I've read several "tests" that reached the same conclusion - several by people that were skeptical of the ATF/Acetone mix. But if you don't believe it then keep doing what you do now....I know I'll keep using my liquid wrench...because I have it. It is valid to be concerned about flammability. But consider how flammable some of these other products are. Jack & Danielle Mayer #60376 Lifetime Member Living on the road since 2000PLEASE no PM's.

I am sorry if you felt I was somehow concerned about one of "your" recommendations. I appreciate you posting the study results. I was only expressing my reservations with the "winner" of the study as for me and me only I have always viewed acetone as a substance a bit too volatile for my tastes.

Bill Joyce Posted March 19, 2015 Report Share Posted March 19, 2015 "I have always viewed acetone as a substance a bit too volatile for my tastes." Don't get near methylene chloride (also called Dichloromethane or DCM), since it is more volatile than acetone. It will also put insects to sleep instantly, which I found useful as an ignorant youth dealing with wasp nests. 2004 40' Newmar Dutch Star DP towing an AWD 2020 Ford Escape Hybrid, Fulltimer July 2003 to October 2018, Parttimer now.

skp51443 Posted March 20, 2015 Report Share Posted March 20, 2015 I seem to always find a use for acetone and if my can is empty I just borrow a splash of the wife's nail polish remover that is acetone with something flowery added to mask the smell. Mixing up a few drops of trans fluid and acetone for a nut really sounds good compared to having to keep one of the other good options available as rarely as I need something.

Mariner Posted March 20, 2015 Report Share Posted March 20, 2015 I've been trying for over a year to remove two bolts from under my rear bumper. I've tried a couple that're on Jack's list to no avail. I"ll be trying the acetone today.

Jack Mayer Posted March 20, 2015 Author Report Share Posted March 20, 2015 Mariner - an interesting experiment. Please report back. But if it is that stubborn then it likely will not come off. You will have to cut it off, or heat it. Jack & Danielle Mayer #60376 Lifetime Member Living on the road since 2000PLEASE no PM's.

Jimalberta Posted March 20, 2015 Report Share Posted March 20, 2015 For really rusted bolts I use an acetylene torch and get it red hot , spray it with a penetrating oil of choice, let it cool a bit and apply wrench. <p>....JIM and LINDA......2001 American Eagle 40 '.towing a GMC Sierra 1500 4X4 with RZR in the rear. 1999 JEEP Cherokee that we tow as well.

Alie&Jim's Carrilite Posted March 21, 2015 Report Share Posted March 21, 2015 The Acetone and ATF works wonders in the marine world. Acetone will wick into the smallest micron size cracks and break the bond. The ATF then lubricates the metal surfaces decreasing the friction letting the 2 parts move against each other. Acetone vapor is heavier than air, so don't let it trap in a low area. A small bottle/can like the size of a PVC glue can will last awhile if you seal it when not using it. The ATF will remain but the Acetone may evaporate out, but you can add back to it.

Alie&Jim's Carrilite Posted March 21, 2015 Report Share Posted March 21, 2015 WD-40 is great for removing stickers, and dealer logo's off of vehicles. It removes all the glue with little effort.

Bob Cochran Posted March 21, 2015 Report Share Posted March 21, 2015 I personally have used and still do Kroil successfully. WD40 for removing decals and such. PB Blaster I have some as well. So I have tried and have on hand a lot of stuff. I will use the ATF and acetone next when I have a need for such. Of course torch or nut spliter always works if they can be used and not destroy something else unintentionally in the process. 2019 Thor Chateau 28E on a Ford E450 chassis.

Mariner Posted March 21, 2015 Report Share Posted March 21, 2015 Well Acetone/ATF didn't do it for me. Put it on liberally twice with a couple hours in between applications. I guess it's going to be the torch for me. Fulltiming since 2010 2000 Dutch Star 2009 Saturn Vue Myrtle Beach, SC Link to comment Share on other sites More sharing options...

The splitter has to be harder than the nut you are trying to remove.

mickhoss Posted March 28, 2015 Report Share Posted March 28, 2015 kroil was the lubricant of choice for the fitters working on the turbines at the power stations in my area that I worked at, it was very expensive down here in oz for a 44 gallon drum and I think the power stations were one of the few places that had it and still do as they are owned and run by the state government and the procuring officers couldn't give a stuff about the price and just ordered it. we even had the the alumina refinery in the area ring the power station hierarchy wanting to buy 20litres of it because they desperately needed some and didn't want to spring for a 44gallon drum full It is excellent stuff and worked well on those big bolts that held the turbines together I will have to give the atf and acetone a go sometime. mick Link to comment Share on other sites More sharing options...
