Title: Rusted bolts Post by: Ian Robinson on October 14, 2013, 10,06:18 AM Copied from another forum. Interesting result from the Acetone/ATF mixture. Molasses is good at freeing rusted parts if you have time as well
In fairness, WD-40 is not designed as a penetrator/rust release agent, it just gets used for 'everything'. Machinist's Workshop Mag recently published some information on various penetrating oils that I found very interesting. Some of you might appreciate this. The magazine reports they tested penetrates for break out torque on rusted nuts. - They arranged a subjective test of all the popular penetrates with the control being the torque required to remove the nut from a "scientifically rusted" environment. Penetrating oils Average torque load to loosen * No Oil used 516 pounds * WD-40 238 pounds * PB Blaster 214 pounds * Liquid Wrench 127 pounds * Kano Kroil 106 pounds * ATF-Acetone mix 53 pounds *** ATF=Automatic Transmission Fluid 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. Steve from Godwin-Singer says that ATF-Acetone mix is best, but you can also use ATF and lacquer thinner in a 50-50 mix, (this actually works well). Power-steering fluid also works as well as ATF!

Title: Re: Rusted bolts Post by: Ken R on October 15, 2013, 10,24:55 AM Hooray - I was peed off every time I looked at the ATF in the shed that was probably never going to get used with all the sealed auto gearboxes in cars these days. Now I can use it to free up the next rusty thingy I find.
Some thoughts - With acetone on it's own evaporating so quick, do you just mix a small amount and apply quickly, how long does the mix last. |
