I've heard this several times but just never took the time to 'brew some up' to check out. I'll try it myself one of these days though! At least you'd have a large volume to work with...
it might work on the theory that if a little does a little good then a lot will do a lot of good
I've read that small batches are recommended since acetone evaporates so rapidly.
My understanding is that the acetone helps the mixture penetrate...and then evaporates, leaving the PS fluid behind to do the trick.
I haven't tried it yet but I intend to...I just bought a gallon of acetone from Lowes....and I have lots of PS fliud on the shelf...I'm just looking for a problem to try it on.
The site that did the testing first reported the mix was trans fluid and acetone....but before they could correct the error, the internet exploded with stories that parroted that error. Many complained that the mix just refused to mix...sort of an oil and water type thing. Anyway...I found the original and they made the correction.
On a side-note...I've found kerosene to be the most effective and economical grease and oil solvent.
I recently had to fix a blown head gasket on a greasy engine and since it's cold out, I couldn't use the garden hose to wash away the Foamy Engine Brite...and multiple cans of brake cleaner spray could get expensive...so I tried the kerosene. I love it! And I've been able to use it over and over...I just filter the solids.
Great to clean the grease off the hands as well.
In the past I've used old stale gas for cleaning parts and as an initial hand cleaner...not sure what else could be done with it.
