Curious what effect the ATF-Acetone blend would have on painted surfaces...
did a little brief research and discovered that the only real concern seems to be the acetone reaction with rubber/plastic... seems like a good option to have in your arsenal but when using it I'd keep a bottle of clean water for rinsing off the surface after A-A application has freed the fastener just to be safe.
*note some folks are using power steering fluid- acetone... of course most PS fluids are just ATF fluids in a different application lol

Yeah I wouldn't want that mixture on my skin or anything other than the rusted bolts. Think I'll just stick with Liquid Wrench, since it looks pretty good, and I don't live in a very rusty area.

is anyone reading the contents of the product??
for example wd 40 was designed to dissipate moisture and is a water based product !!! not rust
any lubricant mixed with a solvent can be use to minimize the rust or to lose some rust thats why acetone and atf works be careful with mixinga cids and solvents. the best way is to prevent it with a good slicone based or petroleum based product and a cleaning schedule for that risky areas in your car.

i have used the ATF and Acetone on a 72 Jaguar XJ6--worked pretty good but--some of those parts on the jag (i think) were engineered to RUST WELD together. I had mine in a plastic squeeze bottle and eventually all the Acetone evaporated throug the soft plastic

I've also heard about using used brake fluid (or brake fluid mixed with water) for extreme cases.
Note: do NOT go mixing brake fluid with solvents or petroleum-based products! There are gasses and explosions involved that will put you in the grave.

That mousemilk is the shiznet but it's not really for freeing up rusted components. For maintenance and prevention on small parts it's a go to product. For freeing up rusted parts you almost need something in a pressure or spray bottle to help drive the product through the surface rust crust lol...
