I've done it. If your track is REALLY gunked up it will get it off.
They used ATF to clean a lot of things in the auto plants.
That being said, use it as a cleaner only. Yup every thing will slip
ofter applying. NEXT step is to clean it up with some WD40 to remove
the ATF.
Due to the weather up here my super streets track became rusty.
I leave the window open and the humidity just had a field day.
The only thing that worked for me was the ATF WD40 method.
I would not do this on a regular basis but it saved me from having to tear up
the track....
Let the grumbling begin...
Bruce..
Stop using WD-40 as well. It's bad stuff. Sure, it works great for getting that stuck bolt loose, but it will also cause rust. I had several metal things that got rusty and I would clean with WD-40. Then I was told about how it causes rust and I stopped using it, making sure I cleaned the items with soap and water to get all the WD-40 off. My metal items never rusted again.
