I learned about using the 50/50 mix from this site years ago and use it all the time. I always have a can of acetone here (use it to clean vintage tools and gun parts) and ATF on the shelf, so I mix up a little to use for a project and don't store it. I use an empty 8 oz. Kroil can for this purpose. It does have a cap for the spout but I tend to use the mix on a project and dump the little that is left over rather than store it.
For those who have not used acetone, it's important to note that the fumes are more volatile than gasoline. You need to use it in a well-ventilated area (outdoors is best) and not have a source of fire nearby when using it.
