I use the acetone method too and it works awesome. I use a 2$ gallon paint can with a lid. you have to be careful because acetone will eat some types of plastic.
You can use the same acetone for quite a while. I wash my wheels and tires before i put them in so the acetone stays cleaner.
Acetone (used to be) the main ingredient in nail polish remover. It will take CA off your fingers pretty easily.
