WD40 is great for cleaning the machine, vises etc. I buy it in gallon cans, and put it into spray bottles. It's really bad for cleaning TTS tool shanks, as it does leave an oily/waxy residue. I've found the best thing for cleaning TTS tool shanks is Acetone - does a great job of removing oil and grease, and leaves no residue at all.
