This is going to sound wierd but I know the best cutting fluid out there and you can find it in 20 places near your home. I heard about it on the welding newsgroup from one of the premier users. He told me to go find some Zep Big Orange and put some in a spray bottle. I use that to spray down my mills and saw blades and it is totally non-toxic and easily removable, I have never stopped using it. I GMAW boat docks on weekends and this stuff is awesome and I never have contamination issues.
