Switched from flood coolant to MQL after a messy Tuesday

I ran a 40-hour week with flood coolant on a 3-axis mill and spent more time wiping down the enclosure and dealing with slippery floor mats than actually cutting parts. A fellow operator in my shop kept pushing minimum quantity lubrication, so I tried it on a batch of 200 aluminum brackets and the finish came out cleaner with zero cleanup. Has anyone else made the jump and found their tool life actually improved, or was I just lucky with the alloy?
