The before and after on my CNC coolant change blew my mind

I finally swapped out the old smoky coolant in my Haas last week after putting it off for about 6 months. It went from this nasty brown sludge that smelled like a rotten egg farm to crystal clear blue water in about 20 minutes. The cut quality difference on my aluminum parts was night and day, no more chatter or weird finish marks. Has anyone else seen that big a jump just from changing the coolant mix?

Didn't think coolant mattered that much until I tried it myself.

Oh boy, @lee.lucas, you just discovered the secret sauce of not blowing up your engine. Yeah, I used to think coolant was just fancy water until my buddy's car overheated on the highway and turned into a lawn ornament. That stuff does matter, a lot. It's like finding out that the little paper thingy in your shoe actually stops blisters. Welcome to the club of people who now check their fluids before road trips instead of just crossing their fingers.
