I would just pour in a couple of buckets of doluted bleach and can run
the pump for a few minutes with it. Would that work?

The coolant can get splashed all over while cutting. So if you just run
the pump you may not get into all the nooks and crannies on your machine.
At work they have a specially built pump and wand to spray the
disinfectant around and scrub the really dirty spots. Then they rinse
everything out.


Nothing wrong with cleaning, but everybody is just scaring you. These guys
are anaerobic, won't live long in an O2 rich area like a machine surface.
Keep the oil film off the top of the sump and give the coolant a bit of O2
daily, you won't have trouble again.
