Or you could run cutting oil and be done with the hassle, as I advised a few
months ago. I made the same mistake many years ago, switched and haven't
regretted it since. The fact is that as a hobby machine, we simply don't use
the machine enough to prevent this from occurring with soluable oil. If you
do not have a drain petcock on the bottom of the tank, you should install
one once the machine is cleaned.

Due neglect and mismanagement, the coolant in my lathe finally went
bad after several months in the sump. I have to add here that I have
all ingredients for setting up both the skimmer, as well as aerator,
to run on two timers, something that I plan on doing soon. But as of
now, I want to make sure that I properly remove old coolant.

As far as I understand, I should try to really get rid of the harmful
bacterias that live in the present coolant. I have a easy to use water
pump that I can use for this purpose.

So my plan was, pump out the coolant, rince the sump a couple of times
with just hot water with some Simple Green, then put water with bleach
for an hour, and rinse some more. Would that seem to be a good plan?
