I'm moving into the season where I don't use the shop everyday. Last year the coolant in the surface grinder changed into some of the most awful foul stuff you can imagine. Think curdled milk only worse. The smell was unique and permeated the shop for a long time. I got some of it in a cut on my hand and it festered.
I just bought two aerator (fish tank) pumps to run in the CNC lathe and surface grinder. Also bought a gallon of biocide for coolant. I'll plan on putting in this as called for by the label.
I was looking at another product for keeping the coolant from going foul. It increases the Ph of the solution. So, would it be a good idea to add a pinch of drain cleaner or purple degreaser to the coolant? Would this harm any of the equipment?
I want to do EVERYTHING to avoid a repeat of last year.
