Noticed a shift in how shops handle coolant maintenance lately

Three years ago, the place I worked at in Dayton just topped off the sump and called it good. Last month, a new foreman started a weekly pH and concentration check with a refractometer. The parts are coming out cleaner, and the machines smell better. How often does your shop actually test the coolant?

That "special, rusty perfume" just means the coolant is working hard and saving you a ton of time.

Weekly checks? We're lucky if someone remembers to add water when the tank starts looking like a science project. Maybe that's why our parts always have that special, rusty perfume.
