Was it one of those spills that gets into everything and you're finding little oily spots for days? That's when you realize a proper recycling setup isn't just about being green... it saves you from the huge headache of cleaning up hazardous waste yourself. A good shop will test your old coolant, clean out all the contaminants, and give you back a batch that meets spec. It turns a total mess into a closed loop so it literally can't spill like that again.
Totally feel that, had a similar mess in my old shop van. That stuff gets into every crack and you're slipping on it for a month, lmao. Sending it out to be cleaned up and reused just makes the whole job way less of a nightmare. Once you get the system down, you're not constantly buying new jugs and dealing with the disposal panic.
