Where to dispose of used coolant?

@PJB

I used to just put it in a jug and throw it in the garbage can. With automated pickup nobody knows wtf is in the can, could be bodies but they dont know where it came from.

And actually Ive seen notices on abandoned houses that say they put antifreeze in the sinks and toilets to prevent the pipes from freezing.

That might be RV Antifreeze though…
