Mayhems Pastel - age and disposal

[jamsomito]

I've been using Mayhems Pastel blueberry for about 2 years now, maybe a little bit longer. It still looks and cools like the day I got it, but it's getting to be time to change my tubing out. Had a couple questions:

1) How long is a reasonable length of time to have the coolant in service? Should I drain to a jug and put back in my system, or would it be a good idea to dispose and buy new?

2) It says not to just flush it down the drain. How exactly are you supposed to dispose of this stuff? I'd rather not have it just sitting around for my kids or dog to get into if it serves no use.

Assuming it's glycol-based, the corrosion resistance it provides is probably good for at least two years.

Many municipalities have a place you can take spent household chemicals like antifreeze and brake fluid to be disposed of properly.

Any oil-change station by law has to accept it from you, if you're in the US. Walmart is easily located

Anyone used Mayhems Pastel more than 2 years? It seems fine to me right now, should I just save it and add it back to the loop?
