Leaving potable antifreeze in the system
I haven't used my TC since last fall so now it's been a year since I filled the water system with potable antifreeze. And I have no plans to use the TC until next spring at the earliest....when a Covid-19 vaccine is available.
Do I need to change it since it's a year old?
