It's not antifreeze. I haven't use it in years. The discoloration occurred long after the last time I used it. I have also had the algae in my white city water hoses.

Vinegar will dissolve calcium deposits in coffee pots and is recommended by Atwood to kill the sulfer odor that can occur in their water heaters. So I am leaning towards using it.
