How to clean (or better yet prevent) nasty buildup inside canner?
Almost new aluminum 23 qt Presto pressure canner. Used maybe 5 or 6 times.
I usually add vinegar to the tap water & although I think helps keep the jars cleaner it might be reacting with the aluminum?
Next time I can something will use distilled water instead of tap water to see if that helps.
Suggestions? I know can't use CLR to clean it. Baking soda?
