Clorox Greenworks toilet cleaner

Another product I will buy is Clorox Greenworks Natural Toilet Bowl Cleaner.  I don't want to use harsh chemicals and neither a vinegar soak nor a special scrubber were working to get the rings out of the toilet, so I checked reviews for natural cleaners.  Clorox Greenworks Natural Toilet Bowl Cleaner worked best and has worked great for me, too.
