Unbeknownst by me, but mine had gone to 60 today, and must have bee high last week - but just the one complaint.
Oddly enough, her windows weren't all bad, just a few - spots at the bottom, one window with spots all over, but the rest were clear.
Weird.
I'd never think of using 60, but now I'm thinking we can get away with rainwater - if we can get enough.
