I'm surprised that I didn't have this happen to me when I lived in Chicago, for years the last thing I would do, was to wash the bike, then put it in the back of the garage until April or so .
After 10 years of doing this, I changed my routine, I would take the bike out and put about 10 miles on it after washing it .
I know I caused an early demise of the brake master cylinder because of this, didn't get 10 years until it started leaking .
