The pool sweep in my pool has frequently sprayed water onto my windows and glass sliding doors. How can I safely remove the stains that have accumulated on the glass?

If they are hard water stains on glass - I would try Limeaway. You spray it on and let it work for a few minutes and calcium deposits will simply disolve. You have to be careful what you use it on though because its pretty caustic and you really need to wear rubber gloves.
