First, I washed the windows with soapy water, then wiped it away and washed again with regular clear water. It left the windows pretty much clean, but not very shiny.
For shiny windows, I made a solution of 2\3 water and 1\3 vinegar. I sprayed my windows with this solution, wiped it off with a clean cloth and then polished with some old newspapers.
I've read about this method on one of the frugal living websites I found through Google. I wish I could remember which, so I'd give them the credit! Anyway, I was very pleased, for a number of reasons:
1. It worked better than any commerical spray I tried before.
2. It's cheaper than any spray I could find, even with all the spring discounts on cleaning agents.
3. Minimizing contact with chemicals is better for our health and for the environment.
Anyway, I became a real vinegar fan now! Looking forward for more cleaning tips from you.
