I have windows....lots of windows, and I hated cleaning them as they would always streak with commercial window cleaner and papertowel. Well, I got this idea from Fauve and her recipe for cleaning carpets. I cut the recipe down as I did not have a container big enough. After cleaning my carpets (and I might add, her recipe cleaned a whole lot better than the commercial stuff!!!), I used the rest of the solution on my granit counters. They came out sparkling. So onto the windows....and not a streak! So, it went from windows, cleaning mirrors, even stovetop....anything that needs to shine!!! Move over Windex....I have something better!!!
