Well, my kitchen window got cleaned today to perfection. I have come to the conclusion that of the many blue liquid window cleaners I have used through the years, the Target Up&Up brand is the best.
I agree with you ... streaks are annoying. Especially after you JUST used a window cleaner. I don't know what they changed with the Windex formula - but I can't use it anymore, due to the streaks it now leaves. I usually have to mix any window cleaner I get with 50% ammonia. I can't use straight ammonia, because of the smell.
Bausch & Lombe eyeglass cleaners work well ... but they're too small for anything larger than a pair of glasses. lol
