For cleaning the louver windows on the sides facing the street, these Wypall wipes are indispensable. I spray the louvers liberally with a glass cleaner and then wipe, turn to a clean side and keep going until no more black grime shows on the towel -- if I did this with flimsy paper towels or disposable wipes, they literally start to fall apart. I can use one Wypall wipe to clean 3-4 louvered windows before the whole wipe is saturated with dirt -- it's so much easier and quicker to get all the gunk off and I don't dread cleaning those louvered windows with these wipes -- same goes for cleaning the windows on my SUV, especially the back window which always is so much dirtier -- a liberal spray of glass cleaner, a couple of swipes with one side of the Wypall wipe, another spray of glass cleaner and using the clean side of the wipe and it's done!These are a little expensive but the time and effort to clean especially dirty street grime off your glass is minimized -- worth it in my estimation.
