Easy! I use a wet Swiffer cloth on my Swiffer pole and a squeegee. Done in no time. But don't wash them when the sun is hitting them, that's when you'll get streaks.

Sponge soaked in warm water with some dishwashing liquid and then squeegee off. You definitely need a good squeegee, not a cheap one designed for showers. You can find them easily in home improvement stores.

Thank you. I just tried the swiiffer method but my cheap squeegee left streaks. I will go to Home Depot and get a new one. I need it for all my windows anyway.

Always wipe the squeegee dry with a cloth after each swipe.

Thanks! I did that but it was a cheap squeegee and left lines even after drying.

Buy Ettore squeegees. Pro style works very well.

Thank you.

I too just use hot water and a microfiber cloth just make sure the cloth has never has fabric softener near it in fct i buy the ones from Costco they are really affordable and when doing glass I just take out a new one . I use them for almost everrthing , dish rags , cleaning cloths polishing chrome , they are awesome for stainless best investment you will make for dusting and cleaning.When they stop performing properly I take them out to my horse and use them for grooming him.

Great idea. II have the cloths. Thanks.
