I had that problem with a mirror. I finally used the spray cleaner for computer monitors (mine was from Staples) and the smears finally came right off.

Make sure you are cleaning on cloudy days, not sunny. What products are you using?

How old are they? It could be failed Low-e if they are equip with that type of coating.

They are at least 11 years old. We have tried windex, ammonia, etc. They are windows that are in a shaded area so no direct sunlight. And the one directly next to it does not look that way.
This is a rental so I wonder if the last people may have used some weird chemical to clean?

Is the streaks maybe in between the glass?

Damp microfiber cloth to wash and another to dry. Nothing else needed. That's all I ever use and no streaks even in sun.

Seal failure?

Looks like it's failed double pane glass. It gets cloudy inside, between the pane...as millworkman says: seal failure. Only cure is to replace the glass.

I was wondering about the seal failure. My only question is why it’s a perfect streak. As if someone scratched it with something when wiping.
Is that how seal failure shows up???

Are you using white paper towels to wipe the windows? They will streak from the white dye used in them. That has happened to me. Try the tan colored natural towels.

I would suggest you to try regular toothpaste to clean your windows. Put some toothpaste on a microfiber cloth and rub it in a circular motion over the streaks. I hope this will give you good results.

"See if you can ID who made the window and go about getting a warranty sash."

Or call a local glass company for about $250 they will install a new pc of insulated glass. They will measure and install it. Or if your so inclined take the sash off, have them measure the glass at their shop, reinstall the sash, when the glass is in take it to them for the new glass, should be an hour or so of work. And your done!

You shouldn't need anything chemical beyond a little soap and water-- try using a microfiber cloth

Yes, you can a use chemical-free soap and lukewarm water as well for cleaning but try only with a microfiber cloth.
