Window Stains

Hi All,

I was wondering if anyone on this board knew what this was on my rear windows. One of my neighbors said it might be a bad tint on my windows. Any suggestions on how to remove these stains would be greatly appreciated. Thanks.

looks like a failed seal or improperly assembled IGU. That wont clean off.

RE: Window Stains


Bad low-e or failed seal.

This cannot be cleaned and will require replacement.

RE: Window Stains

Unfortunately, that kind of stain will be impossible to clean off. You’ll have to replace it. You can protect the glass on your windows by frosting them. If you don’t want to go all the way with window frosting, you can have them partially frosted. You won’t need to use blinds anymore.

RE: Window Stains

Its a seal failure, you need a new window. What brand of windows are they?

RE: Window Stains

patrick, how is frosting the windows providing protection?
