I have some double pane windows with failed seals. They get condensation inside. When it dries it leaves unsightly residue that I can't figure out how to clean off.
I know that I could replace the windows, but that seems wasteful for what is mostly a cosmetic problem.
Are there any clever ways of cleaning between the panes? Maybe all windows should come with magnetic cleaners like they have for the inside of fish tanks.

In fact, you can clear these windows up. If its regular glass, two small holes are drilled and a cleaning solution (which need not be toxic) injected.
If it is tempered glass, the same procedure is possible if the glass seal can be reached for drilling (this is possible for most windows that can open and close: they'd get drilled from an edge). Check the glass for a frosted or white color marking showing if it is tempered.
Since this is a DIY advice site I can direct you to http://foggywindowrepairkits.com/ . The DIY kits mentioned above are over $200, and can't be rented and returned. But really you're probably better off finding a local service company that can do this, possibly with even better techniques.
