If its just fogging that is creating the problem when you clean your double pane windows, you can congratulate yourself for a job well done.

Removing Water Residue and Stains

To address those stains inside the panes, you need two lengths of plastic tubing small enough to fit through the holes you drilled. Insert one tube into the hole on the bottom pane and secure it with putty. Make sure the tubing reaches inside the window, and that the other end is fixed enough so that it can funnel liquid into a catch. A bucket or large bowl works to catch the liquid you siphon from the bottom of the window.

From the top hole, funnel in your cleaning solution. Specialized glass cleaners or even simple ammonia and water solutions work on most window-related problems. Funnel enough liquid into the top hole to clean the window, while making sure the tubing on the bottom of the window is set up well enough to siphon out excess solution.

Finishing Touches

Once the window is satisfactorily clean, remove the tubing and let it dry for a few days. When the moisture has dissipated, cover the holes with clear packing tape and puncture to keep your windows looking great!
