Cleaning Aluminum Framed Windows
I'm trying to clean the black spots that have built up in the space between my aluminum-framed windows with two panes of glass that slide separately (though I'm not sure you'd call them storm windows?) My problem is that on all of the windows there is only one portion that lifts out of the frame (generally the right side, but on the picture windows the frames on either side of the center move). However, in another portion of the window with the two layers of glass both inside and outside layers seem to be fixed in the frame, as they don't slide back and forth. Is there an easy or recommended way to get into the space between those fixed panes of glass?
