Jo Ann,
You used SCOTCH BRITE pads on your window?
Have you ever seen the cutting edges on those types of pads? They are not
meant for glass and most likely you now can see 'rings' or 'halos' at night
when light shines through them.
Also, if you used the Scotch Brite pads on aluminum - well you scratched
that surface too. And neither the glass nor the metal will 'heal' itself of
the marks.
Use a not marking (softer than the material you are working on) scraper such
as hard wood scrap beveled into a scraper, etc. But never would I use
Scotch Brite pads unless my intent was to intentionally leave a design in
metal or glass. And you can make decorations on metal with a small piece of
Scotch Brite spinning fastly under a rubber sanding pad attached to a drill
motor.
