My cleaners accidentally left some old drywall boxes in my brand new fiberglass tub causing the ink from the box to seep into the fiberglass. I tried using Clorox and a variety of other household cleaners to get it out, but nothing seems to work. I had a friend who had this problem in the past. She paid $75 to have the stain removed, so there is a solution that removes the blue stain. I just don't know what it is. Perhaps it's a mix of several things. Some have mentioned a special type hydrogen peroxide, but I have no idea where to get it from. Do you have any suggestions?

Good friends just moved into a home (built early 80's) that has older aluminum double pain windows that are VERY dirty IN BETWEEN the panes. No cleaner will get the "foggy" look off of the interior or exterior. We live in South Texas (humid...very humid) and it looks like the humidity/dirt has settled in there. ANY ideas about solutions for cleaning?? They cannot afford to replace the many windows in the house. HELP!??!
