    Looks like a lot of calcium deposit. Scrape off as much as you can with a putty knife. Then soak some paper towels with straight vinegar and squeeze them into the area, let it sit for at least an hour. Then use a tooth brush dipped in vinegar and scrub the area. You can also use hydrogen peroxide for more stubborn areas.

    You could try toilet bowl cleaner. Pour it on generously and let it set about 15 min, then scrub with a magic eraser or wadded up aluminum foil.

    Found this online hope it helps. Are you trying to clean the aluminum or the glass or both? And, what are you trying to remove? If it is water spots, i.e. mineral deposits on the glass or aluminum I would try CLR. Failing that, on the glass only, I would try Amway Chrome and Glass. It takes some elbow grease but it will do a beautiful job. If the aluminum is the issue don't use any abrasives. The material is anodized. Removal of that finish will allow corrosion to start and you will really have a mess. If it is already corroded, try mineral spirits and 0000 steel wool. After you have the corrosion cleaned put something on it to protect the metal. Clear lacquer is one thing that could work but you really should protect it with something as it will just keep corroding if you don't.
