plastic on acrylic.
now this is going to be a time consuming task.
use a small soft rag little water, go steal a tube of tooth paste and go to work. basiclly you are going to polish the windows, since acrylic is softer than glass, you can't use mechnic tools, you going to burn a hole.


good luck!

SOURCE: clear glass dishes are cloudy. What is causing it?

You can determine the cause of cloudy glassware by soaking a glass in vinegar for 5 minutes. If the cloudiness is removed it is due to hard water deposits; make sure the salt reservoir is topped up. Do not worry about over-filling it.
If the cloudiness is not removed, it is a permanent condition known as etching. In this situation, use less detergent and stop pre-washing. Dishwashing detergent needs a bit of soil to work on, otherwise it will tend to foam up.

The problem sounds like the camera did not reset properly after the last exposure. Minolta deigned the camera to keep the aperture fully open except during exposure.
During exposure it snaps the aperture down to the selected opening, then opens it again to allow enough light for proper focusing. If it did not fully open the blades after the shot, much less light would pass through the lens. The viewfinder would be darker and look murky.
Most likely cause? Dried up lubricants in the camera.
Next likely cause? Teeth broken on a plastic gear.
Get it to a camera repair place. Get estimates first.
