Cleaning the faded panels in a polypropylene greenhouse?
I have a greenhouse with polypropylene instead of glass. This has faded in the sunlight and become opaque. How can I get it clear again?

You can't. It's an irreeversible chemical reaction caused by Ultra-violet light from the sun. The company that made this used cheap polypropylene. They should have used polypropylene with UV inhibitors added. If you can replace individual panels look for the better UV-resistant polypropylene.
