Headlight polishing question

Morning everyone, I picked up a set of used clear headlights + corners for 20 bucks off kijiji. They are in pretty good shape for the price. Two problems, 1 the headlights were used with HIDs in the h1 socket (high beam) and fogged the inside. I tried to see if a small plastic straw would scrape some of it off and it did but it didn't make it clear in the spot. I know I might have to remove the lens but I want to know if I would be wasting my time attempting to do it and have no luck polishing. I know it was the HIDs because only the high beam section has gone hazy a little. Any ideas?

2 apparently the corners have a baffle inside for the Light and it melted so I am trying to figure out a way to remove it because it's just connected with 3 "feet" any ideas ?

Thanks.
