Ring lens film/cleaner

So I didn't realize there was a plastic film over the lens when I installed it. Now it has deteriorated, peel and cracked. I removed as much as I could but there is still some bits left and what appears to be a scratch or adhesive left. My question, is there a solvent or cleaner I can use on the lens to get the remainder of the film off, or the adhesive cleared? I was wondering if GooGone or Acetone could be used, I would hope the lens was glass and could be cleaned. I've included a picture you can see the cloudy portions on the upper left and lower right. Thanks in advance.
