Cleaning up rubber molding

So I just bought a 2015 Tacoma that was certainly stored outside. the rubber exterior molding around all the windows have raised spotting for lack of a better description. Is this UV Damage? Can it be cleaned up with any detailing product?

 

I would start with a dedicated rubber cleaner (I am currently using Adams Tire and Rubber Cleaner) and scrub like a mofo with a utility microfiber. Then I would dress with Carpro Perl. It will stay in place when it rains.

 

Walked by mine today and noticed it looked horrible. I used a Mr. Clean magic eraser and a bowl of water, then buffed out with Mothers back to black. Turned out pretty good for a quick job in 95 degree heat.
