What has happened and how can I get rid of this, along with preventing it?It's not something I can remove with scrubbing or water and it's not on the surface.
The clouding is caused by multiple microfine scratches. These occur more often near the ends as these are the most exposed areas.
Isn't that cased by wear, as in it's rubbing on something.
the cloudiness is caused by UV rays from the sun.
