I just bought my Ray Ban Meta Gen 2 with grey transition lenses. They were smudged with oil and fingerprints out of the box. So as I usually do for all my electronics, I sprayed a bit of 99.9% isopropyl alcohol all over the glasses and wiped them off immediately with a tissue. It cleaned the glass, but for some weird reason, it has left a lot of stains all over the frame as can be seen in the pictures. This is the first time something like this has ever happened with the isopropyl alcohol.

Can someone please explain why this would happen and how I can clean off these ugly looking stains from the frames? Isopropyl alcohol surely isn’t doing the trick :((
