So I have a laser I was burning stuff with, and when I tried to burn this aluminum object, the light reflected in its own lens and when i use the laser, it looks foggy. But it does work, because it burns, just the only problem being a blurry looking lens so it doesn't focus properly.

What can I do? Bought a 4.5w laser from SciFi lasers

Arcane 2.0 445nm
