So my lenses have a… film? On them. It looks kinda like if you wipe something down with water and let it dry. I assume it’s because I use the unit so much. I’ve wiped everything down with lens paper, replaced the mirror because it had the dreaded black dot of doom (no shock, I’ve been using it a lot for a year and a half). I work entirely in hardwood and plywood.
My cuts are still taking a significant increase in power (or decrease in speed) to cut through reliably (though after the mirror change it’s still mostly within the range the laser can do, so yay improvement). So I want to clean the side lenses more thoroughly, and maybe try to get that film off. Is there a lens cleaning solution recommended for this?
