How does a permanent marker destroy a camera lens?

Permanent markers aren't really "permanent", next time you want to get permanent marker off a (smooth) surface just colour over it with a white board marker and then wipe it off with a cloth. Even if you used a scribe and permanently damaged the front element, they are replaceable. (They are made that way as the front element is prone to damage). Even so, quality SLR lenses are completely dismantlable, so if you damaged any of the internals they can be repaired/replaced.

Cheers Phil

I was going to reply with the same sentiments but I have never tried the white board markers, I was going to suggest alcohol which does not damage the lens either.
Next time I need to remove a "permanent" marker I'll try your method.

Thanks Phil & Tony. I haven't taken the risk with mine as bought replacable protectors: screw on screw off, no labour costs. I have used white board & permanent markers on a household notice/reminder board and all colours have become impossible (so far) to remove. Then again I think the white board was melamine : maybe laminex is better but way dearer.Tried alcohol which didn't work : I was thinking of trying wd40 or crc as it is useless anyway: these work on sticky glue residue on plastic as does "Oomph" somewhat like graffetti remover.

GooGone works for a white board but I hate using that stuff. I use acetone if nothing else works, that never fails.
