Looking for some help...

Every once in a while I come across a headlight with a slight bit of “foginess” on the inside of the lenses. This happened most recently to an NOS Marchal SEV Amplilux Headlight that I bought. A bit of a puzzle as the area behind the lenses is not sealed and air circulates freely.

I’m wondering if anyone has successfully cleared this fog and what method was used. The concern is doing something that might damage the reflector. Compressed air? Schlossing around liquid, such as water, cleaner, etc? The holes for the bulbs generally don’t give much room for maneuvering as far as wiping with Q-tips or somesuch.

All help greatly appreciated.

Cheers,
John
