[decimal86]

folks

i have 2 of these and over the years have seen water stains on the lens. it does not affect the picture quality (i think...) but just how do i get them stains off?

appreciate your help.

water with vinegar might help soften the mineral crystal that have formed. Try soaking in dilute solution for a few hours
