lens cleaning liquid

[PaulC (Paul Colbert)]

HI! I'd like to ask particulary the vintage collector members about lens / prism cleaning. what are the best / useful fluid ? aceton? hydrogen peroxide 3% for fungus removal? lens pen for fast and daily cleaner?

Luckily I've not had to deal with fungus but I find Zeiss lens wipes to work well for general cleaning.

Another vote for Zeiss lens wipes. Photographic film cleaner is good too (it's just aerosolised alcohol. Just keep in mind most lenses are glued, anything too aggressive just risks softening / dissolving glue.

For mirrors - distilled (or in my case filtered water) - with tiny bit of dish detergent.

UV will kill fungus, removing it is tricky if it's into the coatings.

Professionals clean less than you might think!
