Cleaning V2 Lens

Cameras
1

Im using my V2 outdoors in an enclosure but the lens is exposed to the elements. Its been there for a while and Im thinking it might be time to clean the lens. I’m assuming theres some kind of coating on the lens so I’m thinking just water and a microfiber cloth to clean it. Anyone have any tips/ suggestions?

Thanks

For what I’ve seen and done, it’s a plastic cover over the lens. I use 70% rubbing alcohol and a lint free surgical huck towel.

In the winter I wipe RainX on the lens and buff it. Never an issue in 2 years.
