Cleaning bino housing?

[Weldor]

Anyone have a way to clean or remove graying or whitish film on the outside of bino's? My Zeiss Are a few years old seems like each year after storing them between season's they have a whitish film on the rubber coating.

The better quality automotive interior detailing products are gentle on rubber/plastic and don’t leave behind a thick greasy mess, but there’s enough oil left behind surfaces don’t look dry. Meguire interior detailer is what I use for most things.
