Question Crud reduction

Yup, that would be a problem even here in freshwater. I wonder if a roll of clear film over the sensing area(s) that periodically could be turned by motor might work. Kind of like the tear offs dirt bike racers use or more like what's used on motorsports cameras that have to operate out of the car (Indy, F1). Have big enough rolls to last a season and service them, cleaning and replacing the roll once per season ?

Or perhaps period blasts of compressed air to clean the sensing area(s) ?

Perhaps motorized wipers like my wife's cars headlights ?
