Motorcycle racers use "tear aways" on their helmet visors. Thin plastic sheets that they can tear off and throw away when the visor gets too dirty.
(Not sure I'd want to deploy a system that intentionally litters single use plastics onto pristine planets though. We're already the species who spent way too long tossing old-fashioned non-biodegradable styrofoam cheeseburger containers out of 1967 Cadillac Eldorado Convertibles with whale-skin hubcaps getting 1mpg doing 110mph down the freeway...)
Might be able to use something like a toner transfer belt/blanket in a laser printer, with brushes and/or electrostatics to clean the belt as it cycles in a loop.

I mean, the alternative is littering dead rovers, so a little plastic sheet doesn't sound as bad
Arguably at least there's good purpose behind those...
<tin foil hat>And after all, they left the Pyramids and Stonehenge behind here, right???

Make it a cellophane type of substance that will dissolve in wate...oops. ;P
