Dometic fly screens - cleaning/replacing

[cgrubb99@gmail]

we bought a new van 12 months ago, there are two Dometic roof vents with sliding fly screens. These are already full of dust etc and need to removed and cleaned or replaced. But I can’t see how to do this easily and where to source replacements.

Any suggestions?

Mistake in original post - they are Fiamma vents not Dometic

I have done some screens that might be similar but post a few pictures for best response?
