I have blackstreaks that seam to generate around or from the rubber mouldings sealing the windows. What do the experienced rv'ers out there use to clean these and/or preserve them from this happening. Is there a specific item you use. Thank you, I'm off to work now.

CW sells black plastic stick-on channel molding which you can stick over and under the windows to catch the runoff and re-direct it to someplace not so visible. Or it may just evaporate in the new channel.
I just use Simple Green to remove, then rinse well.
Saw a guy who redirected roof runoff by clipping a clothes pin to the drip point, caused it to run down the clothes pin and drip away from the vehicle. Usually it trashes the wheel arches drives me nuts.
