I did a search and couldn't find anything on this.

I have a black streak coming form my door handles down the side of the car. It is real hard to get off when washing. I think its grease from inside the door that is running out when it rains. Has anybody else seen this on their cars. Also what is the best way to remove it?

Thanks

I have had this also. I used a cleaner wax to get it off the first time. My car has been sitting for a few days and it rained quite a bit. So needless to say, its back again. I will wash my car today and see how hard it is to get off from my newly waxed door.
