When the driver's mirror on my 98 E300 went bad (got all brownish looking from the stuff that was in there), I simply affixed a new mirror over the old mirror. Problem solved.

But the brown stuff has leaked out and stained the door...there's an unsightly ark brown streak running all the way down the door. As it happened overnight, I thought I'd simply be able to wipe it off. No such luck.

Any ideas as to how to remove this stuff without damaging the paint? I tried carefully scraping away a small section of it with my thumbnail and the paint beneath is discolored...so perhaps the damage is already done.

My worst case scenario is to paint over the streak....I can't see spending the money to get it done professionally.
