Like mentioned earlier, it depends on if your trailer has clearcoat or not.
But
usually the 'black tarp marks' are not 'dirt' or 'grease', they are actually oxidation remnants from the tarp rubbing/abrading on bare aluminum. If it is a newer trailer, the tarp may have abraded through the clearcoat and hit the bare aluminum causing the same effect - but with the complication of wearing through the protective clearcoat. This can also happen with branches swaying in the breeze against your trailer...
The only way we found to remove
the black 'tarp marks' on our '55 Safari (w/o clearcoat) was to polish it. Actually, some of the panels we replaced because they had other damage as well, but unfortunately, the abrasion marks don't just wash away.
BTW, one of the ways to determine if you have clearcoat or not is to take a tiny dab of toothpaste & rub it on your aluminum - if it turns black, bare aluminum. If not it has a coating. Most Airstreams post 1963-ish have or
had some sort of clearcoat unless they have been stripped &/or polished.
