There should be a grommet which you’ll find (or won’t) after peeling back the wheel arch liner. If missing then you’ve got your answer as to how it got it there. Unfortunately I found the grommet hole doesn’t allow easy injection of rust protection materials unless you have some sort of lance. I then found another hole from under the car which was taped closed but allowed better access to inject waxoil into the rear sill.
Short of cutting open the sill I think it’ll be very difficult to remove the dry mud and drenching the area with oil / waxoil is probably the best you can do for the time being. When I welded mine I found a flammable polystyrene type barrier in front of the rear jacking point which would make it difficult to clean the area from the front jacking point. I never attempted to remove the chrome trim.
