Black stains on seals around windows

[suncrest]

I have a 2001 alfa gold 5th wheel with black stains on all exterior rubber seals around windows and doors.
I have tried mold and milsew cleaners,bleach,oxyclean, all with no luck.
If anyone has any ideas please let me know.

Thanks, John.

I presume you have tried Black Streak Remover??? Get it at Wal-Mart or any RV shop....works great.
