RV Repair: rubber/plastic trim, black mold, camping world

Question
The exterior trim around the doors, storage compartments and windows are white and appear to be covered with black mold.  Is there a cleaner that will clean this or where can I get the replacement trim?  It is a 1995 Shasta travel trailer.

Thanks!

Answer
Hi Mary:
A company called "Applied Biochemists" makes some stuff called 'Black Streak Remover' that should do the job. You'll find it at most RV parts places or on the internet, like Camping World or NTP Distributors, www.ntpdistribution.com.. If you have to change the trim the best thing to do is call Shasta customer service.  
Good luck.
Bill
