Problem did not use the boat for two years.
Covered but outside, winterized correctly.
When uncovered had your typical mold problem.
Made up a bleach solution. Probably too strong although I"m not sure probably two cups in a gallon of water in the bug sprayer. Sprayed it on, it worked like a dream mold gone !
The problem I ran into was the bleach seemed to leave the white upholstery with a light orange tinge. I may have left the bleach on for that one more beer and damaged the upholstery.
Any Ideas ?

Your best bet is to leave it open to direct sunlight and let the UV rays do their job. It will get white again.

As for mold, you need to prevent it in the first place. I have kept my 292 on a lift fully covered for six years during the boating season. A small dehumidifier keeps the humidity below 50%. It drains into a condensate tank with an automatic pump to pump the water overboard. In the winter I use a few buckets of dessicant which absorbs any excess moisture. Never a mold problem and the cuddy still smells like new.
