Marine Upholstery Problem

[Big boys toys]

Boat was in storage for two years covered with tarp, not as tight as shrink wrap but not bad. We had a pretty intense storm blowing sideways, it did wet the upholstery that I was not aware of.
Uncovered the boat a year later, mold everywhere and plenty of it.
Mixed up a what I thought was a fairly weak solution of bleach and water , tossed it into a deck sprayer and sprayed everything. Then pressure washed it. It did come out real nice and clean.
Here is where the problem arises. The upholstery is black, red, grey and white. The black, red and grey are fine the white has a very slight brown or rust color to it.
I have tried spray 9, soft scrub with bleach, and a few other cleaners but nothing touches the brown problem.
Does anyone on her have any magic tricks ???
Thank you in advance for the replies!

In my experience; sunlight has a mysterious correcting ability on white vinyl.

I had a new red towel left on the sun pad that left a terrible stain. At the end of a weekend of baking in the hot Texas sun...it was gone. Didn't touch it with any cleaning solutions. Didn't scrub.

If you want to give it another shot at cleaning and have a PC, there are Cyclo Brushes available for vinyl/leather. They can be purchased from AG as a pair or as singles elsewhere. I used them on leather seats...huge labor saver.
