Re: Mold = town in North Wales. No need to destroy it! (nm)
Having passed through it I can understand why.

Starbrite do a good product for mildew on headlinings
I think it is bleach based so may be a problem if used on fabric seating but should be ok on leather/PVC.
One good thing to reduce mould growth is to use dessicator crystals. They cost £6 or 7 from Woolworths and include a plastic box which fills with water.
Two of these on a 30 footer have eliminated mildew over the winter period.
I have had good luck with the compounds they sell for removing black algae from swimming pools or spas. Some work with just a teaspoon full per gallon of water, or some make a paste that you can spread on really stubborn outbreaks. Make sure you check a small spot first if there are colours or fabrics that might suffer.
Here is a link to some information that may help (USA products but).
Sainsburys sell a spray on "Mold and Mildew" remover I use it on PVC cushion covers and non fabric sufaces, it works very well,spray on leave for about 10-15 minutes, rinse off. Be sure to wear protective gloves. Trevor
