Norb..next year, get one of those packs that West Marine sells that give off a gas to inhibit mold. I put several aboard over the winter and they seem to do the job. In the spring, I am not mildew-free. But what's there is quite minor and I use the same formula Jeff does, a couple of tablespoons of clorox in a gal of water w/ a drop or two of dishwashing detergent. Just sponge over the whole interior once a season and perhaps a touch up mid-season. Some mildew spores hide pretty well until high summer humidity sets them on the prowl.
