Hydrogen peroxide is also a mold destroyer. I would try regular household chlorine bleach. What is it that is rusting? Painting over exposed metal will keep it from rusting. I don't really understand where you are getting rust.
I am not sure about the seals, but bleach kills mould on most anything. But it may be harmful to your seals. I suggest to try bleach on a little area and clean it off. Then look at it after a day or two and see if there is any damage. If it looks OK, use it on the rest of the area.
