My trains have been set up in a fairly damp and unsealed space, and I've noticed some mildew spots on some of my rolling stock. These are modern plastic cars, and my K-line extruded aluminum passenger cars. What are some safe and effective ways to clean painted plastic and aluminum surfaces?
I've since sealed the layout space and installed a dehumidifier to keep the humidity below 55%, so hopefully the problem will not recur.

What you have is mold. Mildew is a plant related fungi that occurs on tobacco and potatoes. That being said, the fungicide I am most familiar with is by a medical company, Steris. They make a fungicide called Spore-cleanse. We used it in a bioburden controlled clean room when we made medical implants.
I have not tried this fungicide on any painted plastics or aluminum (to inspect for potential damage) but it is the only cleaner of this kind I know of.

I use a paper towel wetted with an ammoniated window cleaner.

Ok, mold - I stand corrected!
I’ll try a paper towel with Windex, thanks.
