Sorry to hear you have to deal with this....I have been there too back in 2011 we had a tornado here and my model room lost a few windows. Wind and rain,etc. came in had to toss out many old boxes,instructions,decals and a lot of them need parts now and repairs. I would not put them on a radiator might not be good one the plastic...I used a blowgun and a air compressor on very low pressure to dry them out carefully.
