Hi folks. Just a quick introduction for myself, I'm new to the forum but not at all new to trains or OGR magazine. I've been in the hobby since I was about 3 years old. I have a Lionel collection that spans the years from from pre war to modern era. My collection is kept in my parent's basement where I have had it for the last 20 years. We never had water in the basement until Hurricane Irene came through last year and we got about a foot and a half of water down there. Unfortunately a lot of stuff ended up under water. Some post war engines and rolling stock, all my plasticville in original boxes, a lot of my original Lionel boxes. Talk about painful stuff. I finally got the chance to start going through and cleaning the trains this week (I know it should have been done months ago, but life gets in the way sometimes). I started with my 726 Berk that I don't think was under water but it sat in VERY humid conditions for several days before I was able to get it out of the basement. I pulled it apart yesterday and cleaned and lubed it and she runs like a champ. Not sure the smoke unit survived, but that's not a huge concern right now. Right now my bigger concern is the shell. I thought it had developed some mold on it from the humidity so I gently cleaned it with detergent, warm water and a soft toothbrush. Its definitely cleaner, but the spots didn't come off at all. Here's a photo of what I'm talking about; 
Now I'm thinking maybe the metal is corroding under the paint. Do you think I have any options short of repainting it? What kills me is that almost all of my engines (metal and plastic shells) have similar looking spots. Maybe I'll have more luck on the plastic shells. Thanks for any help.
