I purchased a steam cleaner that works far better than I expected for lots of purposes. I used it around the home on window sills, screens and a few areas on my truck. I would think if one pre-sprayed some areas with Simple Green and then blasted it with one of these steam cleaners, it would be very effective. I think I got mine off Amazon for about $80. It says it is a fabric steamer but I have not found any limitations for other uses.
Not too late to ask for one for Christmas....
