Air compressor or compressed air VERTICALLY is fine if you are not doing a full restore (and you are in a dirty area anyway).. followed by bleach-white/simple green/mean green/your favorite cleaner + q-tip for getting anything that sticks.
By the way, Jeri is a genius but man thats a mess!! LOL, I doubt it would harm though.. (you use freeze spray on top to remove Mylar with inserts below it anyway)
