Really the only way to to clean devices with flash is to destroy the flash.   At a very least you'll need to reflash them with the current OS.   

Here is a copy of the DOD Guidelines for every thing...

The flash answer is to use something to write to EVERY address, then erase, or just pulverize it.

Does anyone have a guide that includes sanitization information for all Cisco devices(at least switches, routers, IDS's, and ASA 5500 Series) so I don't have to recreate the wheel?
