I do not have a link to it, but read it, and this is how I clean my SAK's (used bought new or bought used and filthy):
1. Open all the blades, tools, etc. Remove toothpick, tweezers, corkscrew driver, pen, pin, etc.
2. Wash in warm to lukewarm water with degreaser dish detergent, i.e. Dawn.
3. Let soak for 1 hour or so.
4. Use Q-tip swabs and pipe cleaners to clean inside the knife and wherever blades fold for storage.
5. If really dirty, use a tooth brush. An M16 or M4 rifle cleaning kit has an excellent "toothbrush" that I use for this.
6. Dry. Terry cloth first, then air.
7. Oil joints. Wipe off excess.
8. Polish blades and scales with Dremel tool using stainless steel cleaner; scales with platic buffer cleaner. Found in auto parts stores (i.e. Autozone). I use the Dremel tool with the "cotton" polishing wheel, NOT stone grit wheel. Use FINE steel wool and FINE 1500 grit sand paper to smooth and polish scales. Use fine car wax to make scales like new again, i.e. McGuires. Turtle Wax is opsolete.
