Hi, I'm not entirely sure if this is the right place to ask this, but I have a slight problem. I went camping with some friends just the other weekend, and brought along the old Swiss Army. It was a great trip, and I know for sure that I need to go again as soon as possible, but, in the course of cooking the supper, I managed to spill about half a can of soup all over my Victorinox. Now all the blades have a thick residue all over them, and it doesn't openm as smoothly as it used to. Any ideas as to the best way to clean it all out? I've had this baby for a good six years, and I want to be as gentle as possible, so it can last even longer. Thank you for any help.
