Things You'll Need
Instructions
Put water in a pot and boil.
Open all the tools on the Swiss Army Knife and drop into the boiling water. The boiling water will loosen the grime that has built up on the knife.
Take the boiling pot of water off the heat after the knife has been it for one minute and pour out the hot water.
Add warm water to the pot to cool off the Swiss Army Knife. Adding cold water could crack the plastic handle because of temperature shock.
Remove the knife from the warm water and use a toothbrush to remove any grime still on the knife.
Coat the knife blades with cooking oil after the knife has been air dried. Rub off the excess oil with a paper towel.
