A dish washing method includes a process for applying a sticking inhibitor to the surface of dishes in order to make it easy to remove food from the surface of the dishes. The sticking inhibitor is a compound having hydrophilic and hydrophobic groups. The compound is absorbed to the surfaces of the dishes by the hydrophilic groups, and is absorbed to food surfaces by the hydrophobic groups. The compound is a compound containing a fluoroalkyl group. Also, a dish washer has a reservoir for storing therein the sticking inhibitor and a passageway for joining the sticking inhibitor with a detergent.

Method and apparatus for washing dishes, sticking inhibitor and rinsing
