A washing apparatus and a method of deodorizing washing water that can prevent the unpleasant smell of washing water are provided.An electrolytic water producing means 2 produces strong acidic water and strong alkaline water by electrolysis of an electrolytic solution. The produced strong acidic water and strong alkaline water are stored in an acid container 3 and alkali container 4, respectively. A mist container 5 connected to the alkali container 4 produces a deodorant mist upon receiving a part of the strong alkaline water in the alkali container 4. A discharge port 6a is selectively connected to the acid container 3, alkali container 4, or water pipe 8 so as to discharge the strong acidic water, strong alkaline water, or tap water. A mist ejection portion 7 is formed to spray the deodorant mist of the strong alkaline water in the mist container 5 around the strong acidic water or tap water discharged from the discharge port 6a so that the mist surrounds the strong acidic water or tap water.
