Washing is one way of cleaning, namely with water and often some kind of soap or detergent. Washing is an essential part of good hygiene.
Soap assists in the reduction of oils and dirt particles so they can be washed away.
People usually wash themselves. Little children and sick and disabled people may be washed by someone else. For fun lovers etc. may wash each other.
Often a shower is used, and/or a bathtub.
More frequent is washing of just the hands, e.g. before and after preparing food and eating, after using the toilet, after handling something dirty, etc.
