Both acids and bases function as cleaning agents, as they have the ability to erode stains and other dirt from surfaces. Soap is an example of a base.

Acids are present in the stomach and are used to dissolve swallowed food so it can be absorbed. People with stomachs that produce too much acid can take antacids, which are basically bases intended to neutralize the acid.
