Washing out mouth with soap

Washing out mouth with soap is meant to be unpleasant, but is usually not intended to cause death or serious harm. Nonetheless, many people employ the aforementioned techniques with extremely limited knowledge regarding the safety of ingesting their chosen cleansing agents. Agents likely to cause serious harm if swallowed include many automatic dishwasher detergents and laundry detergents. Even ordinary bar soaps and liquid hand soaps may cause harmful effects including vomiting, diarrhea, irritation of the lining of the mouth and digestive tract, and in rare instances, pulmonary aspiration. This is especially true if these products are ingested in large quantities.
