Carbon tetrachloride or carbon tet is a non-flammable, dense, colorless liquid which was often used as a cleaning agent in the mid 1900s, but was phased out due to safety and environmental concerns. High exposure can affect the central nervous system and cause damage to the liver and kidneys. Prolonged exposure can be fatal.
