A toilet seat is cleaned and sanitized by directing first liquid and then gas thereagainst from a hose. A switch is closed when a toliet seat cover is closed to initiate operation of a liquid system and a timer is included to shut off the liquid system. The liquid system is connected to a gas system to initiate operation of the gas system after the liquid system is shut down, and the gas system is connected to the switch to re-set that switch when the gas system is shut down. Both the liquid and the gas system are connected to the hose and valves are included to prevent intermingling of the fluids. The toilet seat includes a groove and the cover includes a tongue on a flange that mates with the groove to seal the cover to the seat in a fluid-tight manner.
