Abstract: The present invention provides a low pressure and low temperature steam cleaner for washing vehicles. A vaporizing unit which vaporizes water at low temperature and low pressure is used to supply steam through a delivery device, such as a wand, to clean a car.

Because the steam is supplied at low temperature and pressure, very little water and/or chemicals are needed, and the propensity of damaging the car's finish is reduced. For similar reasons, one can use the same device to clean the interior of the car (including generally water-averse materials such as fabrics and leather), thus, providing the above described advantages.

Abstract: Only a small useful quantity of washing water as close as possible to the spray nozzles of the windshield wiper system is heated. As a result of corresponding miniaturization, the heating time can be reduced to 5 to 10 seconds. A sufficient cleaning effect can be achieved in most cases by hot water after the windshield spray system is actuated two or three times.

The water is heated via an instant heating element which, with a content of, for example, 10 to 50 cm.sup.3, can be installed even in a secondary chamber. Some of the heat energy is therefore stored in a larger thermal reserve tank of, for example, 1 dl.
