Can the steam produced by the Optima Steamer clean a very dirty car?

Yes, the Optima Steamer generates high temperature and relatively low pressure steam (ca. 8 bars) but powerful enough to remove all kind of dirt of any surfaces. Instead of cleaning by high pressure water the Optima Steamer uses the heat to lifts up dirt and mud from the car surface quickly and effectively. In addition the Optima Steamer has a moisture control valve that allows the operator to increase or decrease the moisture content. Wet steam is used to clean heavily soiled part of the vehicle meanwhile dry vapor steam sanitizes and refreshes interiors.
