A process for sanitizing and cleaning wherein water containing ozone and other substances is sprayed through a spray head. The spray head contains a mixing chamber wherein ozone and other chemicals are mixed prior to being sprayed. The spray head also imparts an electrostatic charge onto the water or cleaning solution prior to be emitted from the spray head. Ozone is drawn into the spray head from an ozone generator through a tube positioned near the mixing chamber. The ozone generator may further comprise orienting at least one port on both a first and a second Venturi in the interior of the ozone generator to enhance the process of ozone production. A halogen generator may be incorporated into the process to add a sanitizing halogen to the water or cleaning solution.
