A concentrated cleaning composition for cleaning outdoor painted/stained surfaces. The concentrated cleaning solution includes an aqueous chlorinated bleach solution, a surfactant, a phosphate and a silicate. The concentrated cleaning solution is diluted with water to form a diluted composition which is applied to the surfaces to be cleaned to effect loosening of soil. Thereafter, the loosened soil is removed by the mechanical action of a water spray.

A method for cleaning material such as mold, mildew, algae, dirt and/or stains from a soiled outdoor painted or artificially stained surface selected from the group consisting of brick, concrete, wood and metal, comprising the steps of: forming a diluted cleaning composition by feeding a concentrated cleaning composition from a container and water under pressure from a water hose into a mixing chamber of a spray gun attached to the container and the water hose, the concentrated cleaning composition consisting essentially of an aqueous chlorinated bleach solution and the concentrated cleaning composition having a hypochlorite content of about 3.0 to 10.0%; spraying the diluted cleaning composition from the spray gun onto the soiled surface; allowing the diluted cleaning composition to remain on the soiled surface for a period of time sufficient to loosen material to be removed from the soiled surface; and removing the loosened material together with the diluted cleaning composition from the soiled surface by spraying rinsing water onto the soiled surface.
