METHOD FOR CLEANING ENVIRONMENTAL SOILS FROM OUTDOOR UNFINISHED SURFACE

摘要

A method of diluting concentrated cleaning composition and cleaning outdoorsoiled surfaces with the diluted cleaning composition. The concentrated cleaningsolution can include an aqueous chlorinated bleach solution, a surfactant, a phosphateand a silicate. The concentrated cleaning solution is diluted with water to form adiluted composition which is applied to the surfaces to be cleaned to effect looseningof soil. Thereafter, the loosened soil is removed by the mechanical action of a waterspray. The cleaning composition can be sprayed onto the surface to be cleaned by ahand held sprayer such as an air-gap or closed venturi type of hose end sprayer.
