Abstract
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.
