Abstract
A detergent composition particularly useful in aqueous solutions for cleaning soiled surfaces. The formulation which may be in either dry or concentrate form, includes alkaline builders, wetting agents, and a flocculant, and may in certain instances, include a floatation agent. As an alkaline builder, sodium tripolyphosphate is normally preferred, while others such as mixtures of sodium tripolyphosphate with sodium sulphate or potassium hydroxide and soda ash may also be successfully utilized. The formulation is preferably applied to the surface as an aqueous solution in relatively heavy or thick layers, with agitation to permit the removed soilage to create flocs, and with the flocculated soilage being floated away from contact with the surface for facilitating removal.
