ABSTRACT:
A concentrate for producing a reactive mixture which mold and mildew cannot tolerate and which removes mold and mildew from a surface without scrubbing. The primary active ingredients of the concentrate consist essentially of acetic acid, sodium metasilicate, sodium tripolyphosphate, sodium alkyl benzene sulfonate, and sodium-o-phenylphenolate. A surfactant such as polyethoxylated nonyl phenol can be included to increase the solubility of the phenolate in aqueous solution.
An improved method of preparing the concentrate in a manner to prevent formation of silica gel includes adding the acetic acid last, and a three stage mixing procedure. The mold and mildew is removed by mixing the concentrate with water and bleach, and thereafter spraying the mixture onto an area to be treated.
