ABSTRACT:
A stain remover composition and method of use which selectively reduces food and beverage dyes in carpet stains without causing fading or discoloration of carpet dyes present in carpet fibers. The stain remover composition comprises generally between approximately 0.1 weight percent and approximately 2 weight percent of alkali metal silicate, between approximately 4 weight percent and approximately 12 weight percent of water soluble alcohol, between approximately 1 weight percent and approximately 5 weight percent of sequestering agent, between approximately 0.1 weight percent and approximately 2 weight percent of surfactant, between approximately 4 weight percent and approximately 12 weight percent of sodium bisulfite or other mild reducing agent, and the remainder water. The stain remover composition is generally prepared and stored as two separate solutions, with one solution containing the reducing agent and the other solution containing the remaining ingredients. The two solutions are mixed together prior to use, and then applied to a carpet stain, followed by steam heating of the treated carpet stain and water extraction of the treated stain.
