A carpet cleaning composition comprises a terpene hydrocarbon solvent that
also functions as a fragrance, one or more surfactants, an anti-soil
component, an anti-stain component, water, and, optionally, an anti-foam
agent and a pH adjusting agent. In the preferred embodiment, the terpene
hydrocarbon solvent is d-limonene, an organic, low volatility solvent
produced from citrus oil extract. The pH adjusting agent maintains a pH
in the carpet cleaning composition between 8.5 and 9.5 and preferably
about 9.0.
