Abstract
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.
