The Carpet and Rug Institute (CRI) has launched a new Seal of Approval program designed to recognize carpet cleaning products that pass stringent tests administered by an independent, accredited laboratory. Since August, three products have been awarded the Seal of Approval. Companies seeking the distinction must pass a series of tests administered by Professional Testing Laboratory Inc. of Dalton, Ga. Testing covers spot removers and pre-spray/in-tank solutions, which may be used in residential, commercial or institutional settings.

The testing program's parameters include efficacy, resoiling, pH, optical brighteners, and colorfastness to light. Products that have passed the testing criteria for the cleaning products will be listed on the CRI website: www.carpet-rug.org.
