Off The Shelf Commercial Spot Removers
According to a study sponsored by the Carpet and Rug Institute, an independent laboratory tested off-the-shelf spot removers and pre-spray solutions. 25 products were tested but ONLY 4 cleaned a soiled carpet sample better than water. Some caused the cleaned carpet area to re-soil faster, and some products even damaged the carpet’s color and texture.
In short, it’s better to contact a professional than to use off-the-shelf products to remove spots and stains from your carpet.
