We had a blood stain in the middle of our living room and Chuck cleaned it beautifully. No residual or any hint of a stain and the carpet looks brand new. He treated a few older stains which also came completely clean.
We use them to routinely clean our carpets and are very pleased with the safety of their products for our pets and the great results of the cleaning. We highly recommend them.
