Edwin Stipe, Inc. also recommends using Bio-Clean for regular maintenance of your pipes. BIO-CLEAN is a non-poisonous, all-natural blend of bacteria and enzymes that attacks grease, hair, food particles, paper, cotton & sewage. This makes BIO-CLEAN safe for people, plumbing and the environment. BIO-CLEAN changes the waste particles into water, carbon dioxide and mineral ash which run harmlessly out of your waste system.
