Let the Worm Do the Work: Earthworm products use a naturally-occurring process to break down organic materials. All living things contain enzymes. Our bodies use about 75,000 of them to help perform tasks like breathing and digesting. We've harnessed these enzymes to break down food, grease and almost any other organic material. Enzymes act as a biological catalyst to increase the rate organic material is broken down. Instead of plunging, the natural bioenzymatic process does most of the work, which is why we say, let the worm do the work. And when the task is completed, no harsh chemical residues are left behind. Earthworm Drain Cleaner is ideally suited to clean almost every type of drain and will also control their odors. Regular use of Earthworm will prevent clogs before they start by eliminating the build-up of organic material in your drain lines. Earthworm can be used in kitchen and bathroom sink drains, floor drains, bathtub and shower drains, as well as boat and RV holding tanks and grease traps. Unlike those drain cleaners with harmful caustic chemicals, Earthworm is safer for use in garbage disposals and will keep smelling fresh. For septic systems and cesspools, try Earthworm Septic System & Cesspool Treatment (powder or liquid). All Earthworm products are environmentally responsible and safer around kids, pets & family.
