Is Thankyou Universal Cleaner septic tank safe?

Our Universal Cleaner is a 100% Natural hospital-grade disinfectant. As we have not conducted the specific testing of our Universal Cleaner within a septic tank system, we recommend adhering to guidelines from your septic tank provider/council/state on products to use with septic tanks safely. Typically, disinfectants are included in the list of products to avoid pouring undiluted into a septic tank. Like the other products listed, disinfectants will kill (some of) the beneficial bacteria that make the septic work properly.
