H1 PLUS IS A NON ACIDIC ALKALINE BASE TOILET CLEANER. It is a toilet cleaner that cleans the surface without burning it. While other toilet cleaners clean the surface by burning it. Continuous use of acid-base toilet cleaners can cause the surface to become rough, leading to yellowing and scaling in the surface. As a result, bacteria quickly begin to form on that surface, which can cause fatal diseases. H1 PLUS is a toilet cleaner that removes dirt from the surface without any damage and keeps bacteria away from the surface for a long time. Also keeps the environment free from odor.
