| Purinel
Purinel is a strong, acid-based cleaner that is designed to sanitize and clean surfaces, kill germs, attack hard water deposits and prevent scale and stains from forming.
Although it is an acid-based formulation, it is safe to use and kind to pipework.
Purinel is extremely effective in killing a broad spectrum of bacteria very quickly. In the first flush it will remove up to 99.3% of germs and bacteria that are lying on the surface and produces a thick foam that dissipates slowly after every flush. |
