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.
