Properties of chlorine cleaners
You can buy special chlorine-based drain cleaners in shops. These chlorine cleaners are usually used for disinfecting. Most of us are familiar with chlorine as a disinfectant commonly added to swimming pool water. Its sodium hypochlorite content is highly effective for cleaning drains and usually dissolves blockages very quickly. However, chlorine is very aggressive and can irritate skin and airways. Chlorine is also harmful for the environment and should only be used sparingly. In many cases, there is no need to use chlorine to clean drains and gentler everyday household products will do the job just as well.

Using chlorine to clean pipes
Take care when using a chlorine cleaning product: Wear protective clothing if possible, such as gloves, a face mask and safety glasses, and avoid inhaling the very caustic fumes.Open the window and make sure there is sufficient ventilation. After cleaning the drain, rinse it thoroughly with clean water. Make sure there is no chlorine residue in the washbasin or shower tray. The aggressive alkaline content of the chlorine cleaner can attack surfaces and damage your washbasin, shower tray or bath.
Where possible, choose organic enzyme-based drain cleaners rather than chlorine.They take a little longer to work, but are gentler and less harmful for the environment.
