From time to time you may notice stains or discolouration in the areas where you use water, e.g. around taps in sinks and basins. In nearly all cases this is not caused by the water itself. However, we can offer some easy solutions to help you resolve this problem.
Pink or red stains
The reddish-pink colour sometimes seen on shower curtains, bath sealant or around taps is not caused by the water itself but by the growth of common bacteria or yeasts. Both can thrive in moist, warm environments like those found in the bathroom. These bacteria or yeasts are naturally occurring and can be present on surfaces or air-borne, and their presence does not indicate a problem with the quality of the mains water supply.
Black, grey or reddish staining
This type of staining can occur around taps in the bathroom or showers, on the grout between tiles and in your washing machine powder drawer. The staining is caused by the presence of air-borne mould that can grow and spread in damp areas. The problem can be made worse if the area is poorly ventilated or if aerosol deodorants or other sprays are used. The aerosol droplets can provide a food source for the mould.
What can I do?
The best solution to both problems is to regularly wipe down wet surfaces and increase air circulation by opening a window or fitting an extractor fan to ensure that affected areas are quickly dried out after use.
Household cleaners, disinfectant or bleach solution can be used to kill off the bacteria or yeast spores and clean off staining. There are also specific cleaners designed to tackle mould. Always ensure you read the instructions on any products you use. It can sometimes be more beneficial in preventing regrowth if household cleaners that do not have fragrances are used, as sometimes the fragrances can encourage more growth.
