From time to time, you may notice stains or discolouration in the areas where you use water, such as around taps in sinks and basins. In nearly all cases, this isn't caused by the water itself.
But why does it happen?
Pink or red stains can sometimes be seen on shower curtains, bath sealant or around taps. This isn't caused by the water itself, but by the growth of common bacteria or yeast. These are completely natural, and don't affect the quality of your mains water supply.
Black, grey, or reddish staining can occur around taps in your bathroom, on grout between tiles, and in your washing machine powder drawer. This is caused by airborne mould that can grow and spread in damp areas. If the area is poorly ventilated, then this problem can become worse.
Fixing it
Regularly wipe down wet surfaces and increase air flow within your property by opening a window or fitting an extractor fan.
TOP TIP: Household cleaners, disinfectants, or bleach can be used to clean off bacteria or yeast spores and staining. There are also specific cleaners that are designed to tackle mould. Always ensure you read the instructions for any product you use.
