Unsurprisingly, shower heads are very vulnerable to mould and mildew because they are constantly being exposed to moisture.
It's common that black, green or grey specks will start to appear, particularly on the holes where the water comes out.
Luckily, fans of the cleaning guru Mrs Hinch, whose real name is Sophie Hinchliffe, have shared an overnight trick that can be used to remove the pesky build-up of mould.
Mrs Hinch rose to fame after posting cleaning tips and recommendations online, and now she has an army of fans who share their own tricks and hacks online.
Posting on the Mrs Hinch Cleaning Tips Facebook page, one woman asked for advice on "how to clean a shower head". She added: "Mine has gone black in the holes where the water comes out. I've tried bleach but it didn't work."
The post gained almost 100 comments, with many people sharing the same hack to get rid of the pesky grime.
Many agreed that the best trick is to soak it overnight in a solution of bicarbonate of soda and white vinegar.
One person suggested: "Fill a food bag with bicarbonate of soda and white vinegar and put the shower head in and tie it for 2 hrs should come out lovely."
Another said the same, adding: "Take showered off, put in a food tie bag with an solution of bicarb and white vinegar and leave overnight. If needed then use an old toothbrush. Works every time."
If you don't have bicarbonate of soda, one savvy cleaner suggested using lemon juice instead.
She said: "Take the shower head off. Clean the little holes with a toothpick then place the head in a large sandwich bag with a white vinegar and lemon juice mix. Leave for half an hour or so then rinse and scrub."
Others suggested specific products that could help remove the mould, such as Astonish Mould & Mildew spray, and Viakal.
Another Mrs Hinch fan said she always puts hers in the dishwasher, which works a treat.
