Deodorant stains – especially those from antiperspirants containing aluminium salts – can leave stubborn marks on clothing.

To tackle them, make a paste using bicarbonate of soda and water, gently rub it into the stain, and leave it to sit for around 30 minutes. Then rinse thoroughly and wash the garment as usual.

Alternatively, you can soak the item in a mixture of vinegar and water – this helps to break down the build-up and lift the stain.

Oxygen-based bleaches can also work well on white fabrics, but always check the care label and do a patch test on a hidden area first, just to be safe.
