Cocoa stains can be tricky because of their protein and fat content, so quick action is key.

First, rinse the stained area under cold water to stop it from setting into the fabric. Next, apply some liquid laundry detergent or a mild, grease-cutting washing-up liquid and leave it to work for 10–15 minutes.

If the stain is still visible, soak the garment in lukewarm water with either a little baking soda or an oxygen-based stain remover. Then wash the garment as usual at the temperature recommended for the fabric.

For white fabrics, a splash of lemon juice or a little hydrogen peroxide can also help lighten the stain – but always test on a hidden area first.
