Bicarbonate of soda – this is great for getting rid of smells, and it’ll also brighten your clothes. If a load of laundry smells particularly bad, throw about 90g of bicarbonate in with your clothes, then add detergent as usual. Your clothes should come out smelling a lot fresher. If the smell is really stubborn, you can soak the clothes beforehand.
Vinegar – you can use vinegar in much the same way as bicarb. Put it in the washing machine with your detergent, or soak your smelly clothes overnight in a mixture of three parts water to one part vinegar before washing.
Remember: never mix vinegar and bleach. They can react to create chlorine gas, which is toxic.
