Washing machines are a godsend in homes up and down the country, but they're becoming increasingly expensive to run.
Nasty smells in your washing machine are caused by mould and bacteria. When you put clothes in your machine, body oil, dirt, hair, and other scum gets trapped in the gasket, seal, and detergent dispenser.
If your washing machine smells bad, this can then lead to clothes smelling like damp - even when they've been washed and dried.
