As it's where we cook and eat our food, we tend to avoid thinking about just how dirty our kitchens can get.
But a new study shows one appliance in particular gets the dirtiest - and we use it a lot. You guessed it, it's the trusty microwave.
Whether it's defrosting meat, softening butter, or heating up leftover soup, all kinds of smells and stains get left in this appliance, and it could do with a clean a lot more often.
UK cookware store Oliver's Kitchen carried out research revealing that 80 per cent of people admit they never clean their microwaves, according to Metro UK - which is disgusting when you consider how often food can spill over or spit as it heats up.
