It’s important to clean your kettle every few months. Limescale and other mineral deposits build up inside your kettle over time and this will affect its performance, or even shorten its lifespan, so you’d be wise to pay it some attention occasionally. Not to mention, the cream-colored tartar looks super gross, god forbid a family member should take a peek inside your kettle if they've helped themselves to make coffee without a coffee maker.
"Understanding what your water hardness type is and how often you should descale your product, will massively improve the taste of your hot drinks and lengthen the lifespan of your appliance," says Debbie McIvor-Main, marketing manager at Dualit Ltd. "If you live in a soft water area, we recommend you descale your kettle every two months or every 100 cycles. If you live in a medium water area we recommend you descale your kettle once a month or every 50 cycles. And, if you live in a hard water area we recommend you descale your kettle at least once a month or every 25 cycles."
