Metal kettles will benefit from a clean with soapy water then a lovely buff with a microfibre cloth to banish streaks.

Descale a kettle by filling it with half water and half clear vinegar. Leave overnight, empty, wipe out, refill with water, reboil, empty, refill, reboil, make tea.

Plastic kettles should only need a wipe down with warm soapy water – don’t use anything abrasive or it will scratch the surface. Discoloured marks may improve after rubbing them with a cut lemon or professional claning products.
