Went to my sister in laws for a coffee this morning and she asked to me fill the kettle while she was sorting the dog. I took the lid off to put under the tap and noticed how black and scaly the bottom of the kettle was, like it had never been descaled.
I had a coffee but definitely didn’t enjoy it after seeing the state of the kettle! Do you descale your kettles or is it normal for residue to build up and just live there for the duration of the kettles life?
