Hi
I’ve had my electric kettle for a couple of years now. I was told adding lemon juice or a product called “McKenzie’s Citric Acid” (dehydrated lemon powder) to the water and boiling it would be good for cleaning out the kettle. The lemon powder does seem to work but I still get a bit of a stain left behind in the bottom of the kettle. It’s one of those metallic kettles with a hidden element at the bottom.
A friend of mine uses caustic soda. I haven’t tried that yet. Would that be safe even after you rinse it out?
What do other people use?
Thanks
