Do you clean your kettle inside? Do you replace the water often. Is there a cert!

Do you clean your kettle inside? Do you replace the water often. Is there a certain kettle etiquette?

Someone asked a question about boiling a kettle without water in it and it tweeked my brain strings heh.

I've always thought it's gross that the water in kettle could sit there for days, and that it never gets cleaned inside (well we don't clean the inside of ours)

Do you clean inside your kettle? Because the waters boiled everytime, does it make the water become clean??

Has anyone else ever thought about this?

ewww I change mine and wash it everytime I use it.

I didnt know people let it sit there for days...eeekkk lol
