i only use my kettle a few times a week, but usually there is some water left in there from the last time.
how many days can you leave boiled water in a kettle, and then still use it?
i know it wont kill me etc, i mean when does it lose its quality or taste weird etc
when is it no longer ok to reboil it and use it?
i know tapwater in a glass at room temp starts to go weird tasting after about a day, & about 4 days, it can start to yellow
but the water in the kettle has been boiled immediately from the tap.
If you only boil as much water as you are going to use (2 cups of tea - put 2 cups of water in the kettle) you will save electric, save water, and not have the dilemma of leaving water in the kettle for days!
