Microwave a cup with water and vinegar until it boils. Then a single wipe cleans everything
You do this every time you use your microwave? Because we’re talking about making around 6 - 10 cups of tea every day for everyone who happens to be in the room. It’d be a little odd to go and clean your microwave before every round of tea, not to mention microwaves don’t heat things evenly so you can’t do them all at once, it very quickly becomes way more effort than just flipping the switch on a kettle that is only ever used for that purpose.
who has time to wash the benches either ? why bother oneself with vacuuming the floors ?
