The explosions are caused by super heated water seeping into the hollow spaces of the tea kettle. Yes, you can heat milk in your kettle as well! Just empty your kettle of water, if there is any in there, and add your desired amount of milk. The only difference with heating milk in your kettle rather than water is you will have to pay more attention to it. Most would advise you to avoid letting the milk boil. Soak your kettle for anywhere between 20 minutes and two hours, depending on the degree of the burn.
Limescale comes from the high concentration of calcium found in the hard water we drink, so it will not cause you harm if you consume some from your kettle or coffee maker. Discard the water and vinegar after use.
This causes the disk to snap and disconnects the power. Boiling the water kills microorganisms such as viruses, bacteria and parasites. When using a microwave oven, ensure that the water boils hard. You can store treated water in well-sealed containers for 6 months. The resulting precipitate of calcium carbonate is called "temporary hardness" because, as you have observed, it is easy to remove with any mild acid.
Some other forms of scaling are much less forgiving. Now, if your water hardness problem is severe, a lot of carbonate will start to precipitate as soon as the kettle is heating up. This is why another commentator suggested that it is too late to do anything after the kettle has boiled: that the scale deposits have already grown. However, there are two complications.
Firstly, the supersaturated calcium carbonate solution doesn't necessarily all precipitate at once; the scale crystals may continue to grow for some time. I can't say just how long, but a process whereby large, hard crystals tend to cannibalise small, soft ones can continue for weeks. Secondly, you will not see hardness that bad from mnay common water sources.
Well water, maybe, but most municipal supplies will already be softened to the greatest degree that it is economical. If the water hardness problem is mild, some of the calcium carbonate will precipitate immediately, but some more than 6. Long story short, your boss's concerns are not unreasonable. On the other hand, as you note, temporary hardness is easily cleaned off, and only temporary hardness is related to boiling.
On the third hand, it's his kettle and he's the boss, so do as you're told! Sign up to join this community. The best answers are voted up and rise to the top.
