Ok don't no if I'm in the right place but I thought to add this, is your kettle got water stains inside and you want it cleaned well this works for me!! It removes that built up scale on the bottom steel plate where the element heats and helps it boil better. 1/2 cup white Vinegar and 2 whole lemons squeezed. Let it sit for 5min then boil but not all the way as it will flow out, once you see it start to rise stop it, then just use a bottle brush and scrub till shinny. Rinse it out a few time then add half water boil it then drain. Now your Kettle will operate as new.
