The electric kettle has been used for a month. Is it rusty?
Boiled with mineral water, do not use hard objects, no clean-up scale, and destroyed the stainless steel surface more easily rust.
Solution: 1, put the lemon peel, cook a little bit, and then a little later on the line. 2, warm water, put white vinegar, square side will do. 3, buy a household water processor to filter the water quality.
Each region is not the same water quality, depending on your situation, you water quality is hard.
