The main components of scale are calcium carbonate and magnesium hydroxide. Long term accumulation can lead to a decrease in heating efficiency by more than 30% and may also breed bacteria. The correct cleaning method should be selected according to the thickness of the scale: mild scale (thickness<1mm) can be boiled in white vinegar (1:10 ratio with water) and left to stand for 30 minutes, then brushed with a sponge; Severe scale can be treated with food grade citric acid. After heating to 80 ° C and soaking for 2 hours, its chelating effect can quickly decompose the scale without residue. There are two major misconceptions to avoid: first, do not use steel wire balls to scrub, as it may scratch the coating of the inner liner and cause metal leaching; The second is to avoid using industrial descaling agents, whose chemical components may remain and contaminate water quality. In terms of prevention, it is recommended to empty the pot after boiling water each time. In areas with hard water, a front water purifier can be installed, or mild descaling maintenance can be carried out once a week.
