2. Heating method

Soak the towel in boiling water for a few minutes before washing, and then wash it while it is hot, which can also effectively remove the scale on the towel, because the scale will dissolve after heating, but it will still condense together if it is not removed in time, so be sure to wash the scale off the towel while it is hot.
