The last alternative technique to defrost the refrigerator in a less tiring and faster way involves the use of denatured alcohol. How to do it? Use a cloth to dip in warm water, then dampen it with denatured alcohol. Once in contact with the ice, the latter will melt quickly. This method works effectively when the layer of ice to be removed is thin, so it is not recommended to apply it to melt very thick blocks of ice.
