To remove dents from stainless steel, a dent puller kit can be used or the heat and cold method can be tried. First, heat the dented area with a hairdryer for several minutes to expand the metal [1]. Next, quickly apply a can of compressed air held upside down to the area, spraying it to rapidly cool and contract the metal. This sudden temperature change may cause the dent to pop out. For larger dents, a plunger or a vacuum cleaner with a suction attachment can also be effective [2].
