The white spot treatment on the surface of safety shoes after wearing for a long time. The leather safety upper leather has a strong ability to absorb sweat. Therefore, after wearing safety shoes for a long time, some white sweat spots will appear on the leather surface. This is the exudation of the salt in the sweat absorbed by the leather and the substances contained in the leather, which is called salting out. Especially in rainy weather, when safety shoes are damp and dried, this kind of white spots are often precipitated.
