What is the frost on the shoes?

The frost on the shoes is pantothenic nitrate. Wipe the pan-nitrate stain with clean cotton cloth and a small amount of white vinegar to remove it.

In our daily work, we often encounter the phenomenon of white vamp, which is called pan-nitrate. Most of them are caused by wearing them in rainy days. To solve the problem of pantothenic nitrate, be careful not to touch acid, alkali and oil. Always polish the shoe polish and wipe it with gauze dipped in a little warm water.

To solve the problem of pan-nitrate, be careful not to touch acid, alkali and oil, otherwise it will easily cause the deformation of leather shoes. Leather shoes with cowhide soles should not be in contact with water, otherwise it is easy to cause delamination, degumming and deformation of soles.

Never wear leather shoes in rainy days, and never scrub the dirt on the upper with water on weekdays. In particular, consumers must not expose soaked leather shoes to the sun or bake them with fire intentionally or unintentionally. Otherwise, it is easy to cause flooding, skin fracture, deformation, degumming, decoloration and other adverse consequences.

Leather shoes should be polished frequently, so that the leather surface can be kept bright, but leather shoes should not be polished too bright. If you find that there is hoarfrost on leather shoes, you can wipe the hoarfrost on the surface with gauze dipped in a small amount of warm water, put it in a ventilated place to dry, and then apply shoe polish evenly.
