Shoe care refers to a series of care work such as cleaning, sterilizing, maintaining, glazing, polishing, complementary color and mildewproofing of leather shoes, so as to restore the beautiful appearance of beautiful shoes and prolong the service life of leather shoes. The pH of the detergent and care agent used should be between 5 and 7.5.
