Soil and grease which has been allowed to remain on the skins for an extended period of time becomes “oxidized” and may be permanent. More aggressive cleaning methods are required which may affect the color or damage the skins. Also, certain stains will cause permanent damage if allowed to remain on the skins. Salt and protein stains can cause skins to shrivel, hardened and crystallize (called a “burn” in the industry). Salt used as an ice melter is a common occurrence on hemlines, footwear and gloves. Other substances that will cause permanent damage are blood, urine, milk products and alcohol (beverages, hairspray, perfume, etc.).
We recommend sending your leathers and suedes to a Professional Leather Cleaner at the end of every season or whenever exposed to dangerous stains.
