Fur coats need proper cleaning. Fur material has natural oils in the pelts that will dry out if not cleaned. If this happens, the hides become so fragile or weak that they will tear with unbelievable ease, making the garment useless. If you feel a fur and then rub your fingers, you should feel a very light oiliness.
Pollutants, dust, and airborne particulates are drawn to this and get caught in the fur's hairs. They then act like a sponge drawing the natural oils out of the pelts. These particles also have a harsh effect on the fur's hair that can exhaust the natural shine of the fur over time, causing it to look shabby and worn. When you clean a fur, your main goal is to eliminate these materials from the hairs. For this reason, its crucial to have your fur cleaned by an expert.
