All sheepskin garments with a 'leather look' have a sprayed on finish. This is true of every brand available on the market, and the finish will wear to a suede-like appearance over time. This finish is colourfast under normal circumstances.
However, certain solvents on hands or surfaces can slightly damage the dark brown finish in a way that the colour could run. These solvents include: Leather seat treatments, hand creams, perfumes, petrol, oils, etc. Seat belts can also 'rub' the surface causing a mark, over time.
Do not dry clean, you will need to find a specialist sheepskin cleaner to clean your item. For small areas and patch cleaning, use a very dilute baby shampoo sparingly over the 'wool' area and allow to dry naturally. Once dry you can carefully tease out the wool with a pet comb (do not touch the 'leather-like' surface as this will scratch). For the outer surface of the jacket use a wax based leather food very sparingly and gently wipe over.
Do not use a chemical/solvent leather cleaner or saddle soap as the outer surface is NOT leather.
Store out of direct sunlight and away from a heat source.
Do not store in polythene, a small, old cotton duvet cover or similar is ideal.
