When a fur coat needs cleaning, it is essential that you take your garment to a fur specialist, not a dry cleaner. Fur requires a very special cleaning process that most dry cleaners cannot do.
Even if there is no visible dirt or stains, fur should be cleaned at least once a year. Cleaning can remove dirt particles and chemicals, and involves a glazing procedure that improves the lustre of the fur.
This might seem like a lot of effort, particularly if the coat does not appear dirty, but keep in mind that the coat will last much longer if cared for properly.
