If your faux fur has become flat and matted, there are a few things you can do to make it fluffy again. First, try brushing the fur with a soft brush or comb. This will help loosen any dirt or debris that may be stuck in the fur. If this doesn't work, you can try lightly misting the fur with water and then brushing it out again. Finally, if all else fails, you can try taking your faux fur item to a professional cleaner for a deep cleaning.
