Some of the fillings used in the older bears were never designed to be washed, so never put your bear in the washer! Apart from it being traumatic for the owner watching the little thing spin, your antique teddy bear will probably come out in bits!
If your bear is really valuable, seek professional help and do not attempt cleaning it on your own. Professionals are insured (check first though) but you are not. If you must attempt to clean your bear do make sure it is in excellent condition first and wear cotton gloves to prevent the transfer of natural oils from your hands. Use a little luke-warm water with some very mild liquid detergent that is specially designed for fragile fabrics and swish it up. Dip a sponge or very soft cloth into the foam only and gently stroke the fur. Do not make the fur wet! Dab off any wetness with a dry soft cloth, but do not rub the material.
Leave your antique teddy bear in a warm and natural atmosphere to dry completely on his own. Then fluff up the fur gently with a soft brush.
There are not that many around, but a really useful book to read that is full of excellent tips and information about cleaning and restoring your antique teddy bear can be found HERE.
