Our friends from Fur Hat World have this excellent guide on how to maintain our fur stuff:
Unless you have a very delicate fur like chinchilla, your fur hat is a fairly durable item and simply must be treated with common sense. Furs like cold, hate heat. They don’t like friction, or chemicals. They like space, and to be cleaned. – but, only by a fur professional.
Give it a good home. Be sure to store your hat in a closet that is not exposed to light (which will fade your fur) or heat. Make sure it has room to breathe and is not crushed by other garments.
Avoid insecticides, mothproofing, and other chemicals around on your fur, including perfume, hairspray and makeup. Perfume contains alcohol, which can dry your pelts. Once a perfume gets into your fur-including cedar from a cedar chest- it will be there to stay.
If your fur gets wet, don’t panic. Most furs can handle snow and a light rain with ease. Shake it out and hang it to dry in a well ventilated room. Please resist the temptation to speed the drying process with a hairdryer or near a heat source. Remember furs do not like heat. After it dries you can then shake it again. Comb or brush it gently if the hairs seem a little bristly. If your fur has been soaked thru, however, take it immediately to your fur retailer for proper treatment.
In the off season it doesnt hurt to send your fur hat to your local furrier for professional storage. This is optional but will ensure your hat stays in good condition through the warm months.
If your fur hat gets dirty have it cleaned by a professional fur cleaner. Besides just cleaning, this conditions your fur. Glazing is a process that replenishes oils to maintain a furs longevity. You may consider taking your hat to a furrier for glazing if you find that it needs to be refreshed.
Suede and leather can be hard to clean. It is advised that you have suede cleaned professionally. However there are a few steps you can take if the light soil is not too bad:Rub suede with a clean dry towel – always rub suede in one direction.Remove the stains or marks by gently rubbing them with a pencil eraser.Brush your suede with a suede brush, which has soft bristles with wire inserts (most stores sell this in the shoe area for suede shoes).
