To get the most from your Castanea cashmere regular cleaning is required. It is important to give them a thorough cleanse & avoid having a sleeping pile of knitted sweaters in your laundry room! Unfortunately there are harsh consequences to washing your cashmere incorrectly; so please follow this guide carefully. Cashmere does fall into the hand wash & dry clean only category. It can be washed in a laundry bag if your machine has a cold hand wash cycle but they will last much longer if washed by hand.

Step 1.

It is best to use a clean sink or basin, make sure there is no residue of cleaning products on the surface of whatever you choose. Fill the basin with cool to tepid water. It is not necessary to freeze your hand off with polar ice cold water! Add a small amount of gentle cashmere or knitwear detergent. We recommend the Laundress cashmere shampoo, Ecover delicate, or you can use Woolite. Briskly swirl the shampoo in the water with your hand for even distribution & to generate suds.

Step 2.

Turn your knit inside out and submerge in the water. Make sure to not mix any colours together.

Gently massage the soapy water through each fiber. Don’t rub, wring or twist the fabric while washing. Spot treat any problem areas with a squirt of neat detergent and massage gently with fingertips. Allow the garment to soak for 5 – 10 mins. It might be good to set a timer at this point as you may walk off and forget!

Step 3.

Drain the bowl or sink and rinse until the water runs clear. Be sure to use the same temperature water as you used to wash. Don’t wring or twist to remove excess water, instead lay the item out on a towel, gently roll up (like a sausage roll) and lightly press. Remove the sweater from the towel and reshape by hand. Lay the cashmere on a dry clean towel and let it air dry.

Button up cardigans and pull pockets straight. Keep it away from heat sources like radiators and sunlight, allowing it to air-dry naturally.

Step 4.

Once dry, fold your cashmere carefully. You can give it a gentle steam to remove any creases. Do not lay an iron flat on your cashmere. If you can, we recommend you wrap your cashmere in acid-free tissue paper, which preserves original colour and protects against damp and dust. Store your clothes in a well-aired area, dust free and covered, away from sunlight.


Moths love cashmere and they are particularly attracted to the natural oils we produce when wearing our cashmere. They love our dirty clothes so to keep the dreaded moths away we recommend hand washing your sweaters regularly. Also lining your chosen storage area with fragranced anti-moth paper. If it’s a wardrobe, invest in some cedar balls or scented sachets.


Cashmere is a fine fiber and pilling will happen depending on the amount of wear and tear you give it. This is not symptomatic of inferior quality, but rather an inevitable consequence of the careful processing of this fine fibre. Avoid any rubbing motions with your handbag & purses. Also try to keep your knits away from jewelry as it can cause snags.

Pilling can easily be removed using de-bobbling comb or even a standard razor, though you need to be very careful not to cut the fabric if doing so.

Your Castanea cashmere will improve with age if cared for properly, and will last for years to come.
