Pop your item in the washing machine – we recommend placing any silk items inside a mesh laundry bag or pillowcase to avoid snags or damage caused by the drum. Select a cool, delicate cycle (do not set the wash temperature to any higher than 30°C).
The safest way to wash delicate silk garments at home is to hand wash them. If the fabric care label tells you to “Dry Clean” or not machine wash, then it's best to wash by hand.
Believe it or not, the washing machine is an option for silk (more on that below), but Yokoji cautions that it's not the best way to go as it can lead to snags and tears in the delicate fabric. Instead, she recommends handwashing as the safest route to care for any clothing or bedding made of silk.
For many years, it was thought that dry cleaning was the only way to properly care for silk – but silk can actually be washed at home. While the care labels on many silk products may instruct that the item be dry cleaned, this is simply down to the manufacturers preference.
Hand Wash
While you can toss your silk pieces in a gentle wash cycle, Whitehurst says it's best to wash these velvety soft items one at a time in the sink. Fill your basin with cool or cold water to help keep the color, then add a gentle detergent that's free of harsh ingredients.
So when you see a delicate or 'dry clean only' garment made with wool, silk, cotton or cashmere, you can wash them at home so long as you perform a test on the garment first to ensure there's no color bleeding, shrinkage, warping, or other naughty garment behaviour.
Don't put silk items in the dryer. Heat can damage delicate silk fibers. If the dryer is absolutely necessary to use only 'air' setting for 15 minutes or less with NO fabric sheets or dryer balls. Remove sheets before completely dry.
Too much or the wrong detergent can make silk rough. Be sure to use a non-alkaline detergent. Adding ¼ cup of vinegar to the first rinse helps to work as a natural fabric softener.
All Woolite® products are liquid detergents and are specially formulated for the machine to not cause shrinking, stretching, or fading on washable suede, linen, cotton, washable wool, silk, rayon, polyester, cotton/polyester, nylon, nylon/spandex and rayon/spandex.
To restore some of the shine and softness that's been lost, you can give your silk pieces a mild white vinegar bath. White vinegar helps to remove any residual soap in the fibres, and also restores lustre and softness to silk.
If you find that the sheen of your silk clothing has lost its luster or shimmer and appears to have a white film or looks dull, the silk fibers may have become damaged due to improper cleaning or exposure to too much light or heat.
Silk reacts to alkaline detergents. These can cause the silk to become rough and even cause the fabric to break down. So, when washing silk, even by hand, ensure that you use a mild detergent. Some people even make their own detergents just for silk.
Wash silk after every few wearings unless it needs freshening and stain removal. Remember that washing your silk clothes at home may put the garments at risk of color fading if cleaned too often. Dry cleaning usually doesn't fade the color of silk clothing as fast as home washing.
Rinse with cold running water. You may want to soften the shirt by soaking it in water and white vinegar (1/2 glass per 2 litres/67.6Oz of cold water) for 10 minutes and rinse it with cold running water.
Silk. While silk is a very luxurious material, it is also very delicate and can easily shrink or become damaged in the wash without proper care. Because silk is a natural material made from protein fibers, heat will cause it to shrink.
If you do not have a steamer, try hanging your silk in the bathroom while you take a hot shower. The steam emitted from the hot shower water can help to straighten your silk fabric. This is: How to Get Wrinkles Out of Silk Without an Iron.
Activewear, loosely woven garments, silk, and items embellished with beads or embroidery are best dried on the delicate or gentle cycle. The low heat helps keep your clothes safe during the drying process, as these garments are prone to melting or stretching under high heat.
Whichever washing method you choose, remember that a gentle but effective liquid toxin-free laundry detergent is the best detergent for silk pillowcases (and for your health!) Avoid harsh liquid and powdered detergents, as these products coat and weaken the natural fibers.
This one's true - we would never recommend tumble drying silk, because heat can cause silk shrinkage. If you tumble dry your silk pillowcase, you could well find out later on that it will no longer fit over your pillow.
If you're still dubious, you can always hand-wash your silk, using lukewarm water and a mild detergent. A good alternative is a non alkaline soap or even baby shampoo!
