Despite what you've heard, you can wash silk in a washing machine. However, it's worth investing in a mesh bag to protect your delicate items from tangling or getting caught on other items during the wash. Follow the instructions for washing silk items in a washing machine.
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).
You can use shampoo, a dash of vinegar and water. This creates an excellent solution to wash silk in and pretty much eliminates stiffness after washing.
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.
Don't forget that silk loses much of its strength when it's wet and wringing it out will damage it. Lay out each wet piece on a clean, dry towel and roll it up. The excess water will soak into the towel. To finish drying, lay the garment flat.
Softening Rough Silk After Washing
Air drying can make silk a bit crispy. Use these tips to soften it up. Gently run an iron over it on the "silk" setting while still slightly damp to soften it up.
Using too much detergent can leave residue on the fibers, making them feel rough and stiff. This is because detergents can strip the natural oils from the silk, which help to keep the fibers soft and smooth. To avoid this, use a gentle detergent and follow the recommended amount for the size of your load.
Silk is a delicate fabric easily damaged by heat and agitation. If you're going to iron your silk clothing, start by testing the fabric for heat tolerance.
Silk is a delicate fabric, and you'll want to make sure it stays beautiful even after you've cleaned it. Washing it at too high a heat can cause it to shrink and damage it. It may be worth getting your silk garment professionally dry cleaned to avoid damage if it's particularly precious to you.
Sun and Water Damage. Silk is highly susceptible to damage from the elements. Even a tiny bit of water can leave a visible stain that's impossible to get rid of. And sunlight weakens the fibers of silk, resulting in tearing and fading.
It is easily stained, even when splashed with plain water, and those stains can be tricky to get out. Improper or overly aggressive stain removal can cause permanent damage, so it's important to treat a water stain on silk with care.
Similarly, silk can be handwashed, but doing so may change the lustre and drape of the fabric. If you have a silk garment made from particularly delicate silk, like chiffon or georgette, it's best to take it to a dry-cleaner as these fabrics are more likely to be affected by water.
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 silk clothes in cold water
Fill a clean sink or small tub with lukewarm water and a small amount of delicate-friendly liquid detergent. Lightly agitate for three to five minutes and rinse well. If the care label advises machine washing, choose a gentle, cold-water cycle.
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.
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.
Silk is one of the strongest natural fibers, but it loses up to 20% of its strength when wet. It has a good moisture regain of 11%. Its elasticity is moderate to poor: if elongated even a small amount, it remains stretched. It can be weakened if exposed to too much sunlight.
Shrinking Silk
Silk can shrink if it is pre-washed for more than approximately five minutes. Letting a silk garment sit in water for a long time before washing causes its fibers to tighten and twist, thus producing a shrinking effect. Silk that is washed in hot water will also shrink.
The Roman Senate tried in vain to prohibit the wearing of silk, for economic reasons as well as moral ones. The import of Chinese silk resulted in vast amounts of gold leaving Rome, to such an extent that silk clothing was perceived as a sign of decadence and immorality.
However, conventional silk is not made ethically as it requires boiling live silkworms while still in their cocoons, and child labor is not uncommon in this industry. It's also not sustainable because sericulture is very energy and water-intensive, and a lot of chemicals are added to the fabric.
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.
DO immerse the silk in cold water tonight (or as soon after painting as possible) and hang to dry, then iron after at least 48 hours, as shown above. After that, if you desire to soften it more, just put some liquid fabric softener and cold water in a bowl or sink, add your silk and swish a few times.
The first thing you need to know about how to dry silk pillowcases is that you should never put them in the dryer. The high heat of a dryer — even on a low setting — will destroy the silk's fiber.
