Rule Number One: use shampoo to wash your silks, not dish liquid, woolite, or laundry detergent. Silks (and wool) are protein fibers, just like your hair, so use shampoo. You don't ever want to use Biz on silks. The enzymes are very bad for these protein fibers.
*For best results, use a little less than two teaspoons (9.5 mL) of Dawn® Platinum in a top-loading washing machine—be sure not to use too much, and don't use on delicate fabrics like silk. Spot test with a small drop in a less visible area to make sure the material will not be damaged.
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.
Whitehurst recommends using a mild shampoo, like Ivory, or gentle detergent, like Woolite. Place the garment in the water, give it a stir, and let it sit for just a few minutes.
The detergent you use must not have protease, enzymes, alcohol, bleach, or any alkalines in it: these will dissolve silk and any other protein-based natural fabric, such as wool. So when clothing directions say to use a gentle detergent, they mean a detergent without those ingredients.
Never wash with chlorine bleach. It can damage your clothing's natural fibers. Do not dry in direct sunlight. Exposing your garment to long bursts of sunlight can cause the colors to fade or even damage your silk fabrics.
This means that heavy-duty detergents meant for cotton or synthetic fibers just simply won't do. “To increase the longevity of your silk garments, we recommend handwashing them in cold water with a quarter teaspoon of gentle organic detergent and fabric softener for no more than five minutes,” offers Kes.

Detergent can stiffen silk
Even if you are hand washing your silks are per the instructions, if you are using a detergent, they can become stiff. Using a castile soap like Dr Bronner's instead can help a lot. Even after air drying, though, your silk may still be a bit stiff.
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.
Considering the above analysis of some of the key ingredients of Dawn dish soap, we would have to conclude that no, Dawn is not an environmentally friendly product. It contains one or more ingredients that are potential groundwater contaminants. They can pollute the water system and can harm fish or marine life.
Dish soap is also highly concentrated, so it might take several rinses to properly remove it from your clothes, wasting water. Even then, you might feel a waxy residue on the pieces or notice that towels or fleece pieces seem matted rather than fluffy.

As with any cover, it's important to wash your silk pillowcases once a week to avoid bacteria buildup.
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.
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.

Silk is a delicate fabric, and traditional laundry detergents can be too harsh and cause damage. Bleach and fabric softener should also be avoided, as they can also cause the fibers to break down over time. Furthermore, silk should be washed in cold water, as hot water can also cause damage.
