Article: Even if the care label on the shirt does not say that it's dry-clean only, it's a good idea to test the material and make sure it won't be damaged by water. Take the corner of a white towel or washcloth and wet it slightly in the sink, then gently dab the shirt in an inconspicuous place, like the armpit or under the collar. If any color comes away on the towel, your shirt should be dry-cleaned. Be careful not to rub the silk with the towel, as it may damage the fabric. Make sure the bowl is large enough that you will be able to submerge the entire shirt once it's full. Keep the water tepid or a little on the cool side. Look for soaps or detergents that are labeled "mild" or "sensitive," as they will typically have a lower pH. Silk is very delicate, and harsh soaps can be harmful to the fibers. It's also a good idea to avoid any added fragrances or dyes. Gently stir the shirt around in the water with your hand, being careful not to rub the fabric. Do this for a couple minutes, then let it sit. Make sure your shirt is not in the water for more than a total of 5 minutes. Squeeze the shirt in your hands until it stops dripping continuously. Be careful not to twist or wring it. You can empty the original bowl and use it again, but make sure you've rinsed any soap residue out of the bowl before you fill it with rinse water. This will help neutralize any leftover soap, and keep the residue from damaging your shirt. It will also help neutralize any odors that may have been in the shirt. Again, be careful not to rub or wring the fabric as you swirl it in the water. This should remove any soap residue left in the fibers. Remove the shirt from the water and gently squeeze out any excess moisture, then place it in a clean bowl of water for a final rinse. You can add a few drops of hair conditioner to this rinse water to keep the fabric soft and add a pleasant smell.
