Fill a basin with cold water and a washing detergent. Allow the silk negligee to soak for a few minutes. Avoid rubbing or scrubbing the material. Silk is a shiny material, and to maintain that shine, you will need a quarter of a cup of vinegar mixed in with about one litre of water. Use this mixture to rinse out the silk after having soaked it in with the detergent. Continue rinsing with a lot of water until the smell of vinegar is washed out.
When it comes to getting rid of the excess water, you should note that you should avoid wringing the material. This will damage it, as it is delicate. Instead, use two clean towels and place the silk negligee between them. Press down gently for the towels to soak up the excess water.
Hang the negligee on a hanger or rack. Avoid wood as the varnish present tends to stain on silk. Use padded hangers instead. When you want wear your silk negligee, iron it on the coolest setting. Another alternative not many people know of is to hang your negligee in the bathroom as you take a shower. The humidity will help in removing any wrinkles it may have had.
Another tip in protecting your silk negligee is to avoid using nail polish, perfumes or hair sprays before you wear it. If possible, use these substances before you wear your negligee, and allow them to dry. If any of these substances spill on your garment, they will leave a permanent stain.
Silk is best stored in cool, dark areas. This fabric is very sensitive to light, and will form discolorations if it is exposed to the sun. In addition to this, if you want to maintain the color of your negligee, you will need to avoid placing it in the sunlight because this causes it to fade. Avoid storing your negligee in plastic because silk is a material that needs to breathe. In as much as most silk negligees can be washed from home, some may require dry-cleaning. Read the instruction label on the negligee to determine whether you can hand-wash it or take it to the dry-cleaner’s.
