How to Wash Silk

Silk Basics

Silk is a natural protein fiber composed mainly of fibroin and produced by certain insect larvae when they form cocoons (source: Wikipedia). It’s naturally produced without using harsh cleaning ingredients.

Why does silk require special care when washing? Silk is incredibly delicate. Just think about where it came from—tiny bugs. Whether you’re washing silk by hand or in a machine, there are a few rules you’ll want to bear in mind to protect that special garment.

What to Avoid When Washing Silk

Because the fabric is so delicate, there are a few best practices when it comes to washing silk. Listed are a few common laundry techniques that you should avoid:

  1. Harsh ingredients, specifically bleach. Bleach will damage the natural fibers.
  2. Do not tumble dry. High temperatures from a dryer can shrink or damage your silks.
  3. Avoid enzymatic stain pre-treatments (like OxiClean or select detergents). These are meant to clean protein stains from more durable fabrics, meaning they’re not good for a protein fabric like silk.
  4. Avoid drying your garment in the direct sunlight, this can cause the colors to fade.

How to Wash Silk in a Washing Machine

Sometimes there just isn’t enough time (or energy) for hand washing – and sometimes that’s ok! Here are the best ways to clean silk using your traditional washing machine:

  1. Wash only with other delicate, light-weight fabrics.
  2. Wash in a mesh garment bag.
  3. Add a gentle detergent, such as:
    1. Soak – Soak is skin- and fabric-friendly, as it’s made without harsh chemicals or overwhelming fragrances. Plus, their bottles, caps and labels are recyclable and printed with water-based inks.
    2. Laundress – An allergen-free non-toxic formula specifically formulated for delicate wash cycles (like silk!).
  4. Wash on a delicate cycle.
  5. After washing, roll the damp garment in a dry towel to remove any excess moisture. Then hang or lay flat to dry.
