Listen to an audio transcription of this post

Key takeaways:

  • Silk is a delicate, protein-based fabric that requires special care, including using silk-safe detergents.

  • Regular detergents can damage silk as their higher pH levels strip silk of its natural proteins.

  • The ideal silk detergent, like Blissy Wash, is pH-balanced and free of harsh chemicals to maintain the fabric's luster.

  • Use a mesh laundry bag and gentle cycle in cool water when machine washing silk.

What Is Silk and Why Does It Need Special Care?

Silk is a natural protein fiber that comes from the silkworm Bombyx mori. It's known for being strong, smooth, and very lustrous, which is why it's often used in high-end clothing and accessories.

Silk pillowcases and silk bedding are becoming increasingly popular, as they provide many benefits for both sleep and beauty. Although strong, silk is a delicate fabric, and it needs to be treated with care in order to prevent damage.

Can I Machine Wash Silk?

For a long time, machine washing or even hand washing silk was a total no-no and a quick way to ruin your expensive silk garment. Taking your silk fiber item to the dry cleaner was thought to be the only safe way to get it clean.

Luckily, nowadays you can find silk that is machine washable. Which is fabulous because who has time to go to the dry cleaner?

But word to the wiseeven though silk is machine washable, that doesn't mean it's a total free-for-all in your laundry room when you wash your silk. You should take special care when you machine wash your silk:

  • Avoid fabric softener
  • Avoid chlorine bleach
  • Use cool water
  • Make the right detergent choice

Why Use Silk Detergent?

Silk is also a delicate fabric, so it needs to be handled with care to avoid damage.

Why can't I use regular detergent?

Using a regular laundry detergent on silk can cause damage to the fabric. That's because most laundry detergent you find contains powerful cleaning agents formulated for use on cotton or synthetic fabrics.

Cotton is a rugged fabric that can withstand all sorts of harsh chemicals and battery in your washer and dryer.

Depending on the synthetic fabric, it may or may not be able to withstand a lotbut it's not as important to care for delicate items made from synthetic fabrics as it is with silk as synthetic fabrics are cheap and replaceable.

Silk on the other hand is a luxurious fabric that is not as easily replaceable.

different laundry detergents

Silk's natural fibers respond differently to washing than cotton and synthetic fabrics do. That's why it's important to use a silk-specific detergent with a neutral pH when washing silk items.

What's the Difference Between Silk Detergent and Regular Detergent?

The main difference between silk detergents and regular detergents is the pH level. Regular detergent has a higher pH level, which can strip silk of its natural proteins and cause it to break down over time. Silk detergent has a neutral pH level, which is gentle on both delicate silk, silk wool, and your skin.

How Do I Pick the Right Silk Detergent?

The best detergent for silk is designed specifically for silk fabrics. It's usually pH-balanced and doesn't contain any harsh chemicals or fragrances that could strip silk of its natural proteins.

When shopping for silk detergent, look for a product that's specifically designed for silk and other delicate fabrics like wool. A gentle silk wash is especially important if you have sensitive skin.

Can I Use Wool Detergent When Washing Silk?

Wool detergent can be used on silk, but it's important to choose a product that is designed for both silk and wool. A wool-specific detergent may be too harsh for silk fabrics.

When in doubt, always err on the side of gentleness when washing silk. A silk-specific detergent like Blissy Wash Luxury Delicate Detergent will usually give you the best results.

Why Is pH Balance Important for Silk?

The pH level of a detergent is important because it determines how acidic or basic the solution is. A neutral pH level is around 7, which is neither acidic nor basic.

A silk garment should always be washed in a detergent with a neutral pH level. This will help preserve the silk fabric and prevent it from breaking.

How Do I Use My Silk Wash?

Machine washing with Blissy Wash

  1. For best results, place your silk items in a mesh laundry bag. Silk items should be washed separately from abrasive garments like denim, towels, or any garments with hooks, zippers, or other hardware.
  2. Add cap full of liquid to your machine's detergent dispenser. If your machine doesn't have a dispenser, we recommend mixing the detergent with the water first, then adding your items in. Don't pour detergent directly on the dry silk.
  3. Wash your silk garments on the delicate cycle or gentle cycle in cool or cold water.
  4. Hang silk items to dry (or lay flat on a mesh drying rack). Do not put silk in the dryer, as this can damage the fabric.

How to hand wash silk with Blissy Wash

If you only have an item or two like a silk pillowcase and some scrunchies, hand washing may be the most convenient option.

  1. Start by adding 2 tablespoons of gentle silk wash to a sink or basin of cold water.
  2. Gently swirl the silk around, taking care not to rub or wring it.
  3. Rinse the silk thoroughly in cool water
  4. Gently squeeze out any excess water. Place the item on a dry towel and gently roll it to further extract excess moisture.
  5. Hang the silk item to dry (or lay flat on a mesh drying rack).

How to iron silk

If you need to iron your silk pillowcase or other item, set your iron to the silk setting and make sure there is no steam. Place a silk-safe pressing cloth over the item, then iron until wrinkle-free.
