Washing Silk Without Detergent: Gentle, Eco-Friendly Methods

Silk is one of the most elegant and luxurious fabrics, but it requires delicate care.

Traditional laundry detergents can actually damage silk fibers and cause items to lose their sheen and vibrancy over time.

As someone who loves silk clothing and wants to keep pieces in pristine condition for as long as possible, I searched for the best methods to wash silk gently and naturally.

In this article, I’ll share eco-friendly techniques for washing silk without harsh detergents. 

These methods are super easy, effective, and help preserve the integrity of your delicate silk items while avoiding harsh chemicals.

Read on to learn how to care for your silk sustainably!

Why Chemical Detergents Can Harm Silk

Before jumping into the natural silk washing methods, let’s review why it’s best to avoid regular detergents when cleaning silk fabrics.

Here are some of the biggest risks that traditional laundry detergents pose to your precious silk clothing and accessories:

• Fading colors – The chemicals, bleaches, and brighteners in detergents can cause silk dye to fade significantly over time.
• Loss of sheen & luster – Detergents strip the natural sericin finish from silk, leading to a dull, lackluster appearance.
• Weakened fibers – Harsh detergents damage silk’s delicate protein fibers, causing items to wear out faster.
• Shrinkage – Silk is prone to shrinkage, which is exacerbated by the harsh chemicals in typical laundry products.
• Residual detergent – Most detergents leave behind a residue that can attract dirt over time.

To keep silk looking its absolute best for a long time, I only use gentle, natural cleaning methods. Let’s get into the techniques!

Method 1: Washing Silk with Just Water

For lightly worn silk items that just need a quick refresh, washing with plain water is my go-to method. Here are the steps I follow:

Step 1 – Fill a Sink/Basin with Lukewarm Water

• Avoid using hot water, as high heat can cause silk to shrink. Lukewarm water is safest.
• Swirl water gently to create movement without agitation.

Step 2 – Immerse the Silk Item & Allow It to Soak

• Keep soaking time brief – 3 minutes max.
• For stubborn spots or stains, gently massage the area with your fingers.

Step 3 – Drain Water & Refill Basin

• Drain the sink and refill it with clean lukewarm water for rinsing.
• Repeat the soak and rinse cycle up to 3 times until the water runs clear.

Step 4 – Roll Silk Item in a Towel to Remove Excess Moisture

• Lay a fresh towel on a flat surface.
• Roll the silk item up loosely in the towel.
• Apply light pressure to absorb wetness.

Step 5: Dry Flat on a Mesh Laundry Rack or Towel

• Lay the silk piece smoothly on a towel or mesh drying rack.
• Reshape as needed while still slightly damp.
• Allow to fully air dry before wearing or storing.

While it may seem too simple, washing silk in plain water truly does wonders for freshening up pieces between deeper cleanings.

It’s chemical-free and prevents buildup of detergent residues over time.

Method 2: Using a Vinegar Rinse for Silk

For more thorough silk cleansing, I like to use a dilute vinegar solution.

The vinegar helps remove traces of dirt, sweat, and other impurities, without stripping away the silk’s natural finishes. Follow these steps:

Step 1 – Fill Sink Basin with Cool Water

• Use cool, not cold water. Temperatures below lukewarm can cause silk fibers to constrict.
• Add 1 tablespoon of distilled white vinegar per 1 quart of water. Too much vinegar can be harsh on silk.

Step 2 – Swirl the Item in Vinegar Solution for 2-3 Minutes

• Avoid vigorous swirling or agitation that could damage delicate silk.
• For stubborn stains, gently massage vinegar into the spot.

Step 3: Drain First Vinegar Solution & Rinse

• Drain the vinegar solution and refill the basin with clean, cool water.
• Allow the item to rinse for 1-2 minutes.

Step 4: Repeat Rinse Cycle

• Drain rinse water, refill basin, and repeat rinse cycle.
• Rinsing thoroughly removes the vinegar solution.

Step 5 – Roll in Towel and Allow to Dry

• Follow the same towel rolling and drying techniques from Method 1 above.

I like using a vinegar soak and rinse for silk about once per month. Vinegar is gentle, removes residue, and helps maintain the luxurious drape and feel of silk.

Just be sure to fully rinse away the vinegar smell!

Method 3: Baking Soda as a Natural Silk Cleaner

For occasional deeper cleansing, baking soda mixed with water makes an effective natural silk detergent alternative. Here’s my process when using it:

Step 1 – Make a Paste with Baking Soda

• Dissolve 1 tsp baking soda in 1 cup cool water.
• Stir until it forms a spreadable paste.

Step 2 – Gently Massage Paste into Silk

• Focus on soiled areas but don’t over-scrub.
• Ensure the paste fully penetrates stained regions.

Step 3 – Rinse Thoroughly

• Rinse with lukewarm water until all baking soda residue is removed.
• Add an extra rinse cycle if needed.

Step 4 – Roll and Dry as Usual

• Roll the silk item in a towel to absorb moisture.
• Lay flat to air dry fully before wearing or storing.

I find baking soda works nicely to lift away body oils, perspiration, and dirt that can accumulate on silk without being harsh.

Just don’t overdo it – once every 2-3 months is often enough.

Mild Liquid Soap Alternatives for Silk Washing

While I typically stick to just water, vinegar, or baking soda for washing my silk items, I know many people prefer to use a gentle liquid soap.

Here are some options I recommend exploring:

• Baby shampoo – Extremely mild and free of dyes/fragrances. Dilute substantially before use.
• pH-neutral wool detergent – Does not disrupt silk’s pH balance like most soaps.
• Castile soap – All-natural option made from plant oils. Dr. Bronner’s is a top brand.
• Silk-specific detergents – Products like The Laundress Silk Shampoo are designed for safety.

If opting for a liquid soap, dilute it significantly, use sparingly, rinse meticulously, and skip any fabric softeners or dryer sheets.

And incorporating water-only washes between detergent cleansings helps maintain silk’s integrity.

A Closer Look at Silk-Specific Detergents

While I often use eco-friendly methods for washing my silk items, I know many people prefer the convenience of a commercial silk detergent.

The key is choosing one that is specifically designed for delicates like silk.

Silk-specific detergents are far more gentle than traditional laundry products because they contain milder surfactants that don’t strip away silk’s natural oils and proteins.

They also have a neutral pH to match silk’s pH.

Here’s an overview of some top silk detergent options and how they compare:

If I had to choose one silk-specific detergent to recommend, it would be Heritage Park Laundry Detergent (link to Amazon). I find this product to be extremely effective yet gentle.

But no matter which silk-specific detergent you choose, it’s essential to:

• Pre-treat any stains to avoid excessive rubbing during washing
• Use very minimal amounts – over-sudsing can leave residue
• Rinse extremely thoroughly to remove all detergent
• Avoid fabric softeners or dryer sheets which coat fibers

With the proper silk detergent and care methods, your delicate fabrics can stay stunningly beautiful wash after wash.

Best Practices for Handling & Drying Silk

To keep silk looking beautiful wash after wash, follow these tips for handling and drying:

• Avoid twisting, wringing, or tossing silk when wet – support gently.
• Reshape garments on a towel before fully drying to prevent permanent creases.
• Roll necklines and collars of blouses on a towel to retain shape.
• For maximum luster, iron silk on low heat with steam using a press cloth.
• Store washed silk items for at least 24 hours before wearing them to ensure they fully dry.
• Allow silk to air dry naturally – skip the clothes dryer to prevent damage.
• Use rust-free hangers and garment bags to store washed silk items.

With proper handling, your silk garments and accessories will maintain their gorgeous drape and vibrancy for many washes to come.
