Silk Storage: The Complete Guide to Preserving Fabrics

I absolutely love silk. From blouses to dresses to scarves, silk adds elegance and luxury to any outfit.

However, silk is also a delicate fabric that requires proper care and storage to maintain its beauty over time.

In this article, I’ll share everything you need to know about preserving your precious silk items.

Why Proper Silk Storage Matters

Silk is made from delicate natural protein fibers that can easily be damaged by light, heat, moisture and insects.

Improper storage can cause silk to yellow, get mildew, or even rot and fall apart! Additionally, creases and wrinkles that set in silk become very difficult to remove.

By following the proper silk storage methods I’ll describe below, you can keep your silk looking and feeling brand new for many years to come.

Here’s what we’ll cover in this complete guide to storing your silk:

• Best practices for daily silk storage
• Long-term silk storage solutions
• Protecting silk from environmental damage
• Storing different types of silk items
• Recommended storage materials
• Maintaining silk quality over time
• And more!

Let’s start with some silk storage tips for day-to-day use when wearing or prepping your silk pieces.

Immediate Silk Storage: Best Practices for Daily Use

When wearing, hanging or folding silk on a regular basis, here are some best practices to follow:

Overnight Silk Storage

• Never leave silk crumpled up in a pile. This can cause deep creases that are difficult to remove.
• Carefully hang silk pieces overnight whenever possible using padded or covered hangers. This helps them keep their shape.
• If hanging isn’t possible, loosely fold silk and place it on a flat, cushioned surface.
• For extra care, wrap folded silk in a clean cloth or acid-free tissue paper overnight.

I love the Simetufy Acid-free Tissue Paper (link to Amazon) for storing my delicate silk garments; it keeps them safe and pristine without any worries!

Storing Silk in Drawers

• Use drawers that are specially designated for delicates like silk. Regular drawers may snag silk.
• Line drawers with acid-free, pH neutral paper before placing silk inside.
• Fold silk loosely rather than tightly before placing in drawers. Tight folds lead to stubborn creases.
• If the drawer contains other items, separate silk using archival tissue paper to prevent snagging.
• Avoid overstuffing drawers with too many silk items. The weight can cause damage.

Hanging vs. Folding Silk

• Hanging pros: Allows silk to keep its shape, minimizes creases
• Hanging cons: Can stretch out some silk fabrics over time on the hanger
• Folding pros: Takes up less space, easier for storage
• Folding cons: Can lead to difficult creases and wrinkles

As you can see, each method has its tradeoffs. I recommend hanging silk immediately after ironing/steaming and loosely folding for storage.

Long-Term Silk Storage Solutions

For storing silk items longer term during off-seasons, here are some best practices:

Ideal Conditions

• Temperature: 68-72° F
• Humidity: 50-55% relative humidity
• Lighting: No direct light or sunlight
• Ventilation: Good airflow, no musty smells

Ideally, store silk in an interior closet or dresser drawer in the bedroom, which often falls within the temperature and humidity recommendations.

Avoiding Wrinkles

The key is to evenly wrap and support the silk items to prevent folds and creases:

• Wrap silk item in a clean white cotton sheet or acid-free tissue paper
• Place a cardboard insert or archival board on each side for support
• Carefully put wrapped silk in an archival box, cedar chest or breathable garment bag
• Never overstuff storage containers, as excess weight can misshape silk

Moth Protection

To safeguard delicate silk from moths, beetles and other insects:

• Inspect regularly for any signs of insects
• Store with cedar products (blocks, chips, balls)
• Use an unscented moth repelling sachet
• Maintain clean storage areas without food debris
• Freeze silk for 72 hours before storage to kill any eggs/larvae

It is critical to safeguard delicate silk from moths and other insects. Silk fibers and fabrics can become food sources for larvae, which can cause extensive damage.

The Homode Cedar Blocks (link to Amazon) are perfect for protecting your silk fabric from moths—highly recommend!

Protecting Silk from Environmental Damage

Silk is highly prone to damage from light, heat, pollution and other environmental factors. Here is how to protect it:

Sunlight and Moisture

• Never display silk in direct sunlight, which causes fading and deterioration
• Avoid hanging silk near heating/AC vents where temperature fluctuates
• Use light-diffusing curtains on windows near silk
• Maintain 40-50% humidity in rooms where silk is stored
• Allow silk to air dry naturally – heat drying leads to brittleness

Preventing Static

To avoid static electricity that can attract damaging particles:

• Keep silk storage areas below 35% humidity
• Do not use plastic bags or containers to store silk
• Use anti-static sprays and acid-free tissue when wrapping silk

Silk Aging and Prevention

Over many years, silk can become stiff and brittle due to:

• Repeated heating and drying
• Harsh detergents stripping natural oils
• Pollutants and gases in the air

To prevent silk aging:

• Store silk properly using the tips in this article
• Display out of direct light and rotated with other pieces
• Hand wash with gentle silk detergent instead of dry cleaning

Heritage Park Laundry Detergent (link to Amazon) is my go-to for silk items. It’s incredibly gentle on the delicate fabric, ensuring that my silks last longer and stay gorgeous.

Storing Different Types of Silk

From storing antique silk clothing to silk sheets, here are some tips based on item type:

As shown in the table, some customization may be required based on the silk item but in general, the storage principles are the same.

Storage Materials: What to Use and Avoid

It’s just as important to use the right storage materials as it is to follow the proper storage methods:

Plastic Bags and Containers

• Pros: Convenient, transparent, widely available
• Cons: Can trap moisture and gases that damage silk
• Bottom line: Avoid plastic bags and opt for breathable materials

Recommended Storage Materials

• Acid-free, lignin-free tissue and paper
• Unbleached, undyed 100% cotton muslin and sheeting
• Archival grade boxes and paperboard
• Cedar chests, cedar boards, chips and blocks
• Breathable garment bags (cotton canvas or linen)

For the storage containers themselves:

• Good: Wood, wicker, acid-free cardboard, ceramics, metals
• Avoid: Plastics, vinyl, straw baskets (may have moisture issues)

No matter what materials you use, they should allow airflow while protecting silk.

Maintaining Stored Silk Over Time

To ensure long-lasting silk, follow these maintenance practices:

• Inspect at least twice a year for any insect damage
• Gently unfold and refold in opposite direction to avoid creases
• Lightly steam if creases set in
• Allow silk to air out for a few hours twice a year

How Long Can Silk Last?

• With improper storage: Silk may only last 10 years before deteriorating
• With proper archival storage: Silk can last 50+ years!

Signs of Deterioration

• Yellowing or darkening
• Increased stiffness and brittleness
• Visible damage from insects or moisture

If silk shows any of these deterioration signs, consult a textile specialist about possible restoration before further damage occurs.

What temperature is best for storing silk?

The ideal temperature range for storing silk is 68–72° Fahrenheit. Temperatures above 75°F can dry out silk fibers leading to brittleness over time.

Meanwhile, temperatures below 60°F can cause silk to become stiff. Maintain the 68-72°F range to preserve silk’s flexibility and sheen.

Can I vacuum seal silk in storage bags?

Vacuum sealing silk in plastic bags is not recommended.

Silk fibers require a bit of airflow even when in storage to prevent moisture buildup that can encourage mold growth.

Vacuum bags trap moisture next to silk. Instead of plastic vacuum bags, store silk in archival grade cardboard boxes, which allow more airflow. 

How often should stored silk be inspected?

Inspect stored silk at least two times per year – once halfway through the off-season and again when transitioning it back to everyday use.

Check for any early signs of insect damage like small holes or trails along seams. Also watch for odd musty odors, which may indicate moisture issues.

Is it okay to store silk in my attic?

Storing silk in an attic is risky due to temperature extremes. Attics can get very hot in summer months, exceeding 100°F in some regions.

Such sustained heat can dry out silk fibers leading to brittleness. In winter months, uninsulated attics can drop below freezing temperatures.

This cold causes silk to become stiff and risk tearing when handled. Instead, store silk year-round in interior closets near bedrooms on upper or lower levels of the home.
