Silk is one of nature’s finest materials — strong yet delicate, luxurious yet functional. And while its softness feels effortless, maintaining that beauty requires mindful care. The good news: caring for ZILK silk isn’t complicated. It simply calls for intention. With the right approach, your pillowcases and sleep accessories will stay just as smooth, luminous, and skin-friendly as the day you bought them.
The Science Behind Silk Care
Silk is made of natural protein fibers, much like human hair. That’s why harsh detergents, hot water, or high heat can cause it to lose its smoothness or luster over time. ZILK’s 25 momme Mulberry silk is tightly woven for durability, but gentle care helps preserve its natural structure — keeping every thread resilient and soft.
Our proprietary NeuroSilk™ technology infuses silver ions into the fibers to help resist bacteria and odor. Proper washing ensures this smart fabric continues to perform its best, supporting both skin health and restorative rest.
Step 1: Wash with Intention
Whether you prefer hand or machine washing, gentle is the rule.
Hand Washing:
-
Fill a clean basin or sink with cool to lukewarm water.
-
Add a few drops of silk-safe detergent — avoid enzyme-based or brightening formulas.
-
Swirl gently for 3–5 minutes. Never scrub, wring, or twist.
Machine Washing:
-
Place your silk items in a mesh laundry bag to prevent snagging.
-
Use the delicate or silk cycle with cold water and a mild detergent.
-
Wash separately from heavy items like towels or denim to prevent friction damage.
Pro tip: If your washing machine allows, turn off spin cycles — excess agitation weakens silk fibers over time.
Step 2: Rinse with Care
Rinse thoroughly with cool water to remove all traces of detergent. To preserve the fabric’s softness, you can add a few drops of distilled white vinegar to your final rinse. It restores silk’s natural pH balance and helps maintain sheen — the quiet glow that makes ZILK silk so recognizable.
Step 3: Dry the Gentle Way
Lay your silk flat on a clean, dry towel. Roll gently to absorb excess water, then unroll and air dry flat or hang in the shade. Avoid direct sunlight, which can weaken the fibers and fade the color over time. Never tumble dry — the high heat dehydrates silk and breaks down its natural proteins.
If ironing is needed, use the lowest heat setting while the fabric is still slightly damp. Place a cotton cloth between the iron and the silk to protect the weave.
Step 4: Refresh and Store Thoughtfully
Keep your silk fresh between washes by giving it time to breathe. Avoid storing it in plastic bags or airtight containers — natural fibers need airflow. A cool, dry drawer lined with tissue or cotton is ideal.
Why It Matters
Proper care doesn’t just extend the lifespan of your silk — it protects the wellness benefits you invested in. Clean silk supports clearer skin, healthier hair, and better rest by maintaining a fresh, hypoallergenic sleep surface. Each wash renews the ritual of restoration that ZILK stands for: calm, clean, and clinically considered beauty sleep.
The Ritual of Restoration
Washing your silk isn’t a chore — it’s a continuation of your self-care. When you handle your silk intentionally, you’re preserving more than fabric; you’re maintaining a nightly ritual that supports your skin, hair, and sense of calm. With ZILK, beauty care and fabric care become one seamless, restorative cycle.
