A KAILU duvet — meticulously crafted of raw silk that is organically farmed, harvested, and hand stretched by passionate and infinitely patient artisans — can last 15 to 20 years if you treat it with care. Raw silk contains a natural protein called Sericin, which many researchers say reduces the possibility of allergic reactions and discourages microbial growth. Exposure to water and intense heat can degrade these unique protections, not to mention make the raw silk clump and stick together.
Please read the following tips carefully to ensure your KAILU raw silk duvet maintains its unique protections and stands the test of time.
WASH THE DUVET COVER ONLY
We designed our duvets with a removable duvet cover to protect the raw silk and to feel luxurious next to your skin. To wash, remove your duvet cover and machine wash it separately with lukewarm water and gentle detergent, tumble dry low, and, if you prefer a crisp look, use an iron on a medium or lightweight cotton setting.
SUN FRESHEN
One to two times per year, place your raw silk core outside on a sunny day to sun cure it without chemicals. Lay it flat or drape it over a drying rack for about an hour, and then flip it over for another hour. Protect it from dirt and debris by keeping the duvet cover on or using a light sheet.
SPOT CLEAN
If a spill happens, immediately remove the protective duvet cover to machine wash it. Then spot clean the silk core(s) using a mixture of cold water + white vinegar + baking soda and gently dabbing with a damp sponge. Do not soak. Let the silk core air-dry. Repeat, if needed.
DRY CLEAN
If your duvet requires a deep clean, ask a trusted dry cleaner to pin the raw silk in place and to use hydrocarbon solvents, which are gentler and have a longer cleaning cycle than conventional professional cleaning chemicals (not to mention less harmful to workers and the environment).
DON’T WASH THE RAW SILK CORE
We never recommend machine washing or wet cleaning the raw silk core, as this will make the layers stick together, degrade the silk, and shorten the lifespan of your duvet.
PERFECTLY IMPERFECT
Inside each KAILU duvet and throw is the highest-grade long-strand mulberry silk. The silk is “unreel” — it is left in its fluffy raw form to retain its unique wellness benefits: hypoallergenic, naturally temperature regulating, and supremely breathable.
