Why Experts Say Freezing Your Cashmere Sweaters Still Makes a Difference

"If you've ever pulled out a beloved sweater only to discover tiny holes, that means you have a moth problem, and that can be devastating to your clothes. Freezing cashmere can help kill existing moths or larvae before seasonal storage. "Freezing cashmere sweaters will help kill moths, but it won't prevent a future moth infestation," explains personal stylist Dianne Boyer. She recommends freezing sweaters before storing them for the season so you don't tuck moth larvae away with your knits."

"Freezing can also slightly reduce shedding (emphasis on slightly). "The freezing will help tighten the fabric," says Boyer, which can keep fibers in place for a short time.But don't expect miracles. "Freezing can hold the fibers in place and therefore reduce shedding," Hernandez explains, "but it's temporary. As the fibers return to normal temperature, this effect will be gone." For longer-term results, a cashmere comb is still your best bet for both shedding and pilling."

Freezing cashmere kills existing moths and larvae and is recommended before seasonal storage to avoid preserving larvae in garments. Freezing will not prevent future moth infestations, so additional preventive measures and proper storage remain necessary. Freezing can temporarily reduce odors in cashmere items. Freezing can slightly reduce shedding by tightening the fabric and holding fibers in place for a short time, but the effect dissipates as fibers warm to normal temperature. For longer-term reduction of shedding and pilling, using a cashmere comb is the more effective solution.
