As winter storms continue to blanket much of the United States, a surprising cleaning trend has emerged online: snow washing, or using snow to clean woolen garments. What began as a cabin-fever solution for those stuck indoors is gaining traction on social media, prompting many to wonder if this unconventional method is actually effective—and safe—for their clothes. The practice, rooted in a Nordic tradition, is now being examined by textile experts and put to the test by everyday consumers.
The idea is simple: instead of traditional washing machines and detergents, wool items are submerged in piles of fresh snow. But is this just another internet cleaning hack destined to fail, or is there a legitimate benefit to letting Mother Nature handle laundry day? Experts say the key lies in the unique properties of wool and the specific conditions required for successful snow washing.
The Science Behind Snow Washing
Renzo Shamey, a textile expert and director of the Color Science and Imaging Labs at North Carolina State University, explains that wool fibers have scales that can shrink and felt when exposed to heat, agitation, or excessive moisture. Felting occurs when these fibers fuse together, altering the material’s texture and shape. Snow washing, however, provides a cold-temperature wash that minimizes agitation and reduces the amount of moisture the wool absorbs, potentially leaving garments feeling softer.
Fran Kozen and Larissa Shepherd, fiber science and apparel design experts at Cornell University, further elaborate that the gentle nature of snow washing helps preserve the integrity of wool fibers. “When washing wool, you don’t want much agitation and heat because that can cause the scales to open and, if allowed to dry with heat, it would felt,” Shepherd said. The process is particularly well-suited for bulky items like rugs and blankets, which can be challenging to launder conventionally.
Not All Wool is Created Equal—and It’s Not for Everything
While snow washing shows promise for certain wool types, it’s not a universal solution. The method is specifically recommended for wools including lambswool, angora, mohair, alpaca, and cashmere. It’s crucial to remember that this technique is intended only for wool garments. Other fabrics are not suitable for this cleaning method.
Successful snow washing as well depends on the quality of the snow itself. According to Kozen, the snow must be dry and fluffy, not wet or compacted. “The snow must be the dry, fluffy sort,” Kozen says. “Brushing the item lightly with the slightly abrasive dry snow crystals helps remove light surface dirt.” Items should also be thoroughly chilled before being placed in the snow to ensure optimal results.
A Nordic Tradition Gains Modern Life
Snow washing isn’t a new phenomenon; it’s a long-standing tradition in Nordic countries. As described in Country Living, it’s often referred to as “snötvätt” in Swedish and is seen as a natural and free way to freshen up textiles. The recent surge in popularity is largely attributed to social media platforms like TikTok and Instagram, where users are sharing their experiences and results.
The trend has resonated with knitters and fiber enthusiasts who appreciate the gentle and environmentally friendly approach to cleaning delicate wool items. It offers an alternative to dry cleaning, which often involves harsh chemicals, and provides a way to care for treasured garments without the risk of damage from traditional washing machines.
What About Other Garments?
While wool is the ideal candidate for snow washing, experts caution against using this method on other fabrics. The unique structure of wool fibers allows them to withstand the cold, gentle cleaning process without significant damage. Other materials may not respond as well and could potentially be harmed.
For garments that aren’t suitable for snow washing, traditional cleaning methods are still recommended. This includes machine washing with appropriate detergents, hand washing, or professional dry cleaning, depending on the fabric and care instructions.
As the snow continues to fall across many regions, the snow washing trend is likely to persist. While it may not replace conventional laundry methods entirely, it offers a unique and surprisingly effective way to care for wool garments, connecting modern cleaning practices with age-old traditions.
The long-term effects of repeated snow washing on wool garments are still being observed, and further research may be needed to fully understand its impact. However, for those looking for a gentle and natural way to refresh their woolens this winter, snow washing presents a compelling option.
If you’re considering trying snow washing, remember to prioritize dry, fluffy snow, ensure your garment is thoroughly chilled, and stick to 100% wool items. Share your experiences and results online – the snow washing community is eager to learn from each other.
