One of the quiet luxuries of alpaca wool is how little it asks of you. It resists odor naturally, shrugs off wrinkles, and softens with wear instead of scratching. But like any natural fiber worth investing in, a few small habits will keep your alpaca pieces looking and feeling their best for years—which is really the point of buying well in the first place. Fewer replacements, less waste, more wear. Here's our care guide, drawn from how we treat our own alpaca knitwear at home.
Washing Your Alpaca Wool
Hand-wash in cold water whenever possible. Fill a basin with cool water and a small amount of a pH-neutral, wool-safe detergent, then submerge the garment and gently agitate it for a minute or two—no scrubbing, no wringing. Alpaca fibers are naturally strong, but hot water and rough handling can cause them to felt or lose their shape. If a stain needs extra attention, treat it gently before the full wash rather than scrubbing at it directly.
Many alpaca socks and machine-washable knitwear can go in the machine on a cold, delicate cycle inside a mesh garment bag—but always check the care label on your specific piece first, since finishing and blends vary. When in doubt, hand-washing is the safer choice.
Drying Without Stretching
Never wring or hang a wet alpaca garment to dry—the weight of the water will stretch the fibers out of shape. Instead, gently press out excess water, lay the piece flat on a clean towel, and reshape it to its original dimensions. Roll the towel up to absorb more moisture, then let it finish air-drying flat away from direct sun or heat sources like radiators, which can dry the fibers out.
Storing Alpaca Between Seasons
Sweaters and knitwear should always be folded, never hung—hanging stretches the shoulders and neckline over time. Store folded pieces in a breathable cotton bag, pillowcase, or drawer rather than sealed plastic, which traps moisture. Make sure everything is clean and completely dry before it goes into storage, since moths and other pests are drawn to body oils and residue, not the fiber itself.
For natural moth deterrence, cedar blocks or lavender sachets tucked into the storage bag are a gentle, chemical-free option. It's also worth storing alpaca separately from sheep's wool or cashmere pieces, since moths tend to be drawn to those fibers first.
Preventing (and Fixing) Pilling
Some pilling is normal for any knitted fiber, especially in high-friction spots like underarms or where a bag strap sits. The good news: it's easy to manage. Wash gently and infrequently, air out worn pieces between wears instead of always washing, and rotate your knitwear so no single piece takes on all the friction.
If pills do form, don't reach for a razor or scissors. A wool comb or fabric shaver, used gently and along the direction of the fibers, lifts pills away without damaging the knit underneath.
FAQ: Alpaca Wool Care
Can I put alpaca wool in the dryer?
We don't recommend it. Heat and tumbling can shrink or felt the fibers and cause excess pilling. Air-drying flat is always the safer route.
Is alpaca wool machine washable?
Some pieces are, on a cold, delicate cycle in a mesh bag—but always check the specific care label first, since it depends on the knit and finishing. Hand-washing is the gentlest option for any alpaca garment.
Why is my alpaca sweater pilling?
Pilling happens from friction during normal wear, not from poor-quality fiber. Washing gently, drying flat, and rotating what you wear all help minimize it.
Do I need mothballs to protect alpaca wool?
No—traditional mothballs use harsh chemicals. Cedar and lavender are effective, natural alternatives, and keeping garments clean before storage matters just as much.
How often should I wash my alpaca knitwear?
Less often than you'd think. Alpaca is naturally odor-resistant, so airing a piece out between wears usually keeps it fresh without a full wash.
