Knitwear is one of the coziest things you can wear—soft, warm, and often made with care. But because knits are delicate, they need a little extra attention when it’s time to wash and dry them. The wrong treatment can cause shrinking, felting, or stretching. Here’s a guide to help you care for your knitwear so it stays beautiful and soft for years to come.

Know Your Material – The Key to Proper Care

Before you even think about turning on the washing machine, check what your knitwear is made of. Wool, alpaca, mohair, cotton, and synthetic fibers all require different care.

• Wool and alpaca: Natural fibers that are self-cleaning and rarely need washing. They can only handle gentle treatment and cool water.
• Cotton: More durable and can usually be washed at higher temperatures, but it may lose its shape if hung to dry.
• Synthetic fibers: Easy to wash, but they can become static or stiff if exposed to too much heat.

Always read the care label—it’s the best guide for how to treat your specific garment.

How to Hand Wash Knitwear

Hand washing is the gentlest method, especially for wool and hand-knit sweaters. Fill a basin with lukewarm water (no warmer than 85°F) and add a small amount of wool detergent. Avoid regular laundry detergent—it can damage the fibers.

Place the knitwear in the water and let it soak for 10–15 minutes. Move it gently through the water, but don’t wring or rub it, as that can cause felting. Rinse in clean, cool water until all soap is gone.

When finished, press out the water gently—never twist or wring. Lay the garment flat on a clean towel, roll it up, and press lightly to remove excess moisture.

Machine Washing – Only If Your Washer Can Handle It

Many modern washing machines have a wool or delicate cycle that’s gentle enough for knitwear. But it only works if the machine can maintain a steady, low temperature and minimal agitation.

Always use a mesh laundry bag to prevent stretching, and choose a mild wool detergent. Skip the fabric softener—it can coat the fibers and make them stiff.

Remove the knitwear from the machine as soon as the cycle ends. Leaving it wet and crumpled can cause it to lose its shape.

Drying – The Most Important Step

Drying is often what determines whether your knitwear keeps its shape. Never hang knits to dry—the weight of the water will stretch them out. Instead, dry them flat.

Lay the garment on a dry towel on a flat surface and gently reshape it while it’s still damp. Smooth out the edges and sleeves so it returns to its original form. Replace the towel if it becomes too wet, and let the knitwear dry at room temperature—away from direct sunlight or heat sources like radiators.

If you need to speed things up, use a drying rack with a mesh surface that allows air to circulate underneath. It shortens drying time without distorting the shape.

Freshening Up Without Washing

Often, knitwear doesn’t need a full wash at all—airing it out can work wonders. Hang the sweater outside in the shade for an hour or two, and it will feel fresh again. Wool has natural antibacterial properties that help eliminate odors on its own.

If your knit looks a bit wrinkled, use steam from an iron or a garment steamer. Hold it a few inches above the fabric and let the steam lift the fibers—this restores both softness and freshness.

Storing Knitwear – Avoid Stretching and Moths

When you’re not wearing your knitwear, fold it instead of hanging it. Hanging can stretch out the shoulders and distort the shape. Store it in a cool, dry place, and consider adding a sachet of lavender or cedar to keep moths away.

If you’re packing knits away for the season, make sure they’re completely clean and dry—moths are attracted to sweat and food residues.
