As the mornings get crisp, the sweaters come out of hiding. They’re the backbone of a fall and winter wardrobe: easy to layer, comfortable and endlessly versatile. But knits are also among the easiest pieces to ruin, whether that’s a shrunken wool pullover, a cardigan stretched out on a hanger or a cashmere crewneck covered in pills.

The good news is that a little care goes a long way. With the right habits, a good sweater can stay in your rotation for many seasons. Here’s how to keep your knits looking their best.

Start with the care label

Every sweater is a little different, so check the label before you do anything else. It tells you the fiber content and whether the piece can be machine washed, hand washed or should be dry cleaned only. When a label says “dry clean only,” it’s usually safest to follow it, especially for structured or embellished pieces.

As a general guide:

  • Wool and cashmere are warm and naturally odor resistant, but they can shrink and felt with heat and agitation.
  • Cotton knits are sturdier and often machine washable, but they can stretch when wet.
  • Synthetic blends such as acrylic or polyester tend to be easy care but are more prone to pilling.

Wash less often

Sweaters don’t need to be washed after every wear, especially wool, which resists odors. Air them out between wears by laying them flat or draping them over a chair overnight. Spot clean small marks when you can. Washing less often is one of the simplest ways to make knits last longer.

How to hand wash a sweater

Hand washing is the gentlest option for wool and cashmere:

  • Fill a clean sink or basin with cool or lukewarm water. Avoid hot water.
  • Add a small amount of gentle detergent or a wash made for wool.
  • Turn the sweater inside out and submerge it. Gently swish and press it for a few minutes. Don’t rub or scrub.
  • Let it soak briefly, then drain and rinse with cool water until the soap is gone.

If your machine has a wool or delicate cycle and the label allows it, you can use that instead. Place the sweater in a mesh laundry bag and use cold water.

Dry flat, never wring

This is where most sweaters get ruined. Never wring out a wet knit, and keep wool and cashmere out of the dryer unless the label says otherwise.

Instead, gently press out the water, then lay the sweater on a clean towel and roll it up to absorb more moisture. Unroll it and lay it flat on a dry towel or a drying rack, reshaping it to its original size. Keep it away from direct heat and strong sunlight, and flip it once to help it dry evenly.

How to remove pills

Pills are those little fuzzy balls that form where fabric rubs, such as under the arms or along the sides. They’re normal and don’t mean a sweater is poor quality, but they can make it look tired.

You have a few options:

  • A sweater comb or stone gently lifts pills off delicate fibers like cashmere.
  • An electric fabric shaver works quickly on thicker knits.
  • In a pinch, careful passes with a clean razor can work on sturdy fabrics.

Lay the sweater flat, work in small sections and go lightly. Washing inside out and avoiding rough bags or straps can help reduce future pilling.

Smooth wrinkles the gentle way

Skip the hot iron. A handheld steamer is the easiest way to refresh a knit, or you can hang it in the bathroom while you shower. If you do iron, use a low setting with a pressing cloth between the iron and the sweater.

Fold, don’t hang

Hanging heavy knits on hangers can stretch the shoulders and leave bumps. Fold sweaters and store them on a shelf or in a drawer, with heavier pieces at the bottom of the stack. If you need to hang one, fold it over the bar of a hanger rather than hanging it by the shoulders.

Keep moths away

Clothes moths are drawn to natural fibers, especially ones that carry body oils or food traces. Before storing sweaters for long periods, make sure they’re clean. Store them in breathable cotton bags or lidded bins, and add cedar blocks or lavender sachets. Check stored knits occasionally and refresh the cedar by lightly sanding it.

Wrap-up

A great sweater is an investment in comfort. Wash less often, choose cool water and gentle handling, dry flat, remove pills as they appear, and fold rather than hang. Treat your knits well this fall and they’ll be ready to wear again next year, and the year after that.
