Wash & Store a Cardigan Without Stretching or Pilling

This guide shows you how to wash and store a cardigan so it keeps its shape and stays free of fuzz balls. You’ll learn the right water temperature, how to dry it flat without stretching, and the best way to fold it in a drawer or hang it in a closet.

What You’ll Need

• Mild liquid detergent (wool or delicate wash preferred)
• Cool or lukewarm water
• A clean sink, basin, or bucket
• A clean, dry towel (large enough to roll the cardigan)
• A flat drying rack or a second dry towel
• Optional: a mesh laundry bag for machine washing
• Optional: a fabric shaver or sweater comb for existing pills

Step-by-Step

1. Read the care label. Check the tag inside the cardigan for fiber content and washing instructions. If it says “dry clean only,� follow that unless you’re confident hand washing is safe (e.g., 100% wool that can be hand washed). For blends, use the gentlest method that the label allows.
2. Pre-treat stains gently. Use a tiny drop of mild detergent directly on the stain. Rub with your fingers or a soft cloth, working from the outside in. Do not scrub hard, as that can felt or pill the fibers.
3. Fill a basin with cool water. Use water that’s cool or lukewarm (below 30°C / 86°F). Hot water shrinks wool and can set wrinkles in cotton or acrylic. Add the recommended amount of detergent and swish to distribute.
4. Submerge the cardigan. Gently press it into the water. Let it soak for 10–15 minutes. Do not rub, wring, or twist. If the cardigan is heavily soiled, you can gently squeeze the water through the fabric, but avoid any aggressive motion.
5. Rinse in clean water. Drain the soapy water and refill with cool water. Press the cardigan to release suds, then lift it out. Repeat until the water runs clear. For wool, you can add a splash of white vinegar to the final rinse to help remove soap residue (it rinses away and doesn’t leave a smell).
6. Remove excess water without wringing. Lay the cardigan flat on a clean, dry towel. Roll the towel up with the cardigan inside, pressing gently as you roll. This absorbs most of the water. Unroll and lift the cardigan—do not pull or stretch it.
7. Dry flat on a rack or towel. Place the cardigan on a flat drying rack or a fresh dry towel. Shape it gently with your hands to its original dimensions—do not pull the hem or sleeves. Let it air dry away from direct sunlight and heat sources. Flip it over halfway through drying if needed.
8. Once dry, remove pills (if any). Use a fabric shaver or a sweater comb to gently remove any pills. Work in one direction, using light pressure. Do this only on dry fabric.
9. Fold for storage. Lay the cardigan flat on a clean surface. Fold the sleeves inward so they lie across the body. Then fold the cardigan in half lengthwise, and then in half again (or thirds, depending on drawer depth). Place it in a drawer or on a shelf. Do not hang a knit cardigan—hanging stretches the shoulders and can create a “batwing� shape.
10. If you must hang it, use a padded hanger. Fold the cardigan over the hanger’s bar so the weight is distributed evenly, rather than putting the hanger through the shoulders. This reduces stretching.

Common Mistakes

• Using hot water. Hot water shrinks wool and can distort acrylic or cotton blends. Always use cool or lukewarm water.
• Wringing or twisting. This stretches the fibers and can cause permanent misshaping. Always roll in a towel to remove water.
• Hanging a wet cardigan. The weight of the water pulls the cardigan down, stretching it out. Always dry flat.
• Using regular detergent. Standard detergents contain enzymes that can break down wool fibers. Use a mild or wool-specific detergent.
• Storing on a hanger. Even dry, the weight of the cardigan can stretch the shoulders over time. Fold it instead.
• Rubbing stains. Scrubbing a stain can felt the fibers and cause pilling. Blot or gently press instead.

Tips

• Wash less often. Cardigans don’t need washing after every wear. Air them out between wears, and spot clean small marks. This reduces wear and pilling.
• Use a mesh bag for machine washing. If the label allows machine washing, put the cardigan in a mesh bag and use the delicate cycle with cold water. Still dry flat—never put knitwear in the dryer.
• Add a bit of hair conditioner to the rinse. For wool or cashmere, a small amount of conditioner (about a teaspoon) can soften fibers. Rinse thoroughly afterward.
• Store with cedar or lavender. These natural moth repellents are safer than chemical balls and smell nicer.
• Rotate your cardigans. Don’t wear the same one every day. Giving them a rest day lets the fibers recover their shape.
• Use a sweater stone. A pumice-like stone can gently lift pills without damaging the fabric, more so than a razor.

Troubleshooting

• Cardigan stretched out after washing. If it’s still damp, you can gently reshape it while it dries. If it’s already dry, you can often shrink it back slightly by soaking in lukewarm water for 10 minutes, then drying flat while gently compressing the fabric. For wool, this usually works; for cotton, it may not.
• Pills appear after washing. Remove them with a fabric shaver or sweater comb. To prevent future pilling, turn the cardigan inside out before washing and avoid rubbing against rough surfaces.
• Cardigan smells musty. This often happens if it wasn’t fully dry before storing. Wash again, dry completely, and ensure your storage area is dry. Add a sachet of baking soda in the drawer to absorb moisture.
• Color bled or faded. If a bright cardigan bled onto other clothes, wash it separately next time. To prevent fading, always use cold water and turn the cardigan inside out when washing.
• Cardigan shrank. For wool, you can try soaking in lukewarm water with a little hair conditioner, then gently stretch it back to shape while damp. Do not pull too hard—work gradually. This may not fully restore it, but it can help.

Frequently Asked Questions

Can I machine wash a cardigan?

Yes, if the care label says it’s safe. Use a mesh bag, cold water, and the delicate cycle. Never put it in the dryer—always dry flat.

How often should I wash a cardigan?

Only when it’s visibly dirty or smells. Most cardigans can be worn 3–5 times before washing, especially if you wear a shirt underneath. Over-washing causes pilling and fading.

Is it okay to dry a cardigan in the sun?

No. Direct sunlight can fade colors and make fibers brittle. Dry in a shaded, well-ventilated area.

Can I iron a cardigan?

Most knit cardigans should not be ironed directly. If you must, use a low heat setting and place a cloth between the iron and the cardigan. Better yet, use a steamer to remove wrinkles.

How do I remove pilling without damaging the fabric?

Use a fabric shaver or a sweater comb. Work gently in one direction, and avoid pressing too hard. For delicate fibers like cashmere, use a pumice stone designed for sweaters.

My cardigan lost its shape—is it ruined?

Not necessarily. If it’s wool or cashmere, you can often reshape it by soaking in lukewarm water, then gently stretching and pinning it to the right dimensions while drying flat. Cotton or acrylic may be harder to fix, but you can try the same method.
