Learn how to hand wash a cardigan, prevent sweater pilling, and dry it flat so it keeps its shape. A simple step-by-step knit care guide.
Quick answer
Hand wash your cardigan in cool water with a gentle detergent, then gently squeeze out water and dry it flat on a towel. Avoid wringing, hot water, and hanging, which cause shrinking and stretching. This method also reduces pilling by minimizing friction.
Why hand washing beats machine washing for cardigans
Machine washing agitates fibers, leading to shrinkage and pilling. Hand washing gives you control over water temperature and motion, which is especially important for wool, cashmere, and blends. Even if your cardigan is labeled machine washable, the delicate cycle can still cause damage over time.
Choosing the right detergent and water temperature
Use a gentle, pH-neutral detergent designed for delicates or wool. Harsh detergents strip natural oils, making fibers brittle and more prone to pilling. Always use cool or lukewarm water—hot water causes shrinkage and can set stains. If you're unsure, err on the side of cooler water.
How to dry a cardigan flat without stretching it
After washing, lay the cardigan on a clean, dry towel. Roll the towel with the cardigan inside to absorb excess water, then unroll and reshape the cardigan on a fresh dry towel. Let it air dry away from direct sunlight or heat. Hanging wet knits stretches them out of shape, so always dry flat.
Preventing pilling before it starts
Pilling happens when loose fibers rub against each other. To minimize it, turn your cardigan inside out before washing, avoid washing with rough fabrics like denim, and use a fabric shaver or sweater comb to remove existing pills gently. Store folded, not hung, to reduce friction.
Step-by-step cardigan washing
- Check the care label: Look for washing instructions. If it says dry clean only, hand washing may still be safe, but test a small area first. When in doubt, spot clean or dry clean.
- Pre-treat stains: Gently dab stains with a tiny amount of gentle detergent and cool water before washing. Don't rub, as it can cause pilling. Blot, don't scrub.
- Fill a basin with cool water: Add a capful of gentle detergent. Submerge the cardigan and gently squeeze the suds through the fabric for 2-3 minutes. Never twist or wring.
- Rinse thoroughly: Drain the soapy water and refill with cool water. Gently press the cardigan to release soap. Repeat until no suds remain. Soap residue attracts dirt and can cause stiffness.
- Remove excess water: Lift the cardigan carefully, supporting it with both hands. Lay it on a clean towel and roll the towel to absorb water. Do not wring. Wringing causes stretching and felting.
- Dry flat: Reshape the cardigan on a dry towel or mesh drying rack. Let it air dry completely away from heat or sunlight. Hanging wet knits leads to shoulder bumps and stretching.
- Store properly: Once dry, fold your cardigan and store it flat in a drawer. Avoid hanging to prevent distortion. Folding keeps the shape intact.
