How to Wash and Store a Pull or Sweat Without Shrinking or Pilling

Quick answer

Wash your pull or sweat inside out in cold water on a wool or delicate cycle with a gentle detergent, then dry it flat on a towel away from heat. Never hang a wet knit or tumble dry it, and store it folded rather than on a hanger. This routine prevents shrinking, pilling, and stretched shoulders.

A pull or sweat that fits well is worth protecting. Most knitwear damage happens in the wash and the wardrobe, not on your back, and the fixes are simple once you know what wool and cotton actually need.

This guide walks through the full routine: sorting, washing, drying, de-pilling, and storing. Follow it and your knitwear will keep its shape and softness through many seasons.

Before you wash: read the label and sort by fibre

Check the care label first. Wool, cashmere, and blends usually ask for cold hand washing or a wool cycle, while cotton and synthetics tolerate a gentle machine wash. If the label says dry clean only, respect it. Sorting by fibre and colour prevents dye transfer and friction between heavy and delicate knits.

Turn each piece inside out and close zips or buttons. This protects the outer surface from pilling and snags. If you are washing a wool pull, use a detergent made for wool; regular detergent can strip natural oils and make fibres feel rough.

• Wash similar colours and weights together; never mix a heavy sweat with a fine merino pull.
• Empty pockets and remove detachable belts or brooches before washing.

Washing: cold water, gentle cycle, no fabric softener

Use the coldest setting available, ideally 30°C or below. Heat is the main cause of shrinking in wool and cotton. Choose a wool or delicate cycle with a low spin speed, or hand wash if the label requires it. Add a small amount of gentle detergent and skip fabric softener, which coats fibres and reduces breathability.

If hand washing, support the garment with both hands and squeeze the water through rather than rubbing. Rubbing creates friction, and friction is what turns loose fibres into pills. Rinse in water of the same temperature to avoid thermal shock.

• Never wring or twist a wet knit; it distorts the stitches.
• For stains, dab with a tiny amount of detergent before washing instead of scrubbing.

Drying: flat, shaded, and patient

Lift the pull or sweat out of the machine or basin supporting its full weight. Lay it flat on a clean towel, reshape it to its original dimensions, and roll the towel to press out excess water. Then place it on a drying rack or a fresh towel in a shaded, ventilated spot.

Hanging a wet knit is the fastest way to stretch shoulders and lengthen the body. Direct sunlight and radiators can fade colour and make wool brittle. Expect 24 to 48 hours for a thick wool pull to dry completely.

• Turn the garment over halfway through drying so the underside dries evenly.
• If the label allows tumble drying, use the lowest heat and remove while slightly damp.

De-pilling: remove pills without pulling the knit

Pilling is normal on wool, cotton, and blends, especially under the arms and where a bag rubs. The goal is to remove the pills without tugging the surrounding fibres. A fabric shaver or a small sweater comb works well; use it on a flat surface with light pressure.

Work in one direction and empty the shaver frequently. Avoid pulling pills off with your fingers, which can loosen more fibres and create new pills. If the knit is very delicate, test the tool on an inside seam first.

• De-pill before washing, not after, so loose fibres do not tangle in the drum.
• For a quick refresh, use a lint roller on low-tack setting between washes.

Storing: fold, don't hang, and let wool breathe

Fold your pull and sweat and stack them on a shelf. Hangers stretch the shoulders and distort the neckline over time. If shelf space is tight, use a storage box lined with acid-free tissue or a clean cotton pillowcase. Avoid plastic bags, which trap moisture and can encourage mildew.

For seasonal storage, wash before putting away. Even invisible body oils can attract moths. Add cedar blocks or lavender sachets, and check the box every few months. A breathable cotton storage bag is a better choice than vacuum-sealed plastic for natural fibres.

• Store folded knits loosely; compressing them too tightly crushes the fibres.
• Keep storage in a cool, dry place away from direct sun.

Your step-by-step knitwear care routine

1. Step 1: Check the label and sort: Read the care label and separate wool, cotton, and blends. Turn garments inside out and close fastenings. Checkpoint: if the label says dry clean only, stop here and take it to a professional.
2. Step 2: Wash cold and gentle: Use a wool or delicate cycle at 30°C or below with gentle detergent. Hand wash if required, squeezing rather than rubbing. Common mistake: using hot water or fabric softener, which causes shrinking and dulls fibres.
3. Step 3: Dry flat in the shade: Press out water with a towel, reshape, and lay flat on a rack away from sun and radiators. Checkpoint: never hang a wet knit; it will stretch at the shoulders.
4. Step 4: De-pill lightly: Use a fabric shaver or sweater comb on a flat surface, working in one direction with light pressure. Common mistake: pulling pills by hand, which loosens more fibres.
5. Step 5: Store folded and breathable: Fold knits on a shelf or in a cotton bag with cedar or lavender. Avoid plastic and wire hangers. Checkpoint: wash before seasonal storage so oils do not attract moths.

Knitwear care in practice: a product example

• Plaid Sky - Bleu Sarah: Made in Portugal in 100% wool with a moss stitch and a flecked effect, available in Bleu Sarah, Havane, and Aubépine. Pure wool responds well to the cold, gentle routine above; treat it like your wool pull and avoid heat so the moss stitch keeps its texture.
• Coussin Mirage - Havane: Embroidered with cotton and wool in Havane, Terracotta, or Bleu Sarah, made in India, and offered in two dimensions. A mixed cotton-wool textile is a reminder to check fibre content before washing; if you ever launder a similar blend, use the wool setting and dry flat.

A little care in the wash and the wardrobe keeps a pull or sweat looking new. Cold water, flat drying, gentle de-pilling, and folded storage are the habits that matter most.
