How to Remove Pills From a Cardigan Without Damage

Removing pills can make a cardigan look smoother and fresher, but pulling them off by hand may loosen or break the knit. Work slowly on a clean, dry garment, choose a tool suited to the yarn, and test an inconspicuous area first.

What You’ll Need

A clean, flat surface with good light
A fabric shaver or sweater comb; use one tool at a time
A lint roller or soft clothes brush for loose fibres
A clean towel, if you need to support a delicate or loosely knit area

A fabric shaver is usually easiest on sturdy, smooth knits. A sweater comb can offer more control on delicate yarn, but requires a very light touch. Check the garment’s care label and the tool instructions before starting. Avoid using scissors or a disposable razor as your first choice: both can cut yarn if they catch a loop.

Step-by-Step

Check the care label and identify the knit. Look for washing and handling instructions, and note whether the cardigan is fine, fuzzy, open, or loosely knit. If the label says to dry-clean only, or the garment is particularly valuable or fragile, ask a professional cleaner to remove the pills. Do not use a shaver on fluffy fibres such as brushed mohair or on openwork where the tool may catch the knit.
Make sure the cardigan is clean and completely dry. Dirt and damp fibres can make pills harder to remove and increase the chance of snagging. If it needs washing, follow the label and let it dry fully before depilling. Do not stretch or pull a wet cardigan flat.
Lay it flat without stretching it. Use a clean table or other firm, smooth surface. Smooth the panel gently with your hand so it lies evenly; do not pull the fabric taut. For a thin area, place a clean towel underneath for support. Keep sleeves and other layers out of the way so you treat one section at a time.
Test your tool in a hidden spot. Try a small patch on the inside of a hem or another inconspicuous area. With a fabric shaver, turn it on and glide it lightly over the surface without pressing down. With a sweater comb, make one or two short, gentle strokes in the direction of the knit. Stop and inspect the test area for pulled loops, thinning, or a fuzzy bare patch. If you see any, do not continue with that tool.
Remove pills in small sections. If the test is safe, work across a small area at a time. Keep a shaver’s head flat against the fabric and move it slowly in short passes; do not bear down or linger in one spot. Keep the fabric level but relaxed. For a comb, hold the fabric steady and draw the comb lightly across the pill-covered surface, following the knit’s direction. Lift the tool between strokes rather than scraping back and forth.
Protect edges, seams, and details. Avoid buttons, buttonholes, zippers, embroidery, cuffs, and seams with a powered shaver. Work close to these areas only if you can clearly see the yarn and control the tool; otherwise, leave the pills or ask a cleaner for help. Never run a tool over a loose loop. Stop and gently settle a snag with a blunt knitting needle or crochet hook rather than cutting it.
Clear the removed fibres and inspect your work. Switch off and empty a fabric shaver as its instructions direct. Use a lint roller or soft brush to collect remaining clippings. Check the panel in good light from different angles. Treat only pills that remain; repeated passes on already smooth fabric can thin or roughen the surface.
Finish with careful storage and washing habits. Fold the cardigan rather than hanging it if its weight could stretch the shoulders. Wash it as the label directs, preferably with similar soft garments and with friction kept to a minimum. Pilling may return through wear; remove new pills in short, gentle sessions rather than waiting until they form a dense layer.

Common Mistakes

Pulling pills off by hand: Pills are often attached to the knit. Tugging can draw out yarn, create a run, or leave a weak spot.
Pressing too hard: A shaver should cut the raised pills, not shave the fabric itself. Pressure can flatten or damage the knit.
Working on stretched fabric: Pulling a panel taut can expose yarn to a blade and distort the garment. Keep it flat but relaxed.
Using a razor or scissors carelessly: These can cut a strand or slice a loop. If using scissors for one clearly detached pill, keep the blades away from the fabric and snip only the pill; do not trim close to the surface.
Depilling fuzzy or open knits with a shaver: Long fibres and large gaps can catch in the cutting head. A tool unsuitable for the texture may cause more damage than the pills.
Repeating passes until the surface looks perfectly smooth: Some texture is part of the yarn. Stop once raised pills are gone; do not remove sound fibres to make the knit look unnaturally bare.

Tips

Use bright, even light so you can see the yarn, pills, and any loose loops clearly.
Empty the shaver’s lint compartment when it fills; a clogged tool may work poorly. Follow the tool’s instructions when cleaning it.
For delicate yarn, use a comb only if its maker recommends it for that knit, and use almost no pressure.
Reduce future friction by washing the cardigan according to its label, avoiding rough items in the same wash, and storing it folded.
Keep a small repair kit nearby. A loop that has been pulled out should be eased back into the knit, not cut off.

Troubleshooting

The shaver catches or pulls the fabric: Switch it off immediately and lift it away without tugging. Check that the fabric is flat, dry, and supported, and that the shaver is clean and assembled correctly. Try a gentler tool only after testing another hidden area. If a loop has been pulled, do not cut it; ease it back with a blunt needle or crochet hook. If you cannot do that without stretching the knit, consult a knitwear repairer.

Pills remain after a pass: Do not press harder. Check whether the tool is designed for the garment’s knit and whether its head is clogged. Remove loose clippings, reposition the panel, and make one light pass. Some pills are close to the yarn and cannot be removed safely; leave them rather than risk cutting the knit.

The fabric looks fuzzy or thinned: Stop depilling that area. Further shaving or combing may worsen the damage. Brush away loose fibres gently and assess the garment after it rests flat. A cleaner or repairer can advise whether the area can be repaired.

The cardigan still looks uneven: Check it in natural or bright neutral light. Pilling can vary by panel because some areas rub more than others. Treat only obvious raised pills and avoid trying to make every part of the knit identical.

Frequently Asked Questions

Can I use a fabric shaver on every cardigan?
No. It is generally better suited to stable, smooth knits. Avoid it on open, very loose, brushed, or fragile yarn unless the garment and tool instructions specifically allow it.

Is a sweater comb safer than a fabric shaver?
Not automatically. A comb gives you manual control, but pressing or scraping too hard can still snag or abrade yarn. Test it first and use short, light strokes.

Should I remove pills before or after washing?
Work on a clean, completely dry cardigan. If it is dirty, wash it according to the care label and let it dry before depilling; washing can also loosen some pills for easier removal.

Can I cut pills off with scissors?
Only if a pill is clearly detached and you can snip it without touching the knit. For widespread pilling, a suitable comb or shaver is easier to control; never cut a loop or protruding yarn.

Why does my cardigan keep pilling?
Pilling forms when fibres rub together or against other surfaces. Areas under the arms, at the sides, or beneath bag straps may pill more. Gentle care can reduce friction, but it cannot guarantee that pilling will stop.

What should I do if I cut a thread?
Stop and do not pull the cut ends. A small snag or break may be repairable, but further handling can unravel the knit. Have a knitwear repairer assess it, especially if the cut is near a seam or has begun to run.
