Remove Pilling from Sweaters and Restore Them to Wearable Condition
Pilling happens to the best of us—and the best sweaters. Here's how to restore your knits to their original smooth finish using tools you likely already own.
5 min read · IrisPilling is the small, fuzzy balls that form on the surface of sweaters and knits after wear or washing. It's not a sign of poor quality—even luxury cashmere pills. It happens when short fibers work loose from the yarn and tangle together into little bobbles. The good news: it's purely cosmetic and entirely reversible.
You don't need to buy expensive de-pilling tools or specialty products. Most effective methods use items already in your home: a razor blade, a fine-tooth comb, or even a pumice stone. Each technique works slightly differently depending on your sweater's fiber content and the severity of the pilling.

What you'll need.

- 02Electric fabric shaver or de-pilling machine
- 03Clean single-edge razor blade (optional)
- 04Soft brush or lint roller
Step one · 2 minutes
Lay your sweater flat on a clean surface
Spread the garment on a bed, table, or ironing board with good lighting. Smooth out any wrinkles and stretch the fabric gently so you can see the pilled areas clearly. Work on one section at a time—the sleeves, front, back, and cuffs may pill at different rates. This prevents you from missing spots and ensures even treatment across the garment.
Natural daylight or a bright lamp helps you spot smaller pills you might miss otherwise.
Step two · 3 minutes
Use a fine-tooth comb for gentle removal
Hold the sweater taut with one hand and gently comb the pilled area in one direction using short, light strokes. A fine-tooth comb (like a flea comb or lice comb) works best. The teeth catch the pills and pull them away from the fabric surface. This method is safest for delicate fibers like cashmere, merino, or silk blends because it doesn't cut the yarn.
Comb in the direction of the nap if your sweater has one. Stop if you feel resistance—don't force the comb through.

Try a fabric shaver for stubborn pilling
Electric fabric shavers (also called de-pilling machines) are designed specifically for this task and are widely available for under $15. Hold the shaver flat against the sweater and move it gently across the pilled area in slow, overlapping passes. The rotating blade cuts the pills away without harming intact fibers. This works quickly on heavier knits like wool and cotton blends.
Never press hard or hold the shaver in one spot. Let the tool do the work. Stop if you notice snags or pulls in the fabric.
Step four · 1 minute
Use a clean razor blade for precision
For small, localized pilling, a single-edge razor blade works in a pinch. Hold the sweater taut and gently scrape the pilled area with the blade held at a shallow angle—almost flat against the fabric. Use light pressure and short strokes. This method requires a steady hand and works best on sturdy knits. Avoid this technique on delicate or loosely-knit fabrics.
Test on an inconspicuous area first. Never use a dull blade, which can snag fibers instead of cutting them cleanly.
Step five · 1 minute
Brush away loose fibers and inspect
After removing pills with any method, use a soft brush or lint roller to sweep away the loose fibers. This prevents them from re-adhering to the sweater. Hold the sweater up to the light and inspect the treated area. The surface should feel smooth and look uniform. If you see remaining pills, repeat the process on those spots.
A soft clothes brush or even a clean toothbrush works well for this final step.
How to know it worked
Run your hand across the sweater. The surface should feel smooth and consistent, without the bumpy texture of pills. The fabric should look uniform under good lighting, and you shouldn't see any loose fibers or snags. Your sweater is ready to wear.
Questions at the mirror.
Will removing pills damage my sweater?
No, if you use the right technique. Pills form on the surface from loose fibers—they're not part of the sweater's structure. Gentle combing or a fabric shaver removes only the pills, not the intact yarn. Avoid aggressive scrubbing or pressing hard with a razor, which can thin the fabric.
Can I prevent pilling in the future?
Partially. Pilling is natural wear, but you can slow it down: wash sweaters inside-out in cold water, use a gentle cycle, avoid fabric softener, and lay flat to dry. Store sweaters folded rather than hanging to reduce friction. Looser knits and higher-quality fibers pill less than cheap, tightly-woven synthetics.
What if my sweater pills immediately after washing?
This usually means the yarn quality is lower or the knit is very loose. Remove the pills as described here, then consider whether the sweater is worth keeping. Frequent re-pilling on a new garment suggests poor construction, not improper care.
Is a fabric shaver worth buying?
If you own multiple sweaters or knits, yes. A basic electric de-piller costs $10–20 and lasts years. It's faster and safer than razors for regular maintenance. If you own only one or two sweaters, a fine-tooth comb works just as well.
