Pilling
Also: bobbling · fuzzballs
Pilling is the small balls of tangled fibers that form on a fabric's surface where it rubs against itself or other surfaces — common on knits, under the arms, and at the cuffs. It's one of the most frequent signs of wear on used clothing and a key input to the fabric-condition grade.
How to get pills off a garment
- 1Lay the garment flat on a hard surface. Doing this on your lap stretches the knit, the fabric lifts into the blade, and the shaver cuts it.
- 2Work out how loose the knit is first. If you can see daylight between the stitches, or the fiber is cashmere, mohair or angora, use a comb rather than a blade.
- 3Go over the pilled area with a fabric shaver on its lowest setting, holding it flat and letting its own weight do the work. Pressing down is what makes a hole.
- 4Work in one direction, in short strokes, and empty the shaver often. A full chamber stops cutting and starts pressing pills back into the fabric.
- 5Stop when the surface reads smooth from a low angle. Chasing the last few pills is how people shave a hole in a sleeve, and the last few are not the ones anybody notices.
- 6Look at what is underneath. Pills are fiber that has already left the yarn, so a patch that reads thin or shiny after shaving was thin before you started. That is fabric thinning, not pilling, and it does not come back.
Stopping it happening again
Pilling is abrasion, so it comes from friction rather than dirt, and washing more often makes it worse rather than better. Turn knitwear inside out, use a mesh bag, wash cold on a gentle cycle and skip the dryer, where the tumbling does in one cycle what a week of wear does. Wash synthetics separately from cotton, because a polyester pill is anchored by a fiber stronger than the yarn around it and rubbing the two together is what forms them. The underarm and the side you carry a bag on will always go first, whatever you do.
Which tool, and what each one costs you
Ranked, with the damage each one does when it goes wrong. Every method here works on something; the question is whether it works on yours.
| Method | Verdict | What it is good at | How it goes wrong |
|---|---|---|---|
| Electric fabric shaverAbout $15 to $25 | Best | Fastest on a firmly knitted jumper, a fleece or a sweatshirt, and the only method that stays even across a large area. | Cuts a hole in seconds on a loose knit or over a seam, and the damage is not repairable. Lowest setting, no downward pressure, and never over a raised seam. |
| Sweater comb or stoneAbout $8 to $15 | Good | The right tool for cashmere, mohair, angora and anything loosely knitted, because it catches the pill without a blade near the yarn. | Slow, and it drags a delicate knit out of shape if you pull rather than sweep. Support the fabric with your other hand. |
| Disposable razorYou already own one | It depends | Genuinely fine on a flat, firmly woven surface when you have one jumper and no shaver, which is why every article recommends it. | The reason every article should qualify it: a razor has no guard and no depth stop, so it removes pills and good yarn at the same rate. Use a blunt blade, hold it almost flat, and never on a loose knit. |
| Pumice stoneA few dollars | It depends | Good on heavy cotton and fleece, where it lifts pills without cutting anything. | Abrades the surface it is dragged across, so it dulls a dark color over repeated use and is wrong for anything fine. |
| Sticky tape or a lint rollerYou already own one | Avoid | Nothing, for this. It lifts loose fluff sitting on the surface. | No damage, but no result either. A pill is anchored by fibers still attached to the yarn, which is the whole difference between a pill and lint. |
| ScissorsFree | Avoid | Snipping individual pills is precise on the two or three you can see. | It is also how a small hole starts, because a pill sits directly on the yarn holding it. On a knit, one cut stitch runs. |
How much pilling is too much
What each amount is worth on the 1.0 to 10.0 scale, and whether it is worth your afternoon.
None to trace
Surface reads smooth from a low angle. A few pills at one cuff at most.
Grade: No effect. Excellent (8) and above is still available.
What to do: Nothing. Do not shave a garment that does not need it.
Light
Visible pills in the friction zones only: underarms, inner thighs, the side you carry a bag on.
Grade: Nudges Fabric Condition down. Typically Excellent (8) toward Good (6.5 to 7).
What to do: Worth de-pilling. This is the band where twenty minutes of work moves the grade.
Moderate
Pills across whole panels rather than just the friction zones, and the surface has lost its finish.
Grade: Good (6) toward Fair (5).
What to do: De-pill and then look again. Some of this comes back to light; some of it turns out to be thinning.
Heavy
The whole garment reads dull and matted. Pills come away in the hand.
Grade: Fair (5) or below, and de-pilling will not recover it.
What to do: The yarn is already gone. Shaving reveals thinning rather than fixing it, so disclose and price accordingly.
The bands are the grading rubric, not a rule of thumb. How the 1.0 to 10.0 scale works.
What changes by fabric
The method above is the general one. These fabrics need a different approach.
- Pilling on synthetics
synthetics — A synthetic pill is anchored by a fiber stronger than the yarn around it, so shaving removes the pill and leaves the anchor to make another.
- De-pilling wool and cashmere
wool and cashmere — Wool pills are dead fiber that has already left the yarn, so unlike synthetics they come away for good.
How to spot it
- Look at high-friction zones: underarms, inner thighs, cuffs, and collar
- Angle the garment under light — pills cast tiny shadows
- Run a hand across the surface; pilled fabric feels rough, not smooth
Grade impact
Pilling drives the Fabric Condition factor (30% of the grade). Light, sparse pilling nudges an item from Excellent (8) toward Good (6); heavy, widespread pilling that dulls the whole surface pushes it into Fair (5) or lower.
Fixability
Often improvable: a fabric shaver or sweater comb removes surface pills, though it can't restore fibers already thinned by abrasion. De-pilling before photographing can legitimately raise the grade.
How to disclose it
Note it plainly ('light pilling at the cuffs') and show a close-up. Disclosed pilling rarely causes a return; undisclosed pilling in a 'like new' listing does.
Pilling — frequently asked
- Does pilling lower a clothing grade?
- Yes. Pilling is assessed under the Fabric Condition factor, which is 30% of the overall grade. Light pilling in the friction zones drops an item a tier or so; pilling across whole panels takes it toward Fair (5) or below. De-pilling before grading can legitimately raise the result, because the grade is of the garment in front of the camera.
- Why do clothes pill in the first place?
- Friction, not dirt. Every rub breaks a few fibers loose from the yarn; they stay attached at one end and tangle with each other into a ball. That is why it appears at the underarm, the inner thigh and wherever a bag strap sits, and why a garment that is never worn never pills however long it hangs there.
- Do some fabrics pill more than others?
- Yes, and the reason is counter-intuitive. Pilling starts on almost everything; what differs is whether the pill falls off. Short-staple natural fibers shed their pills, so cotton and wool look better than they are. Synthetics do not: a polyester or nylon fiber is stronger than the yarn holding it, so the pill stays put and accumulates. Blends are the worst of both, which is why a 50/50 sweatshirt pills more visibly than either fiber alone.
- Will removing pills damage the garment?
- It can, and the two ways it happens are avoidable. Cutting a hole comes from pressing down, working over a seam, or using a blade on a loose knit; hold the tool flat, let its weight do the work and use a comb on anything you can see daylight through. The subtler one is that shaving does not put fiber back, so a patch that has pilled and been shaved repeatedly gets genuinely thin. At that point you are managing thinning, not pilling.
- Can you stop clothes pilling permanently?
- No, because the cause is wear. You can slow it a lot: inside out, mesh bag, cold gentle cycle, no dryer, and synthetics washed apart from cotton. What you cannot do is stop a jumper you wear weekly from pilling at the underarm, and a garment sold as never pilling is either unworn or made of something that sheds its pills rather than never forming them.
- Should I de-pill a garment before selling it?
- Usually yes, for the light and moderate bands, because a smooth surface photographs honestly and the grade is of what the buyer receives. Two caveats. Do not shave a heavily pilled garment expecting it to come back; you will expose thinning and have less to sell. And do not shave it and then describe it as never pilled, because it will pill again in the same places and that is the return.
What if it does not all come out?
Most of the time some of it stays, and the leftover is what a buyer sees. A garment is worth what its condition says it is worth, so the sensible next question is how much this particular flaw moves the number.
