Accidents Happen! A Guide to Wool Mishaps (and How to Fix Them)
Wool is tougher than it looks — but stains, shrinkage, and the occasional moth still happen to the best of us. Here’s how to handle the most common mishaps, no panic required.
Stains
Act fast, but gently — most wool stains come out fine if you don’t make them worse first.
- Blot, don’t rub. Rubbing pushes the stain deeper into the fibres and can cause felting on the spot.
- Start with cold water only. Warm or hot water can set certain stains (and risks shrinkage — see below).
- Use a wool-specific detergent or a small amount of mild soap, worked in gently with your fingers, then rinse with cold water.
- For oil-based stains (butter, makeup): sprinkle with talcum powder or cornstarch, leave for a few hours to absorb the oil, then brush off before washing as usual.
- For anything set-in or stubborn, a professional wool/textile cleaner is worth it — some stains genuinely need expert treatment, and that’s fine.
Help — my wool shrank!
Shrinkage happens when heat and friction cause wool fibres to “felt” — the microscopic scales on each fibre lock together and pull tight. It’s the reason our care instructions are so insistent about cold water and no tumble drying.
If it’s already happened, here’s a rescue attempt (works best on mild shrinkage, not full felting):
- Soak the item in lukewarm water with a capful of hair conditioner or wool wash for about 15–20 minutes — this relaxes the fibres.
- While still wet, gently stretch the item back towards its original size and shape, a little at a time.
- Lay flat on a towel, pin the edges to roughly the right dimensions if needed, and let it air dry completely without moving it.
Honesty first: this works for mild shrinkage, not for wool that’s fully felted (stiff, dense, almost fabric-like). Once fibres have completely locked together, the change is usually permanent — which is exactly why prevention (cold water, gentle cycle, lay flat) matters so much. See our Wool Care Guide.
What actually happens if I wash wool in hot water?
Heat opens the microscopic scales on wool fibres. Combined with the agitation of a wash cycle, those open scales interlock with each other — that’s felting. The result: shrinkage, a stiffer, denser texture, and a loss of the softness that made you fall in love with the piece in the first place.
A single accidental warm wash isn’t necessarily catastrophic — try the rescue method above. A full hot wash and tumble dry, though, is the fastest way to turn a beanie into a coaster.
Moths: protecting your wool
It’s not the adult moths that damage wool — it’s their larvae, which feed on keratin, the protein wool is made of. And let us share the bad news — they always go for the very piece that you love the most.
Prevention:
- Cedar blocks or rings and lavender sachets are natural deterrents — moths dislike the scent. Refresh (lightly sand cedar, replace lavender) every few months as the scent fades.
- Store clean items only. Body oils, food residue, and even invisible skin cells attract moths — always wash or air out a piece fully before storing it (see Time to Rest!).
- Keep wool moving. Moths prefer undisturbed, dark spaces. Items worn and aired regularly are much less at risk than those left untouched for months.
- For long-term storage of pieces you won’t touch for a while, breathable garment bags with a moth deterrent inside offer good protection without trapping moisture.
If you find damage (small irregular holes, fine webbing, or tiny casings):
- Isolate the item immediately — seal it in a plastic bag to stop any larvae spreading to other pieces.
- Freeze it for 48 hours (in the sealed bag) — this kills both larvae and eggs.
- Wash as usual afterwards, and give your storage area a thorough vacuum and wipe-down before putting anything back.
Other small wool mishaps
- Pilling (little fabric bobbles): gently remove with a fabric comb or pill-remover, working in one direction. Don’t rub or pick with your fingers — that can pull the knit.
- Snags or pulled threads: never cut them. Use a needle to gently ease the loose thread back through to the inside of the garment.
- Static: a light mist of water, a fabric-safe anti-static spray, or simply a few seconds of steam usually settles it.
- Colour fading or bleeding: wash similar colours together, always in cold water with a wool-specific detergent, and turn darker pieces inside out.

Frequently Asked Questions
Can I remove a stain from a wool item?
Yes, in most cases – blot (don’t rub) with cold water and a wool-specific detergent. See our full guide, Accidents Happen!, for stain-specific tips.
Help — my wool shrank. Can I fix it?
Sometimes, if the shrinkage is mild. Soak in lukewarm water with a little hair conditioner, then gently stretch it back into shape while damp and dry flat. See Accidents Happen! for the full method – and why prevention is easier than the fix.
What happens if I wash wool in hot water?
Heat and agitation cause wool fibres to “felt” – shrinking and stiffening permanently in most cases. Always wash wool in cold water. Full explanation in Accidents Happen!
How do I protect my wool from moths?
Store clean items only, use cedar or lavender as a natural deterrent, and keep pieces moving rather than untouched for months. Full prevention and treatment tips in Accidents Happen!
