A leaked biro or spilt ink looks alarming, but alcohol is its weak spot — surgical spirit dissolves most ballpoint and many inks. The key is to dab and lift, never rub, so you don't spread it into a bigger mark.
Lay a clean cloth under and over and blot — don't rub. Rubbing turns a small ink spot into a large grey smear.
- Clean white cloths
- Surgical spirit (rubbing alcohol)
- Washing-up liquid
- Cool water
- Cotton wool
Step by step (carpet)
- Test first by dabbing surgical spirit on a hidden patch.
- Dab the ink with cotton wool lightly dampened in surgical spirit, lifting colour onto a clean piece each time. Surgical spirit is flammable — open a window and keep it away from naked flames.
- Work slowly from the outside in — patience stops it spreading.
- Wash the residue with a little washing-up liquid in cool water; blot.
- Rinse with clean water and press dry.
An old trick is alcohol-based hairspray instead of surgical spirit — it can work, but modern hairsprays vary, so plain surgical spirit is more reliable. Either way, test first.
By surface
🛋️ Sofas & upholstery
Check the cushion's cleaning code first: W or W/S means the method above is fine used sparingly; S means solvent-clean only, so leave that to a professional. Use less water than on carpet and blot, don't soak.
🧶 Wool & delicate rugs
Alcohol-based treatments that work on carpet can strip the colour from a dyed rug along with the ink, so on anything wool or hand-made, take extra care. Use cool water and a gentle touch — wool can ‘brown’ if over-wet and some rug dyes run. Test a hidden corner first, and for an antique, hand-knotted or silk rug, don't gamble — leave it to us.
🛏️ Mattresses
Ink spreads the moment it's wetted, so on a mattress dab around the edge of the mark and work inwards — and accept that biro on bedding fabric often leaves a shadow. You can't rinse a mattress, so go light: blot, treat sparingly, then use bicarbonate of soda to absorb the rest. Never soak it — trapped moisture leads to mould and smells.
✅ Do
- Test the solvent on a hidden patch
- Dab and lift, never rub
- Swap to clean cotton wool often
- Work from the outside in
🚫 Don't
- Rub — it spreads the ink
- Soak solvent into the backing
- Use bleach
- Over-wet the area

Does hairspray really remove biro from carpet?
It used to work more often, because older hairsprays were mostly alcohol — which is exactly what dissolves ballpoint ink. Modern formulas vary, and many add sticky resins that leave a residue of their own, so plain surgical spirit is the more reliable choice. Whichever you use, test a hidden patch first and dab rather than rub.
Will a hired carpet cleaning machine get ink out?
Usually not on its own. Hire machines rinse with a water-based solution, and ballpoint ink doesn't dissolve in water — so the machine can spread the mark and over-wet the carpet without actually shifting the ink. A solvent treatment has to come first; there's more in our guide to why hiring a carpet machine costs more.
Can old ink stains be removed from carpet?
Often improved, not always erased — ink that's had time to set can leave a faint shadow even after careful treatment. Professional hot-water extraction can usually draw out more than home methods, and we'll tell you honestly beforehand what we expect to lift. WhatsApp us a photo of the stain for a free assessment.
