How to remove old and set-in stains

A stain sets when it has been through a hot wash, the tumble dryer or an iron, or simply left for a long time. It's harder work than a fresh mark, but often not a lost cause. The trick is to work out what the stain was, use the matching bottle, and repeat rather than soak.

  • Not sure?

    Think about where it is: food on the front of a top, grime on a collar, sweat under the arms.

The method for old stains

  1. 1Saturate the stainSpray the matching bottle until the stain is wet through. Don't rub.
  2. 2Wait the full 1–3 minutesGive it the full time. Don't let it dry on the fabric.
  3. 3Wash, then checkWash as normal, following the care label. Air-dry and look at the stain in daylight.
  4. 4Repeat if neededIf the mark is lighter but still there, treat and wash it again. A second pass works better than leaving the spray on longer.

Why heat matters

Heat from a dryer or iron fixes stain residue into the fibres, which is why set-in stains are so stubborn. Until you're sure a stain has gone, air-dry the garment and don't iron over the mark.

Top tips

  • Look at the stain in daylight after washing. It's easy to miss a faint mark under indoor lights.
  • On delicate or valuable clothes, test on a hidden area first and follow the care label.
  • Treat one stain with one bottle. Don't layer both formulas on the same spot.

Questions

No. Dried-in marks often need a second pass. Re-spray, leave for the full 1–3 minutes and wash again rather than extending the working time on a single application.

Heat sets stains, which makes them harder to shift. Treat it with the matching bottle and wash again; stubborn marks may need more than one round.
