How to treat yellow sweat marks
Use the pink one: Enzyme PoweredOld yellowing that has been through many washes may need a second treatment. Repeat the spray, wait and wash rather than leaving it on longer.
- 1Spray directlySpray Enzyme Powered onto the stain until it's wet through. Don't rub: it pushes the stain deeper.
- 2Wait 1–3 minutesLeave it to work. Don't let it dry on the fabric; if it starts to, mist it again.
- 3Wash as normalWash with your usual detergent, following the care label. Check the stain has gone before tumble drying.
How to treat oily yellowing on collars, cuffs and necklines

- 2Wait 1–3 minutesLeave it to work. Don't let it dry on the fabric.
- 3Wash as normalWash with your usual detergent, following the care label. Air-dry first and check: heat can set any oily residue.
Why whites go yellow in the drawer
A white top that was put away clean-looking can come out yellow months later. Traces of sweat, body oil or skincare that the last wash didn't remove change colour over time. Treat any marks and wash whites before you store them for the season, and make sure they're completely dry.
Chlorine bleach isn't the answer for yellow underarm or collar marks: it doesn't break down sweat or body oils, and on a curry or turmeric spot it can turn the mark orange. Treat the stain with the right spray first.
Top tips
- Treat underarms and collars every few washes, not only when the yellow is obvious.
- Let deodorant dry fully before you get dressed.
- Air-dry treated whites and check them in daylight before using a dryer.
