For most white clothes, an oxygen-based stain remover or whitening powder is the best all-rounder: it lifts tea, coffee, wine and sweat marks and brightens greying fabric without chlorine. Pair it with a biological washing powder, because independent testing by Which? found biological detergents better at stain removal and powders better than liquids and capsules at keeping whites bright. Use a spray or gel pre-treater for specific marks, and keep chlorine bleach for plain cotton and linen only.
White school shirts, sports kit and bedding show every mark, and the stain remover aisle is full of products that promise to fix all of them. In reality, different removers are built for different jobs. Matching the product to the stain is what makes whites come out bright. This guide is part of our main advice on fresh, clean laundry in the UK.
Types of Stain Remover Compared
| Type | Best for | Watch out for |
|---|---|---|
| Oxygen whitening powder (sodium percarbonate) | Soaking and boosting whole loads; tea, coffee, wine, fruit and general greying | Not for wool, silk or leather |
| Enzyme spray or gel | Protein and food stains: blood, egg, grass, sweat, baby food | Works best when given time before the wash |
| Solvent-based pre-treater | Grease, make-up, ink and biro | Test on a hidden seam; use with good ventilation |
| Chlorine bleach | Plain white cotton and linen only | Yellows polyester and stretch fabrics; can make sweat stains worse; never mix with other cleaners |
| Colour run remover | Whites stained by a stray coloured item | Use as soon as possible after the accident |
What Independent Testing Shows
Which?'s laundry detergent testing checks products against a long list of common stains. Two findings matter most for whites:
- Biological beats non-biological on stains. Detergents with enzymes were generally more effective at stain removal.
- Powder beats liquid for brightness. Powders consistently did better at stain removal and keeping whites bright, while liquids and capsules did better on colour care.
Which? has also tested dedicated fabric stain removers. In that earlier round, most of the products performed well, and two of the best cost under £3.50, so a higher price is no guarantee of better results.
Match the Remover to the Stain
| Stain on whites | Use | Tip |
|---|---|---|
| Tea, coffee, red wine, fruit juice | Oxygen whitener soak | Rinse with cold water as soon as possible |
| Blood, egg, grass, sweat | Enzyme pre-treater, then biological detergent | Cold water first; heat can set proteins |
| Grease, butter, make-up | Washing-up liquid or a solvent pre-treater | Treat before washing, then wash warm |
| Ink and biro | Solvent-based pre-treater | Dab from behind onto kitchen roll |
| General greying | Oxygen whitener with a biological powder | Wash whites separately and do not overdose |
| Yellow underarms and collars | Enzyme pre-treat plus oxygen soak | Avoid chlorine bleach on sweat stains |
Yellowing is a problem of its own, built up from sweat, deodorant and body oils. Our guide to removing yellow stains from white clothes walks through it in detail.
Why Whites Go Grey in the First Place
Dye Transfer
A single coloured item in a white load can tint everything slightly. Wash whites on their own.
Too Much Detergent
Residue that does not rinse out traps dirt and dulls fabric over time.
Hard Water
Minerals settle in fibres and reduce how well detergent works.
Always Washing Cool
Whites benefit from a 40°C wash, with an occasional 60°C where the label allows.
Safety and Fabric Care
Check the Label and Never Mix Products
Many school shirts and sports tops are polyester blends, which chlorine bleach can turn yellow. Oxygen whiteners suit most cotton and polyester whites but not wool, silk or leather. Never combine chlorine bleach with other stain removers or acidic cleaners, and keep all laundry products in their original containers, away from children.

Shop Laundry CareFrequently Asked Questions
Is oxygen bleach better than chlorine bleach for whites?
For most households, yes. Oxygen bleach lifts stains and brightens whites without the yellowing chlorine can cause on polyester and stretch fabrics, and it is gentler on fibres.
How do I get school shirts white again?
Soak them in an oxygen whitener for a few hours, pre-treat collars and cuffs, then wash at 40°C with a biological powder. Wash whites separately and avoid overdosing detergent.
Do stain removers work at 30°C?
Many are designed for cool washes, especially enzyme pre-treaters. Giving the product time on the stain before washing matters more than the temperature.
Can I use a whites stain remover on colours?
Only if the pack says it is colour-safe. Some whitening products contain optical brighteners or bleaching agents that can fade colours.
