Liquid laundry detergent stain test: Ariel Original vs Carrefour Expert and Epsil

Tomato splashes on a tablecloth, make-up on a shirt collar, or a biro mark inside a school bag: with every new wash, the same question comes up - which liquid laundry detergent actually removes stains properly, without hours spent scrubbing at the sink? A large comparison put eight widely used products head-to-head and identified clear standouts, including budget-friendly options.

How the big stain test was carried out

For this comparison, eight liquid laundry detergents commonly bought in France were put through a practical, real-world trial. Each detergent faced the same eleven everyday stains, applied to identical fabric and washed under comparable conditions. That way, it was easy to see which products did more than simply smell pleasant.

The stains tested included:

• Foundation and make-up
• Lipstick
• Biro ink
• Fruit such as berries
• Chocolate spread and dessert
• Coffee
• Red wine
• Cooking oil
• Meat sauce
• Tomato purée
• Soil and mud

All washes were done in a washing machine, using the temperature and dosage recommended by each manufacturer. There was no rubbing, no bile soap stick, and no pre-soaking - the detergent alone had to prove what it could do.

The clear winner: Ariel Original removes almost all stains

After all results were compared, one brand finished decisively on top: Ariel Original. It lifted nearly all of the stains in the trial by a clear margin, including especially stubborn marks such as tomato sauce, rich meat sauces and red fruits.

Ariel Original delivered a visibly brighter whiteness and made most difficult stains all but disappear - without any scrubbing beforehand.

Another advantage noted was how much whiter laundry looked after washing. So if you often deal with heavily soiled white towels, shirts or tablecloths, Ariel offers a very powerful option.

The downside: high cost and possible colour fading

That top-tier performance comes at a price. Calculated across a year, Ariel Original was the most expensive product in the test group, with average costs of around €63.27. In households running many loads each month, that can make a noticeable dent in the budget.

A second issue also emerged: testers observed that frequent washing with this detergent may gradually make colours look a little duller over time. For wardrobes full of colourful everyday clothing, the top performer is therefore not always the best choice as a long-term, routine solution.

Overall, Ariel Original is best suited to:

• very heavily soiled white laundry
• households where specific stain types keep coming up (e.g. children, enthusiastic home cooks)
• wash days when maximum stain power is needed for an occasional load

Two strong value picks: Carrefour Expert and Epsil

Carrefour Expert Optimal Clean: good results for much less

Close behind the winner was Carrefour Expert Optimal Clean. Its overall cleaning performance was rated as good: most day-to-day marks came out reliably, although very stubborn stains such as lipstick or biro were a bit harder to shift.

Its key advantage is clearly the cost. With an estimated annual spend of €22.37, it sits far below Ariel’s level. That makes it appealing for families who are constantly running the machine and looking for value for money.

If you wash a lot and rarely face extreme stains, Carrefour Expert is usually the cheaper route - while still delivering good cleaning performance.

Epsil Perfect Fraîcheur: strong when stains are pre-treated

In third place came Epsil Perfect Fraîcheur. It performed best when stains were briefly pre-treated before the wash. A small dab of detergent directly onto the mark, a short wait, then into the machine - under those conditions, Epsil cleaned very effectively.

With estimated yearly costs of €21.38, it offers an attractive balance between results and price. It also has a fresh fragrance that many users are likely to find pleasant. The trade-off is that you need to be willing to spend a minute or two pre-treating before washing.

Which detergent fits which everyday routine?

The results make one thing clear: there is no single perfect all-rounder for every situation. Choosing based on your own priorities is the sensible approach.

Priority	Recommended liquid laundry detergent	Notable point
Maximum stain removal, especially on whites	Ariel Original	Removes a very wide range of stains, bright whiteness, relatively expensive
Low costs when doing lots of washes	Carrefour Expert Optimal Clean	Good everyday performance, major price advantage
Pre-treatment is fine	Epsil Perfect Fraîcheur	Particularly effective after a brief direct application to the stain

If you regularly wash white shirts, bedding or tablecloths, Ariel can work well as a “special weapon” kept in the cupboard for the toughest loads. For standard everyday washing - T-shirts, jeans and sportswear - many people are better served by one of the cheaper contenders.

Chemicals in liquid detergents: what sensitive users should watch for

Another aspect highlighted in the test concerns ingredients. Many liquid formulas include preservatives such as isothiazolinones or phenoxyethanol. Both groups of substances are suspected of increasing the likelihood of allergies or skin irritation, especially for people with sensitive or already compromised skin.

If you’re prone to eczema, atopic dermatitis or contact allergies, it’s worth checking the label on the back of the bottle more carefully. In some cases, powders or detergent pods do better here because they can avoid certain preservatives.

Consumer specialists also point out that, on average, powder detergents often tackle stains a little more effectively than liquid detergents. Even so, many households still choose liquids for their convenience and ease of dosing - which is exactly why a comparison like this is so useful day to day.

Practical tips: how households can get more from their detergent

Whatever the brand, wash results depend heavily on how the detergent is used. A few straightforward habits can improve performance without using more product:

• Dose correctly: Too little detergent leaves stains behind; too much can leave residue and increases environmental impact. Always base dosing on local water hardness.
• Treat stains early: Rinse fresh tomato or red wine marks with cold water and don’t let them dry in.
• Pre-treat problem stains: Put a drop of liquid detergent directly onto grease, make-up or sauce marks and leave it briefly before washing.
• Choose the right temperature: Protein-based stains (e.g. blood) should be washed cold first, while grease lifts more easily at higher temperatures.
• Don’t overload the machine: If the drum is too full, water circulates less effectively and cleaning performance falls.

Why liquid detergents are so popular - and where they fall short

Liquid products score points for easy dosing, quick dissolving and often strong fragrances. They dissolve reliably at low temperatures and tend to leave less residue in the machine. Many users therefore see them as the more modern, convenient choice.

At the same time, tests repeatedly show that powders often have a slight edge on very stubborn stains, because certain bleaches and enzymes can be incorporated more effectively. Powders can also come out better on ingredients, particularly for anyone trying to avoid potential allergens.

A practical strategy is to keep both at home: a well-rated liquid detergent for everyday laundry and a strong powder specifically for white, heavily soiled loads. That makes it easier to adapt your routine without committing entirely to one format.

Understanding stain types: choosing more effectively

When you know how different stains behave, it becomes easier to pick the right detergent. Greasy sauces, make-up and oil, for instance, can be tackled well by enzyme-rich liquid detergents - especially if a little product is applied directly to the stain first. Pigment stains such as soil or ink respond better to bleaching agents, which are typically more prevalent in powders.

For households with children, keen gardeners or pet owners, it’s therefore worth paying attention to your most common “standard stains”. If most of your marks come from food in the kitchen, a high-performing liquid detergent such as Ariel - or one of the well-rated cheaper options - can take you a long way. Heavier outdoor grime or workshop dirt, by contrast, is more likely to call for a combination of pre-treatment and a specialist detergent.
