Laundry Detergent Sheets FAQ: use, dosage, scent and stains

Laundry detergent sheets are thin, dissolvable sheets of concentrated detergent. You use them as an alternative to liquid detergent, powder, or pods, without bulky plastic bottles or heavy boxes.

Choose the version that matches your laundry

If you mainly want more scent in your laundry, you can always combine your detergent sheets with scent beads or laundry perfume.

Place the detergent sheet at the bottom of the drum or in the detergent drawer, then put your laundry on top. Leave about a fist-width of space between the laundry and the top of the drum so water can circulate properly.

Use 1 sheet for about 5 kilos of lightly to normally soiled laundry. Use 2 sheets for a bigger load, dirtier laundry, hard water, or if you want extra scent. For very dirty laundry, you can use 3 sheets.

For a large 8 or 9 kg drum, many people use 2 sheets. If the laundry is genuinely dirty, you have hard water, or you want extra scent, you can increase that to 3 sheets.

Yes, good laundry detergent sheets work very well for normally soiled laundry. For clothes, towels, and bedding, they are a practical and clean solution for everyday use.

Yes, but it depends on the formula. The current Cosmeau G5 formula was specifically developed for common stains such as grass, mud, and food stains, based on independent SGS testing.

If stain removal matters most to you, choose a formula with multiple enzymes. Cosmeau uses 5 enzymes that target common stains such as grass, mud, food, grease, and protein stains.

Wet a small piece of the sheet and rub it directly onto the stain for extra pre-treatment. Then wash the garment as you normally would.

Yes, Cosmeau detergent sheets dissolve from 15 degrees and are especially practical for lower temperatures such as 30 or 40 degrees. That works well for everyday laundry and also helps save energy.

Yes, the sheets are suitable for all temperatures from 15 to 90 degrees. Just keep in mind that scent is often preserved better at lower temperatures.

Yes, as long as the sheet gets enough water to dissolve properly. On quick cycles it helps not to overload the drum, or to place the sheet in the detergent drawer.

Yes, you can. Dissolve an appropriate amount of the sheet in water and use less product than you would for a full machine wash, so your fabrics get clean without overdosing.

Place the sheet in the detergent drawer or make sure the drum is less full. Incomplete dissolving usually happens because there is not enough water flow or because the sheet gets trapped awkwardly between the laundry.

Yes, laundry detergent sheets are suitable for whites. If you want extra focus on keeping whites bright, a dedicated formula for white laundry is often the best choice.

Yes, detergent sheets can work very well for dark laundry. If colour care matters more to you, you can choose a special version for black or dark fabrics.

Yes, especially at 30 or 40 degrees, detergent sheets are handy for sportswear. For sweat odours or stubborn dirt, a slightly higher dose or pre-treating the stain can help.

Yes, as long as you choose a mild formula. For sensitive skin, irritation, or eczema, a fragrance-free and dermatologically tested version is usually the safest option.

For sensitive skin, a fragrance-free and dermatologically tested version is usually the best choice. That keeps the formula as mild as possible and avoids unnecessarily strong fragrance ingredients.

Not by default. For wool, silk, and other delicate fabrics, it is better to use a dedicated wool and silk version, because regular all-purpose detergent sheets are not the best choice for them.

Usually not. Cosmeau positions these sheets as a 5-in-1 solution for colours, whites, darks, softness, and scent, so many people no longer use a separate fabric softener.

Detergent sheets usually give a subtler scent than heavily fragranced liquid detergent. If you want more scent, choose a stronger fragrance variant or combine them with scent beads.

With detergent sheets, the scent often releases more subtly during the wash. Once the fabric is dry and rubs against itself, you often notice the scent much more clearly.

Wash slightly smaller loads, consider using 2 sheets instead of 1, dry the laundry quickly, and check whether the washing machine itself is clean. A dirty machine is a common cause of musty-smelling laundry.

Detergent sheets are lighter, more compact, and easier to dose and store. You do not need heavy bottles and you use less packaging volume than with traditional liquid detergent.

That depends on what matters most to you. If you want convenience, compact storage, less lifting, and plastic-free packaging, detergent sheets are often more practical. If you mainly want the familiar format of liquid detergent, some people still prefer that.

Pods are pre-dosed and less flexible, while detergent sheets are easier to adjust in quantity. Detergent sheets also take up very little space and are handy for small homes, travel, or camper vans.

They certainly can be. According to the product page, Cosmeau detergent sheets start at around 14 cents per wash, compared with about 28 cents for liquid detergent and 40 cents for pods.

Cosmeau detergent sheets are consistently one of the most affordable options on the market and, with the right offers, often by far the cheapest, especially if you subscribe to the newsletter. The value for money is even stronger because we are the only detergent sheet brand on the market using 5 enzymes against the most common stains.

Cosmeau detergent sheets are made from a combination of cleaning agents, binders, water softeners, fragrance ingredients, and enzymes. Think of ingredients such as PVA, sodium dodecyl sulphate, sodium olefin sulfonate, glycerine, trisodium citrate, and various enzymes.

Enzymes are active ingredients that break down specific types of dirt. That allows detergent sheets to work better at lower temperatures on grease, starch, protein stains, and dull buildup.

In the product information, Cosmeau mentions mannanase, amylase, protease, lipase, and cellulase. Each enzyme helps with a different type of dirt or helps keep fabrics looking better.

Protease helps break down protein stains such as blood, dairy, and egg. That can noticeably improve cleaning performance on this type of dirt.

Amylase breaks down starch from stains such as pasta, rice, or sauce. It is especially helpful for food residues that are otherwise harder to wash out of fabrics.

Lipase targets fats and oily stains. This enzyme also works well at lower wash temperatures, which is useful for everyday laundry.

Mannanase helps break down plant-based dirt such as grass, mud, and some vegetable stains. That is exactly why this enzyme works well for family laundry and outdoor clothing.

Cellulase helps remove tiny fibre residues from cotton-like fabrics. That can help colours stay fresher for longer and make laundry look dull less quickly.

According to the product page, the sheets are free from harsh substances such as parabens, phosphates, and chlorine bleach. Colourants and other aggressive chemicals are also explicitly avoided.

For many households, yes, mainly because of the lower packaging volume, light weight, and the fact that you do not need large plastic bottles. That makes them more practical for transport and storage.

The packaging is plastic-free and FSC-certified. Cosmeau is more nuanced about the sheets themselves: they contain PVA as a dissolvable carrier, which is why the newest packaging specifically refers to plastic-free packaging rather than a fully plastic-free product.

That is a topic many people search for. Cosmeau explains that some parties do not consider PVA a microplastic, while others still question it. That is why Cosmeau communicates about this carefully and is also working on alternative carriers.

According to the product information, the sheets are largely biodegradable. Cosmeau also refers to certified biodegradability of the PVA used, based on OECD-B301.

PVA is a water-soluble polymer that helps give the sheet its solid shape and dissolves during the wash. Cosmeau describes this as a grey area in the market and is therefore also researching cellulose-based alternatives.

According to the product page, the detergent sheets are dermatologically tested and are also recommended by skin therapist SPROET. For very sensitive skin, fragrance-free is still usually the most sensible choice.

G5 stands for the fifth generation of the Cosmeau detergent sheet formula. This version was further developed based on customer feedback and test results, with extra focus on common stains such as grass, mud, and food.

That is because the formula has been adjusted. Cosmeau indicates that the scent of G5 can differ slightly from G4, partly because it was brought closer to the Spring Fresh scent beads.

Yes, but with hard water you often need a little more product. That is why Cosmeau usually recommends 2 sheets instead of 1 in hard water, depending on the load and the level of dirt.

At the moment, our detergent sheets are produced in China because they are currently the only ones with the technology to work with solid enzymes without compromising performance. In 2026, we will move production to our own factory in Velsen-Noord.

Store detergent sheets in a dry place and out of direct sunlight. Well-sealed packaging or a storage box helps keep the sheets neat, usable, and pleasantly scented.

If you store them dry and properly sealed, detergent sheets stay usable for a long time. Above all, avoid moisture and direct sunlight, because they can affect the structure and scent.
