Why switch
Simpler, cleaner, better value
No heavy bottle, no measuring cap, and a dose you match to how dirty your laundry is.
No heavy bottle or mess
Take a dry sheet from the pack: no lifting a heavy detergent bottle and no spilling liquid from a measuring cap.
Compact to store
The flat pack takes little cupboard space and is easy to keep by your washing machine.
Dose by soil level
Match the number of sheets to how dirty your laundry is. That way you do not automatically use more detergent than the dosing guide recommends.
Suitable for 20–90 °C
G6 is suitable for wash programmes from 20 up to and including 90 °C. Always choose a programme that suits your fabrics and care label.

Dosage guide
How to dose G5 and G6
Base the dose on the soil level. With G6 you can usually use half to one strip less than with G5.
Lightly soiled laundry
Normally soiled
Heavily soiled
Why G6 needs less: G6 contains 71% more active ingredients than G5 and has a thicker structure. This gives each sheet more cleaning power, so half to one strip less often provides comparable cleaning. Dose for cleaning power, not fragrance strength.
Up to 100 washes applies when using one strip per wash. If you use more strips, the pack provides fewer washes. Load size, water hardness and programme can affect the right dose.

Why Cosmeau
Improving until the difference is measurable
Not a one-off recipe, but six generations of learning from customer use, formulation and independent testing.

Improved over six generations
G1 → G6Each generation addressed a specific area: cleaning power, fragrance, colour care, stains or composition.

Independently tested
+32% / +24%G5: grass and mud / food stainsThe G5 results were measured by SGS in accordance with AISE protocols. Results vary by stain and situation.

More active ingredient, less PVA
+71% / −57%active ingredient / PVA per G6 sheet compared with G5A targeted formula comparison, not a claim that every wash performs 71% better.
A fair comparison: the percentages apply to the stated generation comparison. Fabric, stain, dosage and programme still affect the result.

Everything you want to know about laundry sheets
Clear answers about dosage for G5 and G6, scent, use, ingredients and what to expect.
How many sheets do I use per wash with G5 and G6?
Base the dose on how dirty the load is:
- Lightly soiled laundry: G5 1 sheet · G6 ½–1 sheet
- Normally soiled: G5 2–3 sheets · G6 1½–2½ sheets
- Heavily soiled: G5 3–4+ sheets · G6 2–3½+ sheets
With G6 you can usually use half to a whole sheet less. G6 contains 71% more active ingredients than G5 and is thicker, so each sheet holds more washing power. Load size, water hardness and programme can also make a difference.
Waarom heeft G6 minder strips nodig dan G5?
According to the formula comparison, G6 contains 71% more active ingredients than G5 and has a thicker build. This gives you more cleaning power per sheet, and you can often dose half to a whole sheet less. G6 also contains 57% less PVA than G5.
Krijg ik echt 100 wasbeurten uit één doos?
Up to 100 washes applies when you use 1 sheet per wash. For moderately or heavily soiled laundry you'll use several sheets, so you'll get fewer washes out of the pack.
Where do I put the laundry sheets?
Place your chosen number of sheets at the back of the empty drum, put your laundry on top and then start a suitable programme.
Op welke temperaturen kan ik G6 gebruiken?
G6 is suitable for wash programmes from 20 up to and including 90 °C. Always follow the care label on your clothes and your machine's instructions.
Why do I only smell the scent when I rub the laundry together?
Volatile fragrances mainly rely on a lot of chemicals. Our scent technology works through friction. Rub the laundry together and you'll notice a subtle scent. Higher temperatures or a tumble dryer have a negative effect on the scent. For the best scent experience, wash at 30–40 °C and let your laundry air-dry.
Why can't I smell anything straight after washing?
Straight after washing you often won't smell anything yet. Wash at 30–40 °C and hang your laundry to air-dry. At high temperatures or in the tumble dryer, some of the scent is lost. Once the laundry is dry, rub the fabric together for a subtle scent. You can use 1 or 2 extra sheets to see whether that's the cause. The dosage is based on cleaning power, so for more scent you can dose a little extra or add scent beads or laundry perfume.
Why is the scent milder than with pods?
Straight after washing you often won't smell anything yet. Wash at 30–40 °C and hang your laundry to air-dry. At high temperatures or in the tumble dryer, some of the scent is lost. Once the laundry is dry, rub the fabric together for a subtle scent. If you like stronger scents, combine with scent beads or laundry perfume. A sheet weighs only about 4 grams, so it holds less fragrance than a pod of around 20 grams.
Why does G5 smell different out of the box?
The newer generation can smell different because of a different mix of ingredients. For example, enzymes have been added for extra cleaning power, but they smell less "nice". You won't notice it after washing, but you will in the box. We keep working on this, but with G5 we chose cleaning power.
Why does my laundry smell musty after using laundry sheets?
That doesn't mean the laundry sheets aren't working. Other detergents often mask odours with strong perfume, while laundry sheets have a milder scent. Because of its low weight, a sheet is less able to mask odours already present in the washing machine or clothes. Use our deep-cleaning tablets for the washing machine to check whether the machine itself is passing on odours.
Bevatten G6 Wasstrips PVA?
Yes. G6 contains PVA, but according to the formula comparison 57% less than G5. That's why we call the cardboard product packaging plastic-free, not the entire product.
What do the five enzymes do?
During the wash, the five enzymes help loosen different types of dirt, including protein, grease, starch, thickened food and fluffy textile fibres.
Can I use G6 for all colours and fabrics?
Choose the variant that suits your laundry and always follow the care label. For delicate materials, only use a variant and programme that are suitable for them.
Is G6 suitable for sensitive skin or baby laundry?
We don't make a general hypoallergenic promise here. Check the current ingredient and allergen information, and stop using the product if you have an unwanted reaction.
Lost G6 ook op bij 20 °C?
G6 is suitable for programmes from 20 °C. Place the sheets as instructed, don't overload the drum and choose a suitable programme.
How do I store the sheets?
Keep the box tightly closed in a cool, dry place. Always keep detergent out of reach of children and pets.
