Let customers speak for us
from 1259 reviewsThis spray really takes care of all the smells there can be in a household with 2 boys 😉.

I was finding that some of my washing (gym kit in particular) was coming out of the machine smelling 'cheesy.' I tried a variety of methods to eradicate this problem using all natural detergents as this is my preferred option. I deep cleaned the machine but was still getting the odour. I then saw an ad for Yokuu and it suggested that there was a build up of bacteria in the machine and that washing at lower temperatures was partly to blame. I felt I had nothing to lose, so purchased the sample pack. I am pleased to say that it has done the job and my gym kit smells lovely now!
I can also say that the toilet bomb works at treat too. Happy days!

I have had a dark spot in my toilet for ages. Tried a lot of other cleaning products but they never worked. It took only 2 toilet bombs to completely remove it.

The strips do what they’re suppose to do: wash and clean your laundry! Really good results and while using them, you’re also diminishing your ecological impact.

We like the subtle sent and they feel on our skin. And it's economical in use!

I love love love everything so far. Used the toilet bombs, they’ve helped with an old toilet I had already tried everything on. The surface cleaner works really on ALL surfaces, the glass cleaner is super and effortless, I love the hand and body wash. I didn’t yet use the floor cleaner, dishwasher tabs and washing machine sheets as I still had some old products to finish but I can’t wait to give them a go

Cleans well and does not leave residue on the dishes. Tried with dried tomato sauce left on a pan and was satisfied with result. Would recommend.

does the job really well, and lovely smell (not strong but fresh)

I was one of the people dragging home 2,5 l plastic jars from the eco-store..and now I only need a strip or two, weighs next to nothing and is delivered to my home. Me and the environment are totally pleased. Add to this that they wash cleaner than the normal stuff + also works for silk, linen and wool = I no longer need to have three different washing powders in my tiny cupboards. All in all -this makes me happy)

I am in love with your products ! And just found THE perfect loundry sheets, thank you!

We were already sold on the cleaning products and were eager to try the hand and body soap. Very pleased with the products! The hand soap smells very good and the foam-pump does a great job. Our skin is very sensitive and does not react to the products, so it's a win!

OMG I have been using for a few weeks now and everything has that 'new' look. Cleaning is much easier, dirt isn't as stubborn, no scrubbing with the mop just 'Wipe n go'' Also I have noticed that my mop head remains clean, its like the microbes are munching all the dirt. Go Yokuu, go!

When I bought my house, I seriously thought I'd have to buy a new toilet. I had no hopes of ever getting it clean. Okay, it took 3 bombs, but it is now SPOTLESS and I'm speechless. I wish I had taken a "before" picture, because it's actually hard to believe. The other toilet, which was also pretty crusty, took only one bomb. I love it! And all that without any nasty smells. You don't even want to know what all that other stuff we tried smelled like. And that didn't even do anything.
So in conclusion: This stuff is pricey, but so worth it!

Tous les produits sont super faciles d’utilisation et très efficaces. J’ai essayé pas mal de marques de produits ménagers avec un système de recharge et d’abonnement mais celle-ci est ma préférée 🤩
Heel tevreden met mijn aankoop 😊. Niet alleen een top product maar het ruikt ook super lekker. Ik hou er van dat dit product tot in de puntjes 'groen' is, tot de verpakking toe.
Ik werk in een tweedekans kleding winkel waar veel inbreng van kleding is waar onbestemde vlekken in zitten die er ogenschijnlijk niet meer uit gaan, ook niet met de chemische vlekkenverwijderaars. Maar als ik die kleding een dagje meeneem en blootstel aan de vlekkenfluisteraar … dan gebeuren er wonderen. Als de vlek ook maar enigszins van biologische oorsprong is, dan lusten de microben daar wel pap van en is de vlek zomaar ineens verdwenen.
Moet je wel even een schepje oplossen in warm water, even wachten, dan op de vlek scheppen en laat maar even rusten, een nachtje doe ik meestal. Kom je terug en is de vlek nog lichtelijk aanwezig? Gewoon even met warm water spoelen en voila. Het kledingstuk hoeft niet in zijn geheel gewassen te worden als het al schoon was (behalve de vlek).
Ik ben inmiddels bekend als vlekkentovenaar, maar ik heb dan ook de beste assistent: de YOKUU vlekkenfluisteraar!!

Pssst... Here's the answers you're looking for

Hey, I'm Joris - the founder of YOKUU!
Whilst writing my bio-engineer thesis, I discovered that 99% of bacteria are healthy... So why are we so obsessed with killing them?
Here's a couple of our most frequently asked questions:
Collapsible content
+ What kinds of stains does it work on?
The Stain Whisperer loves anything alive - or once alive. Think wine, fat, blood, coffee, grass, sauce, baby’s first carrot puree... If it comes from nature, it’s fair game. For inorganic stuff like ink or paint, it’ll try, but those aren’t its favourite conversation partners. Luckily, 98% of stains are organic - and this whisperer’s an expert at those.
To avoid unexpected stains or fabric damage, we recommend not using the stain remover in the following situations:
- ❌ On sunscreen stains (especially mineral sunscreens with zinc or titanium dioxide) - these can react with the active oxygen and cause orange stains.
- ❌ On delicate fabrics like wool, silk, or leather - the high pH and bleaching agents may damage the fibres.
- ❌ On metal parts of clothing (buttons, zippers) - avoid direct contact, as oxidation may occur.
- ❌ For soaking longer than 1 hour - this increases the chance of discolouration, especially on white fabrics.
- ❌ With hot water - lukewarm water works best. Hot water can speed up unwanted reactions.
+ Is it suitable for both white and coloured laundry?
The Stain Whisperer comes in two versions: one for whites and one for colours. The white version includes a natural bleaching boost (soda + oxygen) to brighten and keep whites white. The coloured version is a little gentler, without bleach - so your colours stay vivid. White gets bright, colour stays colour. Now that’s whisper-work.
+ How do I use it?
The Stain Whisperer adapts to your cleaning mood.
Use A – for the lazy cleaners: Add one tablespoon (30g) to the detergent drawer, with your usual detergent. Use two for heavy stains.
Use B – for the semi-motivated: Dissolve 1 tablespoon in 2L of warm water and soak for up to an hour.
Use C – for the precise ones: Mix ½ tbsp with water, apply to the stain, let sit for 5 mins, then wash as normal. Check the pack for more.
+ How long should it soak in?
Depends on the method. For direct treatment (C), let it sit for at least 5 minutes—longer for tough stains. For soaking (B), up to 1 hour. In the machine (A), it does the work while you relax.
+ Does it work at low temperatures?
Yes, even at 30°C or colder. Enzymes break down stains at low temps, while the bacteria keep cleaning, removing odours and improving hygiene in your drum and on fabrics. It’s a deep clean on eco mode.
+ Is it safe for delicate fabrics like wool or silk?
The Stain Whisperer is gentle on most fabrics, but you should be cautious with silk, wool, cashmere, suede or leather. These don’t play well with enzymes and moisture. If in doubt, test a small area first.
+ Can I use it with other laundry products?
Yes, especially with YOKUU’s laundry sheets. They’re made to work together. Both contain probiotics that boost each other’s effects. You can still use it with classic detergents, but you’ll miss out on the full YOKUU experience.
