Foam Explosion

Sprinkle 2 heaped spoons (±100g) into the toilet bowl. For the best foam effect, add a splash of warm water first – it makes the foam rise faster and higher. Leave it to fizz for at least 3 minutes. Once the foam has settled, you can give a quick brush or let it sit longer for a deeper clean. Flush when you’re happy. For stubborn stains, leave it overnight. Use 1–2 times per week for best results.

Tip: In soft or low-mineral water, the foam may be less dramatic. Use warm water or a slightly bigger dose to boost the effect.

Yes – and that’s what makes it different. Unlike classic cleaners that simply mask smells with perfume, YOKUU tackles the source. Our 1 billion probiotics break down the residues that cause odours – even under the rim or deep in the pipes where brushes can’t reach. They keep working after you flush, so smells and hidden grime don’t come back as quickly.

Yes. The formula actively supports a healthy microbiome in your septic tank – completely safe.

Because there’s no bleach, no harsh acids, and no microplastics. Instead, Foam Explosion uses biodegradable ingredients and probiotics that continue breaking down dirt and smells even after flushing. The powder is light, compact, and plastic-free, so we’re not shipping heavy bottles of water around – that cuts CO₂ emissions by up to 90% per pallet. The packaging is compostable, and you use only what you need – no waste. Plus, it doesn’t harm water systems, unlike traditional cleaners with EDTA or synthetic perfumes. Cleaner toilet, lighter footprint.

Yes – once you’ve flushed. During use, keep the powder out of reach of children and avoid eye contact or inhaling the powder.

Foam Explosion contains small traces of fragrance allergens (like linalool from lavender), which could trigger a reaction in very sensitive people. The amount is tiny, and since the product is used in the toilet (not on skin), exposure is minimal. Risk is very low. If you’re unsure, try it in a well-ventilated space first or ask us for the ingredient list – we’re happy to help.

We don’t recommend mixing it with classic bleach- or acid-based cleaners, as they can interfere with the probiotics. You can alternate with YOKUU’s Toilet Bombs: use Foam Explosion once a week for deep cleaning, and Toilet Bombs in between for a quick refresh. Using both at the same time isn’t necessary – save the foam party 😉.
