Why choose it
The concentrate format behind Sanitify’s everyday probiotic spray — same formula, refillable, far cheaper per litre.
Clear routine. Lower chemical load. Built for repeat cleaning.
Works well with
One 500 ml bottle. Twenty bottles of living cleaner.
The probiotic universal cleaner you already know — now in a concentrated 500 ml bottle you dilute at home. One bottle of concentrate makes up to 20 bottles of ready-to-use spray, so you refill your own bottles again and again instead of buying single-use plastic, and give every room the same probiotic protection that keeps working for up to 72 hours after you wipe.
Why a concentrate
- Goes further, costs less per litre. One 500 ml bottle makes up to 20 bottles of ready-to-use cleaner — far cheaper per spray than buying bottles individually.
- Less plastic. Refill and reuse your existing spray bottles; one concentrate replaces a shelf of single-use cleaners.
- Keeps working. Beneficial probiotics settle into the surface and keep out-competing odour and grime for up to 72 hours.
- Gentle by design. Biodegradable, free from chlorine, phosphates and ammonia — safe to use around children and pets.
- Ready to go, free. A 500 ml spray bottle is included with every order, so you can dilute your first batch and start cleaning the moment it arrives.
How to use
- Add the recommended amount of concentrate to a clean spray bottle — as a guide, about 25 ml concentrate topped up to 500 ml with water, but always follow the exact ratio printed on your bottle.
- Top up with tap water and shake gently.
- Spray, wipe and walk away — the probiotics do the rest.
Where to use it
Kitchens, bathrooms, floors, worktops and everyday surfaces across homes, offices, hotels and food-prep areas. For a full breakdown by setting, see probiotic cleaning.
What one bottle actually costs you
25 € for the concentrate, up to 20 bottles of ready-to-use cleaner out of it — about 1.25 € per 500 ml bottle, against 5 € a bottle for our own pre-mixed spray. You're paying for the formula once instead of twenty times over in water and packaging.
Why probiotics outperform standard cleaners
Chemical disinfectants leave a bare surface — and a bare surface is an open invitation. Within hours, new bacteria and allergens settle back in. Diluted to the recommended ratio, this concentrate delivers the same living Bacillus cultures as our ready-to-use spray: they colonise the surface, consume the organic residue pathogens feed on, and keep out-competing them for up to 72 hours — long after a disinfectant's effect has worn off.
Which Sanitify cleaner do I need?
All four cover different jobs. Here's the honest comparison — including where each one falls short.
| Probiotic Concentrate 500 ml | Probiotic Spray 4×500 ml | Acidic Concentrate 500 ml | Acidic Spray 4×500 ml | |
|---|---|---|---|---|
| Best for | Everyday cleaning, if you'll reorder | Everyday cleaning, ready instantly | Occasional deep descaling, if you'll reorder | Mold, rust or limescale, ready instantly |
| What it does | Cleans + up to 72h probiotic protection | Strips mold, rust & limescale on contact | ||
| Before use | Dilute yourself — makes up to 20 bottles | Nothing — pre-mixed, spray straight away | Dilute yourself — makes multiple bottles | Nothing — pre-mixed, spray straight away |
| Price | 25 € (~1.25 €/bottle) | 20 € for 4 (5 €/bottle) | 29 € | 36 € for 4 (9 €/bottle) |
| Where it falls short | Needs a spray bottle and a minute of mixing before the first clean | Costs more per bottle over time | Won't stop mold or limescale coming back on its own — follow up with a probiotic clean | Costs more per bottle over time |
Not sure where to start? A single probiotic spray handles daily cleaning. Add the acidic cleaner only once you actually have mold, rust or limescale to strip — or get both in the Microbiome-Safe Cleaning Set.
