Why choose it
The acidic half of the two-step system behind the Microbiome-Safe Cleaning Set — deep-clean first, probiotic shield second.
Clear routine. Lower chemical load. Built for repeat cleaning.
Works well with
The heavy-duty concentrate for mold, rust and limescale.
Some jobs need more than probiotics alone — mold that's already taken hold, rust stains on fittings, limescale built up in sinks and around taps. Sanitify's acidic cleaner concentrate is a salt-based, biodegradable descaler that strips all three at the source. Dilute it at home to make bottle after bottle of ready-to-use cleaner, instead of buying single-use sprays one at a time.
Why a concentrate
- Heavy-duty where it counts. Strips mold, rust and limescale from sinks, tiles, taps and equipment — the jobs a gentle probiotic spray isn't built for.
- Goes further per bottle. One 500 ml concentrate dilutes into multiple bottles of ready-to-use descaler.
- Still biodegradable. Salt-based acidic formula — no bleach, no phosphates.
- Works with the probiotic system. Use it first to strip mold and residue, then follow with a Sanitify probiotic spray to keep the surface protected for up to 72 hours afterwards — the same two-step logic behind the Microbiome-Safe Cleaning Set.
How to use
- Add the recommended amount of concentrate to a clean spray bottle and top up with water.
- Apply to the mold, rust or limescale and let it sit briefly before wiping or rinsing.
- For lasting protection, follow up with a Sanitify probiotic cleaner once the surface is dry.
Where to use it
Bathroom tiles and grout, sinks, taps, shower doors, and other hard surfaces where mold, rust or limescale have built up. For everyday surface cleaning between deep cleans, see probiotic cleaning, or read about the full 2-step approach on our mold removal page.
