Washing Machine Cleaner Tablets — Hard Water Formula
An enzyme descaler that clears limescale from the drum, element and pipes — and stops it resettling.
- Citric-acid descaler dissolves limescale on the element, drum and pipes
- Protects the washing machine and stops loosened scale resettling
- Fragrance-free · septic-safe · works in every washing machine
- 24 tablets · a full 12-month supply
What’s in the Formula
Citric acid — the descaler, at 10–30%. Dissolves limescale on the heating element, drum and internal pipes.
Sodium percarbonate (oxygen bleach) lifts the detergent residue and grime trapped under the scale, and brightens — no chlorine. Sodium carbonate softens the wash water.
Sodium silicate protects the washing machine’s metal parts from corrosion. Sodium polyacrylate keeps dissolved minerals suspended so they flush out instead of resettling. A fatty-alcohol cleaning agent cuts through the mineral film. Four enzymes (protease, lipase, alpha-amylase) clear organic grime, and tea polyphenols keep it fresh, fragrance-free.
Full ingredients (from the SDS): Citric acid 10–30% · Sodium percarbonate 10–30% · Sodium carbonate 10–30% · Sodium silicate 1–5% · Sodium polyacrylate 1–5% · Fatty alcohol polyoxyethylene 1–5% · Alkali protease, protease, lipase, alpha-amylase 0.1–1% each · Tea polyphenols 0.1–0.5%. No chlorine bleach. Septic-safe.
How to Use
Run one tablet on an empty 60–90°C cycle (or your washing machine’s drum-clean setting), twice a month. Place it straight in the empty drum — not the detergent drawer. It clears the heating element, restores efficiency and extends the life of the washing machine.
How is it different from Calgon?
It’s used differently. viblii does contain water softeners — washing soda and citric acid — but it’s run on an empty cycle to remove the scale that’s already built up and clean the washing machine, rather than being dosed into every wash the way Calgon is to limit new scale during a load. Many hard-water households use both.

Heats faster. Washes cleaner. Lasts longer.
- Restored efficiency. A scaled-up element heats slowly and wastes energy — clearing it brings the washing machine back.
- A washing machine that lasts. Descaling the drum, element and pipes prevents the damage hard water does over time.
- Fresher laundry. Scale traps detergent residue and odour; clear it and washes come out cleaner.
- Pennies per clean. Around £0.58 a wash — a full year of descaling in one box.
The scale you can’t see
In hard water areas — 200+ ppm: London, the South East, East Anglia and the Midlands — limescale builds on the heating element, drum and pipes with every wash. You can’t see it, but it makes the washing machine work harder, heat slower and wear out sooner. Ordinary cleaners don’t shift it.
Built to clear scale — and what’s under it
A genuine descaler, oxygen bleach, three enzymes and a natural deodoriser — each with a job to do.
Citric aciddissolves limescale
The descaler, at 10–30% of the formula. It dissolves the limescale coating the heating element, drum and pipes in the same hot cycle.
Oxygen bleachlifts trapped residue
Sodium percarbonate releases active oxygen to lift the detergent residue and grime trapped under the scale, and to brighten — without chlorine.
Proteaseprotein & organic grime
Breaks down the protein-based grime and organic residue that collects in the drum and seal beneath the scale layer.
Lipaseoils & grease
Dissolves the oils and grease that coat internal surfaces and hold other residue in place against them.
Amylasedetergent & starch film
Clears the starch-based detergent and softener film that lines the drum and pipes and traps odour.
Tea polyphenolsfragrance-free freshness
A plant deodoriser that clears the musty smell of build-up at the source — no synthetic perfume covering it up.
It removes scale — and stops it coming back
Dissolving limescale is only half the job. This formula also protects the washing machine and stops the scale it loosens from settling straight back down.
- Sodium silicate — shields the metal parts from corrosion
- Sodium polyacrylate — keeps dissolved scale suspended so it flushes out, not resettles
- Fatty-alcohol cleaning agent — cuts the mineral film so the descaler reaches the surface
Three Steps. Twelve Months.
Drop
Place one tablet directly in the empty drum — not the detergent drawer. No prep, no measuring.
Hot cycle
Run an empty 60–90°C cycle, or your washing machine’s drum-clean setting. The tablet dissolves completely.
Sorted
Repeat twice a month. 24 tablets in the box — a full year of descaling handled in one purchase.
viblii vs a water softener (Calgon)
Different routines, not rivals. Both soften hard water — but viblii also clears the scale that’s already built up and cleans the washing machine on an empty cycle, while Calgon tops up softening in every wash. Many hard-water homes use both.
Reviews
Questions.
Is this the same as Calgon?
They’re used differently. viblii does contain water softeners — washing soda and citric acid — but it’s run on an empty cycle to remove the limescale already built up on the element, drum and pipes and to clean the washing machine, rather than being dosed into every wash the way Calgon is to limit new scale during a load. Many hard-water households use both.
Which water areas is it for?
It’s built for hard and very hard water — roughly 200+ ppm — which covers London, the South East, East Anglia and much of the Midlands. It works anywhere, but it earns its place fastest where scale builds quickly (a kettle that furs up in weeks is the tell).
Does it really descale the heating element?
Yes. Citric acid makes up 10–30% of the formula — a genuine descaler. On a hot cycle it dissolves the limescale on the element, drum and pipes, which restores heating efficiency and helps the washing machine last longer.
Will it work with my washing machine?
Yes — front-load, top-load and HE machines from every major UK brand: Samsung, Bosch, LG, Hotpoint, Beko, AEG, Miele and more. Septic-safe, no chlorine bleach.
How often should I use it?
Twice a month — one tablet in the empty drum on a hot cycle (60–90°C) or your washing machine’s drum-clean setting.
Is it scented? What’s in the box?
Fragrance-free — tea polyphenols neutralise odour rather than masking it. Each box has 24 individually-wrapped tablets, a full 12-month supply.
