About Acto
Acto is a European household and appliance care brand specializing in descaling and cleaning solutions for espresso machines and other household appliances. The Anti-Calc Descaler uses a lactic acid formula — effective against limescale while being safe for use in all types of machines.
Frequently Asked Questions
- What is lactic acid and why is it used in descalers?
- Lactic acid is a natural organic acid produced by fermentation. It is highly effective at dissolving calcium carbonate (limescale) deposits while being gentler on machine components than stronger mineral acids like citric acid or sulfamic acid. It leaves no toxic residues after rinsing, making it a safe and effective choice for descaling espresso and coffee machines.
- How often should I descale my machine?
- Acto recommends descaling every 3 months, or more frequently in hard water areas. Signs your machine needs descaling include slower brewing, reduced steam pressure, unusual noises, or coffee that tastes flat or bitter.
- Is Acto Anti-Calc compatible with my machine?
- Yes. Acto Anti-Calc is designed for universal compatibility with all brands and types of espresso machines, pod/capsule machines (Nespresso, Keurig, Dolce Gusto, etc.), and drip coffee makers. Always follow your machine manufacturer's descaling instructions.
