How to Use
Empty the water tank, pour in the full 100 mL bottle, and fill the tank with fresh water to the fill line, about 1 liter. Run your machine's descaling program, or brew the solution through in stages with pauses, until the tank is empty. Rinse the tank and run at least two tanks of clean water through before making coffee. Descale every 1 to 3 months depending on water hardness. Store closed, upright, at room temperature, out of reach of children.

Frequently Asked Questions
Which coffee machines is Acto Anti-Calc compatible with?
Acto Anti-Calc is a universal descaler for fully automatic and manual espresso machines, capsule and pod brewers, drip and filter coffee makers, and electric kettles. It works the same way as the manufacturer-branded descalers most machines specify. Always follow the descaling steps in your machine's manual, since some brands require a specific program or rinse count.
How do I use the 100 mL Acto Anti-Calc bottle?
Pour the whole 3.38 fl oz (100 mL) bottle into the empty water tank, top it up with fresh water to about 1 liter, and run the descaling program or brew the mixture through in stages. When the tank is empty, rinse it and flush the machine with at least two tanks of clean water before brewing coffee.
Is Acto Anti-Calc safe to use and store at home?
The lactic acid formula is biodegradable and designed to be safe for the seals, pipes, and heating elements of coffee machines, but it is still a cleaning product. Keep it out of reach of children, avoid contact with eyes and skin, rinse the machine thoroughly after use, and never drink the solution. Store the closed bottle upright at room temperature.
How often should I descale, and which pack should I choose?
Most machine makers recommend descaling every 2 to 3 months, or monthly in hard water areas, or whenever the descale indicator lights up. Since each 100 mL bottle is one cycle, a Pack of 3 covers a typical year with normal water and a Pack of 6 covers hard water or a busy household. Single bottles suit occasional use.
