Best coffee machine descalers compared in 2026

Coffee machine descalers come in different formats, so it helps to pick one that suits your machine. This roundup compares five options: two liquids, De'Longhi EcoDecalk and EQM ECO-212, which are general-purpose rather than machine-specific; two machine-specific products, the Nespresso pouches and the Bosch Tassimo tablets; and ACTIVE, a 24-tablet pack listing many named brands. Formats include 500ml bottles, two 100ml pouches and tablet packs, and the instructions differ between them, so these products are not interchangeable. Always check your machine's manual and the product's compatibility information before buying.

De'Longhi Decalk - Coffee Machine Descaler 5 Decalcification Doses

Our Top Pick

De'Longhi EcoDecalk

It is a plant-based lactic acid liquid described as universal, though its instructions reference De'Longhi machines.
