Trusted industry standard

Widely used by service technicians and cafés to restore flow, temperature stability and cup consistency after scale build-up

Mineral scale (limescale) reduces heat transfer, raises energy use and eventually causes inconsistent brewing or machine failure. Urnex Dezcal is an activated descaling powder designed to break down those mineral deposits quickly and safely so machines perform like new again. The formula is odour-free, rinses away thoroughly and is formulated to be biodegradable — a practical alternative to household vinegar that won’t leave behind off-odours or tasting notes.

Dezcal works across a wide range of water-handling components: boilers, hot water tanks, steam wands, spray heads, kettles and internal plumbing where scale collects and is hard to reach. For the 900 g jar Urnex provides clear bulk mixing guidance (see specs), and the powder dissolves in warm water to produce a descaling solution that can be circulated through the machine or used to soak removable parts. Because Dezcal attacks scale chemically it reaches places that brushing can’t, preserving components and restoring consistent water flow and temperature stability.

The 900 g format is aimed at cafés, service technicians and serious home users who prefer a single bulk supply for scheduled maintenance. It reduces packaging waste versus many single-use packets and gives you flexibility on concentration and contact time depending on how heavy the scale is and the make/model of equipment.

Safety and correct rinsing are essential. Always follow machine manufacturer descaling instructions in addition to product directions: circulate the solution as directed, allow recommended soak times, then flush multiple full tanks of clean water until no residue remains. Consult the product SDS for handling, PPE and environmental guidance — Dezcal’s SDS details containment, first-aid and disposal measures for safe use. Regular descaling (intervals depend on water hardness and throughput) prevents taste issues, maintains efficiency and extends component life.
