Urnex Dezcal™ Activated Descaler Powder – 4 Single-Use 1 oz Packs
Fast, Effective Descaling for Espresso Machines, Home Brewers, Kettles & Pod Machines
Mineral scale is one of the most common and most overlooked threats to coffee equipment performance. As hard water passes through boilers and heating elements, it leaves behind limescale deposits that restrict water flow, lower brew temperatures, and gradually degrade the taste of your coffee. Urnex Dezcal Activated Descaler Powder dissolves those deposits fast, restoring your machine to peak performance with a non-toxic, biodegradable, odorless, and phosphate-free formula. Each box contains 4 single-use 1 oz packets perfectly portioned for hassle-free descaling at home or in low-volume café settings.
Features:
- Activated Descaling Formula — Specifically formulated to break down and remove limescale and mineral deposits from boilers, heating elements, hot water tanks, faucets, and spray heads
- Compatible with a Wide Range of Equipment — Safe for use on home brewers, traditional and automatic espresso machines, kettles, pod machines, and capsule machines
- Non-Toxic, Biodegradable & Phosphate-Free — A safer, more environmentally responsible alternative to vinegar and harsh chemical descalers
- Odorless Formula — Unlike vinegar, Dezcal is completely odorless and rinses away cleanly without leaving an aftertaste that can affect your coffee's flavor
- NSF Certified for Metal Compatibility — Tested and certified safe for use with metal machine components including boilers and heating elements
- Single-Use Packets for Easy Dosing — Each of the 4 packets contains exactly 1 oz (28g) — the precise amount needed for one full descaling cycle — no measuring required
- Restores Machine Performance — Regular descaling with Dezcal helps maintain consistent brew temperature, water flow, and extraction quality
