Overview
Water carries minerals, and every time it heats, a little scale is left behind. It's invisible at first, but over time it slows your machine down, cools your brew and can shorten your machine's life. Descaling is the gentle reset that keeps everything flowing happily.
Simple to use. Urnex Liquid Dezcal is a ready-to-mix liquid for coffee makers, espresso machines and kettles. Urnex says one 33.6 oz bottle covers about 8 descaling cycles. Mix it with water as the label directs, run it through your machine's descale program (or brew cycle), then rinse with fresh water.
Check your manual first. Machines like the Bambino Plus and Moccamaster have their own descaling steps, and some makers recommend a specific product, so follow your manual. For coffee oils, use cleaning tablets instead; our cleaning and descaling guide explains the difference.
Soft-water bonus: filtered or softened water means less scale and better-tasting coffee, so you'll descale less often.
