We offer Dezcal (Urnex Activated Descaler), a citric acid-based descaler that will remove mineral build up. This formula is nontoxic and biodegradable. Dezcal attacks lime scale and mineral deposits in places you cannot scrub with a brush: water lines, steamers and storage tanks in coffee brewers and espresso equipment.
This box contains 4 packets. Use one full packet to run through the coffee machine. That means a box should last you 2-4 months or longer depending on how mineral-rich your water is.
While the Urnex CleanCaf inhibits scale buildup and works as an effective cleaner, there are regions in the US where scale is a particular problem and you want a specific descaler. Lime scale and other hard water mineral buildup (including mineral calcium) can destroy equipment; it will build up on heat coils that have contact with water, in particular.
Your brewer or espresso machine will gradually fail to brew at the required 195-205°F brew temperature and coffee will taste dull and underextracted. Brewing coffee below the proper temperature will not make good coffee no matter what coffee you use!
