How to descale your Rocket Espresso machine (Appartamento, R58, Mozzafiato)

This guide covers descaling for Rocket Espresso machines — Appartamento, R58, R60V, R9, Mozzafiato, and the rest of the Italian E61 prosumer range. Rocket machines are heat-exchanger E61 machines with copper boilers and brass plumbing, which means they're durable but susceptible to scale damage if water management is neglected. The article explains why Rocket boilers should never see harsh chemistry — Cafetto descaler is the safe choice across all Rocket models, while aggressive industrial descalers can attack the copper. It walks through the descaling procedure with model-specific notes: when to draw descaler through both the steam and brew circuits, why the E61 group mushroom needs particular attention, and how to know when a Rocket has been neglected long enough to need a workshop intervention rather than a home clean. The article addresses the Rocket-specific maintenance questions Coffee Parts gets most often: how often, what about plumbed-in setups, can you descale through the rotary pump (yes, carefully), and what to do when the steam valve starts weeping after years of mineral exposure. Cross-sells include Cafetto descaler, E61 gaskets, mushroom kits, Coffee Parts silicone gaskets as the longevity upgrade over OEM rubber, and the BWT or Pentair water filter systems that prevent the problem recurring.
