De'Longhi MultiClean

MultiClean is De'Longhi's liquid cleaner for the milk circuit of coffee makers, sold in a 250 ml bottle under code DLSC550. The manufacturer describes it as a deep-cleaning solution for the milk circuit, including the carafe and steam wand, aimed at removing milk proteins and fats left behind by frothing. The page states it is suitable for all coffee makers in general, not only De'Longhi models.

The intended use is twofold: the liquid can be poured directly into the milk jug and circulated by pressing the machine's milk delivery button, or applied to a cloth to wipe down external surfaces and removable parts. De'Longhi states the formulation is made from more than 99% readily biodegradable ingredients and describes it as gentle on hands, though the page does not list an ingredient breakdown or an explicit food-contact safety statement.

It is a targeted maintenance product: it works on the milk circuit and external parts, not on the brew group or water circuit, so it does not replace a descaler or a dedicated boiler cleaner. It sits within De'Longhi's own-brand care accessory line, covered by the manufacturer's warranty like other genuine parts.
