Pulycaff — Nettoyant pour machine espresso

Pulycaff remains the cleaner most Roman cafés reach for — not because of marketing, but because baristi who run twenty kilos daily know what preserves a group head. This alkaline powder, formulated in Italy and packaged in the 900-gram format that covers roughly six months of weekly backflushes, removes coffee oils without scoring chrome or degrading seals. The chemistry is straightforward: sodium metasilicate lifts polymerized triglycerides, sodium carbonate buffers pH, and the surfactant system rinses clean in three cycles, leaving no residue that might taint tomorrow's espresso.

Most home machines tolerate monthly backflushing; commercial groups demand weekly attention. Pulycaff's dosing is forgiving — one level scoop (roughly 4 grams) inserted into a blind basket, then five ten-second pulses with thirty-second rests between. The powder foams brown, then beige, then white as oils emulsify and flush through the three-way valve. After the fifth cycle, remove the basket, run two blank flushes, wipe the dispersion screen with a nylon brush, and reassemble. Total time: four minutes. The alternative is extraction that slows by fifteen percent over three months as rancid oils coat the shower screen, or worse, a 1,200-euro valve replacement when residue hardens into varnish.

The 900-gram canister uses a wide-mouth design and includes a measuring scoop clipped inside the lid — details that matter at six in the morning. The powder itself is white, odorless, and hygroscopic, so keep the lid sealed between uses. Unlike enzymatic cleaners that require overnight soaking, Pulycaff works in seconds because it's designed for the tempo of café service, not the luxury of downtime. Some roasters rebrand this same formulation at triple the price; we simply stock the original.

This is for anyone who considers a three-thousand-euro espresso machine an instrument rather than an appliance. If you backflush with water alone, you're removing crema but leaving behind the oil film that turns every shot slightly bitter after two weeks. If you've never backflushed at all, you're gambling that the group head will forgive neglect — it won't. Pulycaff is the cost of a single bag of coffee and extends machine life by a decade. The mathematics are unambiguous.
