Quick question: when did you last clean your coffee machine's brew chamber?
Not descale it. Clean it.
Most of us are pretty good about descaling these days. Machine manufacturers have done a solid job getting that message out. But cleaning tends to get skipped, or people assume a rinse (or a splash of vinegar) is doing the job.
It isn't.
Here's what's actually happening inside your bean to cup machine:
☕ Every shot leaves coffee oils and grounds behind in the brew chamber
💧 Every drop of water leaves mineral deposits behind in your water circuit
These are two completely different problems, in two different parts of the machine, and they need two different solutions.
A rinse moves loose grounds out of the way, but it doesn't touch the oily residue building up shot after shot. Left long enough, that residue can turn rancid, and a warm, damp brew chamber is exactly the kind of place mould can take hold if it isn't properly cleaned.
Vinegar isn't the answer either. It's not formulated to break down coffee oils, in the same way a random household product isn't formulated to dissolve limescale.
The fix for both is simple:
1️⃣ Clean the brew chamber with a purpose-made cleaning tablet
2️⃣ Descale the water lines and pump with a dedicated descaling solution
Your machine needs both, on their own schedules, done properly.
