Three different jobs: oils, minerals, mess
Coffee oils foul group heads and baskets — that’s detergent (Cafiza/Puly) with a blind basket. Minerals from water need a descaler on the manufacturer’s schedule. Multipurpose tablets can help with light residue but don’t replace a proper backflush powder on semi-autos. A brush and knock box keep the daily mess from becoming a weekend project.
A cadence you can remember
Daily: wipe steam wand, purge, knock pucks, brush the basket. Weekly (or every 30–50 shots): detergent backflush if your machine supports it; soak baskets and portafilter. Every 1–3 months (water-dependent): descale per the manual. Skip inventing chemistry — match the product to the job.
Why taste dies when you skip cleaning
Rancid oils taste bitter and mute sweetness long before the machine “fails.” Descaling late shows up as temperature instability and weird flow. If shots suddenly taste hollow, clean before you buy a new grinder.
Our kit shortlist
Cafiza or Puly + blind basket for backflush machines; a dedicated descaler; a grinder brush; a knock box. Tablets are optional backup for drip/super-autos — not a substitute for detergent on a Gaggia or Silvia.
