Ka-Kleen エスプレッソマシン用クリーナー

My machine had been pulling slightly bitter shots for weeks, and one proper deep clean with this powder completely fixed the flavor. A single scoop in the backflush basket foamed up nicely and lifted all the grime, leaving the group head spotless. This is now a permanent part of my Sunday routine.

I’ve been using this every two weeks for the past couple of months and it dissolves the coffee oils so thoroughly I can actually see the difference in the water flow. One packet per cycle leaves the group head sparkling clean.

My espresso machine had been tasting a bit off, but after one cycle with this powder, the difference was night and day. It really gets into the tight spots.
