Ka-Kleen 濃縮咖啡機清潔劑

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.

It dissolved the coffee oil residue on my group head after just one backflush, which was a pleasant surprise. I do wish the instructions were a bit clearer about how much to use for a single boiler machine, but the results are solid.
