Always found it hard to clean your grouphead with those nylon bristles which tend to get sticky over time if you don't clean the coffee oil off?
This tool is shaped like your coffee machine portafilter and works exactly the same way too - except it cleans!
Instructions to use:
1) Scoop some espresso cleaner powder or use one sachet of puly caff and pour it on top of the white silicon
2) Fit your brush into the grouphead through the same grooves where your portafilter fits into
3) Swing the handle from left to right to clean the grouphead
4) Enjoy your spanking clean grouphead free from coffee oil!
