Puro espresso machine cleaner removes the residual build-up of coffee solids and oils from screens, valves, and tubes of brewing groups. This is important to quality coffee because a dirty machine will create dirty-tasting coffee. Backflush your machine following the directions below (and on the label), and soak the portafilter baskets (not the handles) in a solution of very hot water and Puro.
Thoroughly rinse groups and portafilters. Always re-season your machine and portafilters by making and discarding one espresso on each group. Espresso machines should be cleaned daily.
How to Backflush
- Insert blind filter in portafilter and add up to 1/2 teaspoon (3 g) of Puro Caff Powder.
- Insert portafilter into group head. Activate brew cycle for 10 seconds. Stop 10 seconds. Repeat 5 times.
- Remove portafilter and activate brew cycle and rinse portafilter in stream of water from group head.
- Re-insert portafilter without cleaning powder. Activate brew cycle for 10 seconds. Stop 10 seconds. Repeat 5 times.
- Replace blind filter with standard basket. Make a cup of espresso to remove any traces of cleaner.
- Discard espresso - do not drink.
