The Teflon brush is the most common tool used to maintain espresso machine brew groups. It gently yet efficiently dislodges grime and coffee residue accumulated in the gap around the brew group.
The Teflon bristles are both flexible and strong, and are very easy to move around to properly clean the brush. Our trick: run the brush under the machine's hot water after use to give it a good rinse.
A weekly brushing is sufficient for a daily-use residential espresso machine. For commercial machines that get a lot of use, we recommend daily brushing.
