Just completed a bit of maintenance on my GPP. Did my regular chemical backflush, removed the group seal and screen and scrubbed the mushroom clean. While at it and with the machine unplugged and cold I used some mild auto polish to buff out some light scratches on mainly the drip tray. Noticed some scratches on the plastic cup warming tray surround and used some Meguiars motorcycle plastic polish on it and the hopper on the Mazzer Mini. Came up a treat
