How should I clean the 58, and how often should I do so?
To clean your press stand: Simply wipe down with a clean cloth after use. Avoid use of cleaning agents or chemicals.
To clean your brew head cylinder: Simply remove the plunger (use your lock-in stem to pull/wiggle it out the top of the cylinder) and wipe down the inside. Pull a water only shot to clean further.
Clean as needed or as desired: The puck screen will help prevent coffee grounds from entering the cylinder, so it will stay quite clean after each brew!
For the Flair 58: Do not run under sink or you risk water getting to electrical components.
To clean your plunger: Rinse with water and dry with a clean cloth. Afterwards, it is good practice to lightly lubricate the o-rings to re-encourage smooth travel, as you will have rinsed away the natural coffee oils that built-up. Simply apply a light application of food-safe oil and wipe away the excess.
To clean your puck screen: Simply rinse with high-pressure using your sink sprayer after use. An ultrasonic cleaner works great for deeper cleans, too, if you have one on hand!
To clean your portafilter: Knock out the puck after use and rinse under the faucet until clean.
