This is the easiest espresso maker to maintain. No descaling, backflushing, or anything like that.
All it needs is a wipe down of the stem and brew cylinder o-rings and a very light coating of food-safe silicone (Flair recommends Dow-Corning 111 silicone compound grease) to reduce friction, improve sealing, and keep the rubber supple.
1. Remove the gauge/plunger stem (with this latest version of the 58, it’s just held in by the small pin with o-ring).

3. Pop brew piston out of the brew head cylinder bore, remove o-rings, wipe any residue from brew head cylinder bore and piston, apply light coat of 111 to o-rings, and re-install O-rings.

4. Pop piston back into bore, re-install brew head into frame, snug up the set screw, put stem/gauge assy back in, and you’re done!
Takes maybe 15 minutes, and that’s if you take your time doing it!
