Soap and water when washing hands. To deal with small scratches and abrasions cape cod is good for polished services, and either Scotch-Brite or Bergon blocks for brushed services. Occasionally I will take the bracelet off the watch and place it in ultrasonic cleaner, and then lubricated bass bring it down with WD-40 and working it in then washing it off thoroughly with soap and water again. Side note never put the watch head in ultrasonic cleaner and never spray WD-40 on the watch head
