While Flight Attendant components can withstand pressure washing and submersion, each component should be treated the same way you would treat ball bearing-equipped components such as a hub, headset, or bottom bracket. That is, avoid blasting water directly at the seals on the modules or at junction points between component assemblies.
Make sure to remove the SRAM AXS batteries and install the red battery blocks into the fork Control Module and Rear Shock Module before cleaning.
