How to properly degrease the freehub engagement ring pressed in to the hub without spraying the degreaser (brake cleaner) on to the cartridge bearing seal? Usually/previously cleaned the engagement ring with q tips but since it's impossible to clean all of the edges in this way then there is no other choice but to soak it in brake cleaner instead. One option is to smear some silicone sealant around the bearing seal so that it can be easily removed. Another option is to stick a washer on top of the bearing using the same silicone sealant, but since sometimes it can result in strong adhesion then it might lift the seal upon removal of the washer.
