I know grease questions create a lot of debate but I'm curious. I recently bought a campy record threaded headset and saw that the ball bearings and the cages already have grease on them, white lithium grease what I'm guessing. I know it's good practice to grease the headset races etc liberally but I don't have any white lithium grease or "special campy grease" lying around, I only have some marine grease and some Phil's. Do you know mixing greases together will cause any trouble? Should I use some sort of degreaser to get the grease on the ball bearings out and regrease them and the races during installation?
