Once you pull a valve (black or gray) open spray the shaft. Close it and do it again. I did mine probably 4 or 5 times before I noticed a difference. I did one valve and closed it & then did the other. I switched back and forth, allowing a few minutes between each one.
I used a can that had a long tube so you can get the spray where you want it. I used WD-40 Dry Lube PTFE Spray
