I tried Perfect Solution this year based on your recommendation and I agree that it does great job; I just want to add that I found the rinse to be critical. Before trying it on reel bearings I did a test clean on a bearing I robbed from a computer cooling fan and found that after rinsing and drying, the bearing was reluctant to move and when I did get it turning it felt extremely rough. I removed the shields (I am someone who prefers not to mess with the shields, even though cleaning is faster without them) and found that there was a gummy film on all the bearing innards. It rinsed away with hot water and after that the bearing was, as advertised, Perfect. I went through the whole process again with the same bearing and found that again, after rinsing and drying, the bearing was again semi-seized, and opening it up revealed the same gummy film. After rinsing it out I went through the whole process a third time but after rinsing it off I immediately put it in a jar of plain old hot water and let it soak for fifteen minutes, agitating gently a couple times. I changed the water and soaked it a second time, dried it with a hair dryer, and finally had a free-spinning bearing.
So, to anyone who hasn't tried it, I concur that Perfect Solution is a nice, effective alternative to solvents, but don't skimp on the rinse!
