Not familiar with citrus cleaners for bearings, I tend to avoid household or water based cleaners. They can actually leave residues, and cause poorer performance, but like I said this is just my experience. I have had a couple bad ones but most of the time cleaning solves it. I use a shot glass sized container with a lid so I can give it a shake, sometimes the tiniest little fibers is all it takes to mess it up but it’s not broken . Sometimes for me perfectly working bearing sounds great, nice and smooth then within one throw all of a sudden is screeching, loses spin time, sometimes becomes responsive, that’s when I clean it. When it’s been an out right defective bearing it usually never spun right from the beginning and cleaning made no difference then yeah I toss it.
