Clean it best you can, rinse it out, toss it in the dishwasher? I have a partswasher available. Packing is best done inside a ziplock sandwich bag. Grease and bearing go in, shove grease in one edge 'till it comes out the other all the way around. That's the best bearing packer I know of.

I sold bearings for many years. IMHO, SKF are arguably the best, but to be fair there isn't a great deal of difference in quality between the various "better" brands these days. My personal preference is still SKF, but any reputable brand such as NTN, NSK, NACHI, KOYO and FAG will be of consistently excellent quality.
SKF front wheel bearing hub assemblies - any good? - Bob .
