BEST Grease Cleaner for Wheel Hubs?

Hi friends!

I am attempting a first time repair on a front wheel hub and have already went through the process of taking everything out, the rods and the ball bearings.

And now I'm curious to know what the best method is to clear up and prep the wheel hub for installation?

Also, can I get a suggestions on which ball bearing are great? (Decent priced)

Thanks
