Not too much work to polish them at all.....i clean them up real good with engine degreaser or a strong degreaser like purple power, then polish them with aluminum polish on a dremel with the small buffing wheels you can get for them. Takes about 10 minutes to do one wheel, which isnt too bad. Sometimes ill just clean them with the degreaser and be done with it, which does the job just fine but i like em nice and shiny lol. Lately iv been buying black anodized wheels from Tru Center or Douglas Q+, they are very nice quality wheels and easy to clean, no polishing needed. Those will be the wheels i buy for next year, all black.
