I hate these wheels I don't think I've ever got them completely clean since I've owned the bike.Good suggestions here but the best so far is buy a set of SG wheels.Although a toilet brush, a jack and a leaf blower might be cheaper.
I have some street glide wheels. I just took mine off the street glide and put the ultras HAHAH. Crazy how people can be so different. I think the SG wheels ae ugly.
I take off the saddlebags and use a long-handled dish brush with my regular wash blend on my chrome knuckles wheels. Scrub, rinse, move the bike, repeat. Hit it with a leaf blower then wipe down with microfiber. Not really a tough job - maybe 10 minutes tops? Would be easier putting the bike on a stand but I don't have one.
maybe 10 minutes tops? ... It takes me 10 minutes to get the washing crap out :>)
