Ever since I began waxing my chains (3 years almost now) , my bikes appear almost surgically clean to others. I wipe down my frame tubes with "tub-o-towels" and also remove my wheels and spay them in the utility tub with a dilute simple green spray an a soft brush after any wet rides. I use stainless steel appliance wipes on my titanium bike frame after cleaning the dried worms off with the tub-o-towels wipes. The stainless steel appliance wipes have a slight oil in them which pleasantly details oxidized plastic and such.
