For me, just wash with plain water (save $$ for the shampoo,
soap water make bike rusting fast), then wipe with a dry
cloth.
Polish the chrome part with Autosol, but dont polish too much, the
chrome very thin (especially the plastic part).
For the oil stain, wipe with cloth (spray with abit WD40).
No waxing ah, still new mah... if wax, more shinning....
