I have been using the Mr Clean auto dry for a couple of years also, even on my second unit now, have washed cars, trucks, 4-wheeler and several different bikes, this is the way for me, it is quick and easy, I just put the bike in the sun for a little while after washing and tries spot free in about 15-30 minutes. Also on the speakers the last time I washed I forgot they were even there and sprayed water directly into them....NO ill effects from it as the speakers in these bikes are water resistance, I could even watch the water slide right off of them.
