In a five-gallon bucket, mix 1 oz. -- two caps full of the 32-oz. product bottle -- of Optimum No Rinse Wash & Shine into two gallons of distilled water. Put 6-12 -- depending on how dirty the car is -- microfiber wash cloths/pads such as these into the water. Have 4-6 microfiber drying towels on hand. Starting at the top, wash a a section of the car, discard the wash cloth/pad into a laundry basket/bucket (I'm not counting this as a second bucket!), and dry. Repeat on the next section. As compared with the two-bucket no-rinse technique, this saves the time and effort of rinsing the wash mitt/cloth in a second bucket between washing sections of the car, but with the expense of buying a bunch of wash cloths/pads.
