Any dirt you flush off of the bikes with a stream of cool water will not be around to be rubbed against the delicate finish with a soft cloth or sponge. So, rinse off the bike with cool water and let it sit for a few minutes so the water can soak into the grunge. Then rinse the bike again. You’ll be surprised how much dirt flows off in the second rinse cycle. Now, your bike is ready to be washed.
