Just spray it on a cloth or directly on the bike. I would try not to get any on the brake rotors though or in the pads.
That's all there is to it. I got this stuff at Canadian Tire and I give it the thumbs up.

Just used this stuff to clean my car. Worked great. Dunno if it was the wax additive or the fact that I polished it with a Shamwow but it is shiny and looks about as awesome as a stock civic can look ;-)
