For in-between up-keep, I use some quick detailer type of spray and wipe solution without needing any water.
If it's really dirty then I use the traditional water hose, soap, and sponge action. Normally I will shower the water on the bike like how it would be if it was parked out in the rain. I avoid spraying water from a bottom-up angle to avoid water getting into places it shouldn't normally get it (if it was parked out in the rain).
For a nice popping finish I use the Maxima SC-1 after it's all clean and dry, it can be applied onto every surface just keep it away from the tires and your seat because it will make them super slick.
