I use a garden hose, Simple Green, a Park Tool Bike Cleaning Kit & rags & an old retired Cycle Ops trainer frame, with out the resistance mechanism.
Spray it with water, spray the Simple Green on drive train, brakes, etc. use brushes from cleaning kit, rinse. Fill chain cleaner with Simple Green & clean chain, rinse.
I dry as much as I can with dry rags, use my shop air compressor to blow the water out of places it is hard to dry from, let the rest air dry. This also includes flipping the bike upside down to let any water drain out of the frame.
After it is dry I lube appropriatley.
I clean the bike at least once a month in the spring, summer & early fall. More often if needed.
