How do they clean the stadiums after games?

Question

I look around AT&T Park(SF) and notice theres so much trash littered around the seats. I wonder how do they clean it up so fast, especially when there's a day game following a night? Do they work overtime? What about the lights, they usually turn them off seconds following a game?

Answer 1

they work overtime and they have A LOT of people working to clean it. I now its hard to believe but its true.

Answer 2

they sweep everything having many people doing it

then they prolly mop and disinfect

and have solar power lights?

Answer 3

They hire many people to clean it up.  They turn the lights off the save electricity.....then turn it back on when another game starts.  Hope this helps =]

Answer 4

Row by row and section by section, they start at the top and work there way down.  There is no trick, just old fashioned hard labor.
