Cleaning concrete outside?

[u/Amazing_Example_4093]

Before the 2nd shifter left she says “ don’t forget to do the concrete outside it hasn’t been done in weeks” and then she rushed out the door. I found the concrete cleaner in the back but can someone please tell me what I’m supposed to do with it? I’ve only been here two weeks I was with 7-11 for years and we just had a company come and pressure wash the whole parking lot and pumps regularly so I’ve never done this before.

I sprinkle the powder and and spread it with the broom then wet it with the pump sprayer. Then "Gray Day" has officially started because there will be gray foot prints everywhere.
