Looks like a backyard, not a Marathon station. Need pics, they’re all different

thanks for helping me really trying my best to save up for a new pressure washer ill add u if I have more questions

What all do they want cleaned? Pads, store front, canopy, islands, sidewalks, or what?

Don’t get too excited about this. These stations historically cheap.

what equipment are you using, what chems, and how long do you think? Do you have a big enough water tank? I wont have an answer but I know there needs to be more info to answer.
