Cleaning Snow and Salt

First off, I'd like to say I've been cleaning here for years, so I've been through this multiple times.

However, this company has grown in staff and clients over time.

As us Midwesterners know, the snow and salt can be overwhelming to clean effectively. I know to use vinegar and wring out the mop a lot.

My question is, if you're doing a large building by yourself, how on gods green earth would you get through everything in one night? I mean, the floors everywhere are bad. Tons of offices, also bathrooms and kitchens to clean. Large spaces, all full of garbage and whatnot.

In my opinion, this is easily a two person job if they want it as clean as possible. I'm not going to stress myself out anymore and work as hard as possible to clean every square inch.

Would you skip one task entirely? (Wiping down desks, as an example.) Or would you let the recycling/garbage accumulate until it's full? How do you do your job currently without burning yourself out in one night?
