Well here are the before pictures.
The shelving unit is in the dump.

The floors are very badly stained. I used 1 Gallon of Acid on it yesterday. I cleaned it a second time this morning (don't have the pics uploaded) and patched some small cracks in the cement. It's been drying all day and I will paint tomorrow. I'm not going to get all the junk off the floor so I hope that the 2 washings will prevent the paint from lifting. I used a lot of acid.
