Carpet removal completed!!!

Yesterday I spent the better part of 7 hours removing the carpet from the 3rd (and last) bedroom. (see pic above)
I had a real surprise when I pulled up the carpet padding: there were black blobs of carpet pad stuck to the floor, it was a gooey tar-like mess! The darned floor looked like spotted leopard!
Some quick internet searching on how to remove this stuff yielded one fellow's post on how he used Resolve carpet cleaner to remove the goo. I checked my cleaning cabinet and found a bottle of Hoover hard floor cleaner that I had received with my old Hoover Steam-Vac.
First, in order to get some of the thickest goo off the floor, I used my mop-brush to scrub as much of it off as possible. Then I wet an old rag, poured a little of the hard floor cleaner directly on the rag and squeezed it out til it was damp. (It's important not to get the floor very wet, as this could warp the wood or raise the grain.)
Then I went to work on the floor, and this stuff DID take off the goo, but it took me an extra hour or so to get it clean enough to actually start removing staples and tack strips.
I wondered why this floor had carpet padding stuck to it and the other two rooms I'd worked on did not have any goo. I concluded that one factor was probably that we heat this bedroom in the winter but the other two bedrooms were my girls' rooms and since the girls have left home, I don't routinely heat those two rooms anymore. The carpet goo was worst in the areas of our bedroom floor that had no furniture over them. Our heat is radiant ceiling heat, which is the ONLY heat that is heavier than air. So the heat sinks to the floor. I think that had a big effect on the carpet pad's sticking and decomposing.
Another thing I discovered about removing staples is that when using the Stanley pry tool to pull out staples, it's helpful to get the fork of the pry tool positioned squarely under the staple, and then put a finger over the staple to hold it in position, as you remove the staple by using the pry tool to pry upward. This stabilizes the staple enough that you can pull over 90% of the staples out using the pry tool alone.
I also tried was the carpet sliders to move a cabinet and our bed. They work GOOD! I could have never moved the bed without them, frankly.
