hmmm. short of being packed full of sand/dirt, i dont think i would do alot of cleaning. i worked on a seismic retrofit job in san francisco. the early part of the project included digging down and enlarging the footings. i found some stuff leftover from the 1906 earthquake. as a matter of fact, we had a full time arch students with old school maps. they could tell us this was the "so and so" property. it was cool. i found bottles, old pipes, etc. the "holy grail" for me was antique marbles. i found 8 or so. we ran across 4 priveys (polite way to say outhouse). back in the day, folks would toss all sorts of stuff down there. they were taped off, and it was illegal for us to pull stuff out.
