A bad case of mouse droppings. And dust. And seven years of not being tuned. And a rather warped finish.

It's now in pieces, so we can clean the parts we can reach without taking off the string. Unfortunately, the keys got rather too well cleaned when my housemate decided scrub them - I did look rather askance at that, but assumed she knew what she was doing as she's taken pianos apart (and reassembled them) before. So the rough edges in the hole that fits over the pin have expanded so that the keys stick even worse than before. I'm hoping a drill bit and some judicious sanding will rectify that.

Still, hooray for Freecycle!
