Remove all the furniture, and spray the floor with a hardwood flooring cleaner or your own mix of 10 parts water to 1 part white vinegar. Gently wipe the floor with a terry-cloth mop or a towel wrapped around a mop head. Close the windows and doors to keep dust contained in the room you're sanding. About $200.
Upside Down Flag. Flying the American flag upside down is an officially recognized signal of distress. Here is the relevant part of the US Code of Laws regarding how to fly the flag when in distress: THE UNITED STATES FLAG CODE Title 4, Chapter 1.
When the flags are flown from adjacent staffs, the flag of the United States should be hoisted first and lowered last. No such flag or pennant may be placed above the flag of the United States or to the right of the flag of the United States (the viewer's left). When the flag is half-masted, both flags are half-masted, with the US flag at the mid-point and the other flag below. 5. When the flag is suspended over a sidewalk from a rope extending from a house to a pole at the edge of the sidewalk, the flag should be hoisted out, union first, from the building.
