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.
What Does It Mean to Desecrate the Flag? The US flag is sometimes burnt as a symbol of protest, often against the policies of the American government. The flag can also be used in other symbolic ways, such as wearing it in an offensive manner or, as in this case, displaying it upside-down. While burning a flag is actually an action, a non-verbal act makes a similar statement. And it is protected as symbolic speech under the First Amendment.
