    Sigh Please don't just repeat something you may have "heard" form
    someone else. Do a bit of research and at least give proper
    information 

    1- Bleach and Ammonia DO NOT create mustard gas. The create Chlorine,
    a very different gas, although Chlorine is dangerous as well it is
    not in the same class as mustard gas. See 

    http://www.chm.bris.ac.uk/motm/mustard/mustard.htm 

    For more info on bleach and Ammonia Google it or ask anyone with
    basic chemical training. 

    But for those who can't here is an excerpt for the non technical
    person... 

    From: http://www.bbc.co.uk/dna/h2g2/classic/A795611 

          That warning is there to protect you. Household bleach has a
          chemical formula of NaOCl - that is, one atom each of sodium,
          oxygen, and chlorine. Its chemical name, for the curious, is
          sodium hypochlorite. Ammonia has a chemical formula of NH3,
          that is, one atom of nitrogen and three atoms of hydrogen. When
          these two compounds are combined, the following reaction takes
          place: 

          2(parts) NaOCl + 2NH3 --> 2NaONH3 + Cl2. 

          Do you see that Cl2 on the right hand side there? This means
          one part chlorine gas, made up of diatomic (two atom)
          molecules. It also means that the chlorine gas has been
          liberated from the bleach, and is quite capable of causing you
          harm when inhaled! 

    Now on to the second problem with the statement "at Radio Shack, one
    guy there said that floor waxes have bleach as a constituent element"

    I am happy to find that people who are experts on dangerous
    materials can be found at the local radio shack. Can I suggest a
    local University Chemical department as possibly a better place to
    find Accurate information? For a not too technical description of
    what a wax is see http://en.wikipedia.org/wiki/Wax 

    However I will give that there is no telling what a maker might try
    to mix in a commercial product despite the fact that Bleach is a
    water based product and by definition wax is non-miscible (does not
    mix) with water. 

    Anytime one is working or contemplating working with a product today
    has no excuse given the internet and legislated availability of MSDS
    information not to research what they are working with. The other
    point is that frequently the "public" usage of a name differs over
    time and locale (Thinking back to the discussion we had here on
    Ether last year). Therefore not only should you try to find the
    information on what you are using, but you should also try to
    determine what the original recipe called for. As an example here
    (Using wax as a resist) I am guessing that the technique calls for an
    older organic wax like beeswax, not a modern synthetic which could
    cause problems during and after the fabrication. (LOL just thinking
    of the effect of putting a silicone based wax on something and then
    trying to remove it with common cleaners...)
