Bleach: Why you should NOT use it

• Bleach is a chlorine-based corrosive substance; even small amounts can harm our health, particularly our respiratory system.
• Bleach is not recommended for removing mould as it only kills the surface mould. 
• Bleach is a dangerous substance to have in our homes. It can become deadly if mixed with other substances such as ammonia, vinegar, drain cleaners, or hydrogen peroxide.  A shocker is that if it is mixed with dirty water or water high in organic compounds, it can give off chloroform gas. 
• Bleach is one of the top poisoning toxins of children worldwide.
