I'm on vacation in California taking care of my dad's 10 acre farm while he is out of town. The resident fauna include 2 watch llamas and a small flock of Barbados sheep (self-shearing). When I arrived the flock had 11 sheep - now there are 16. If you're counting (and I am, every morning), that means that 5 new sheep have appeared. Four of them were born in the space of 2 hours a week ago last Saturday in the 107 degree heat of the afternoon. Birth is a messy business, and in the end I sacrified not one, but 2 white t-shirts to the process.
After the biology had settled down and was nursing happily, I turned to chemistry to get the stains out of my shirt. My dad (experienced in these matters) advised no bleach, and soaking in a strong salt solution. Why no bleach? Bleach is an oxidant, and "removes" (or at least decolorizes) many stains by oxidizing the carbon-carbon double-bonds which are responsible for the color. The red color of blood comes from the oxyhemoglobin. Oxidizing the iron in the hemoglobin produces iron oxide - aka rust - not necessarily an improvement on the front of your t-shirt.
One of the new arrivals.
