Lime is of great value in a privy or outhouse. The type used for outhouses is calcium hypochlorite, or Ca{ClO}2. This unrefined white powder, made by running chlorine gas into slaked lime–which is the lime used by masons–is often mistakenly called “chloride of lime.” It is the best type of lime to use for outhouses as its germ-killing properties are identical to those of household bleach. There are two ways to use lime in an outhouse–on the walls and in the pit. Remove accessories from the outhouse. These items may include a waste basket, toilet paper, tissues,a bucket of powdered lime and air freshener. Stir the lime and water together in a bucket until you have produced a thin paint-like mixture. Paint the interior walls of the outhouse with the lime and water mixture, using a large brush. Do not paint the seat as the mixture tends to crack and chip after a while. Allow the walls to dry thoroughly before moving the accessories back into place. This process is called whitewashing.
