In my book, Frederick Douglass for Kids, you can make a type of laundry soap to wash spots off dirty socks. This recipe is adapted from a recipe found in the book, The House Servant’s Directory by Robert Roberts.

Here is the original recipe as found in his book:

Take half a pound of crude honey, the yoke of a new laid egg, and the bulk of a nut of aromatic salt, then mix all well together, then put some on the spots; having left it there awhile, then wash it off with clean water, and the spot will immediately disappear. This receipt is of great importance to servants that have the care of their master’s wardrobe, and in many other similar cases.
