Box of detergent (Fallout 3)

 is an item in Fallout 3, useful only as Rock-It Launcher ammunition. It is found all over the Wasteland and can be found in your Megaton house when you buy an Wasteland Explorer Theme or Vault Theme. There are around 40 Boxes of Detergent in Gold Ribbon Grocers, which are used to make a rube goldberg machine.
