It can be used in conjunction with a mop, bath towel or dish towel to clean bloodstains from surfaces. As of build 38, rotten corpses will make the player feel ill and sad, however blood splatters do not, meaning that cleaning blood is purely cosmetic. If the player has both a bottle of bleach and a mop, bath towel or dish towel, when right-clicking a blood splatter, the option "Clean Blood" will appear.
Bleach is a poison , therefore if the player drinks a full bottle, they will become sick and unhappy, followed shortly by death. If the player is zombified, they will still reanimate as a zombie.
Bleach can be added to any completed meal with at least 3 ingredients, where spice is not considered an ingredient. Upon adding bleach to a meal, the icon will not be displayed on the tooltip, meaning it can be given to other players without them knowing it is poisoned. However, if enough poison is added to the meal, a poisonous skull icon will appear over the meal's icon. Therefore, the player must be cautious when aiming to poison a fellow survivor. If a poisoned meal is consumed, the player will begin to see signs of sickness and begin to lose health. This will not always kill a player, so long as they have not consumed too much of the poison.
