Anti-foaming agent, or defoamers, prevent a solution from generating foam. Foam can prevent you from being able to see the detergent and what it is cleaning. Excess foam can also get in the way when cleaning. Add anti-foaming agents to your detergents to prevent your washing machine or dishwasher from overflowing. Purchase anti-foaming agent from a home improvement or janitorial supply store. Because concentrations vary from agent to agent, always consult the manufacturer's instructions when determining how much to add.
