A unique formulation that kills foam quickly and effectively in vacuum systems of carpet and upholstery cleaning equipment. This defoaming agent breaks down foam and eliminates the possibility of it being sucked through the vacuum motor of your machine. If that foam were to be sucked through the motor, your warranty would be null and void on the unit. Using a defoamer is essential part of the recovery process. If you were looking for smaller containers of defoamer, please check out our complete line of liquid defoaming solutions.
