A degassing chamber for an ozone solution system includes a cylindrical housing defining a cavity. A mixture of water and ozone gas is delivered to the cavity, the mixture containing excess ozone gas. A cylindrical float is positioned centrally within the cavity to rise in accordance with the mixture column within the cavity. A piston is connected to move in accordance with the float. When the mixture level rises above a threshold, the piston the piston moves upward and seals an ozone outlet. As a pressure of ozone gas in the degassing chamber increases, the float is forced downward causing the piston to open a channel to an upper ozone outlet through which excess ozone gas is released. After removal of excess ozone gas, a mixture of water and ozone gas is output from the degassing chamber which is suitable for use as a general purpose cleaner.
