Abstract
A method of treating a product or surface with a reactive gas, comprises producing the reactive gas by forming a high-voltage cold plasma (HVCP) from a working gas; transporting the reactive gas at least 5 cm away from the HVCP; followed by contacting the product or surface with the reactive gas. The HVCP does not contact the product or surface.
