Abstract
This invention relates to an improved chlorine dioxide solution or liquid mixture containing a phosphate and, as well, as to a composition for forming the chlorine dioxide and phosphate liquid mixture. This improved chlorine dioxide solution is used to clean and/or sanitize without causing corrosion. The corrosion nature of the chlorine dioxide solution is lessened due to the addition of phosphate to the composition.
