1. A stabilized two-part disinfecting system comprising a first part and a second part adapted to be mixed to yield an aqueous disinfecting composition, wherein:
- the first part comprises a non-esterifying inorganic acid, or a non-esterifying organic acid selected from the group consisting of organic sulphonic acid and organic phosphonic acid, or a mixture thereof, and an alcohol-containing humectant or antifreeze selected from the group consisting of a monohydroxy alcohol, a polyhydroxy alcohol, an alkyl ether of polyhydroxy alcohol and mixtures thereof; and
the second part comprises a salt of an organic carboxylic acid, a metal chlorite and a base, wherein the base is present in the second part at a concentration sufficient to adjust the pH of the second part to a value ranging from about 9.0 to 11.5;
and whereinthe non-esterifying inorganic acid or non-esterifying organic acid is present in the first part at a concentration so that, when combined with the second part, it is sufficient to convert at least 50% of the salt of the organic carboxylic acid to its corresponding acid form and to reduce the pH of the disinfecting composition to a level below about 5.0;
the alcohol-containing humectant or antifreeze is present in the first part at a concentration so that, when combined with the second part, it is present within the disinfecting composition at a concentration ranging from about 2% to about 40% by weight;
the salt of the organic carboxylic acid is present in the second part at a concentration so that, when combined with the first part, it is present within the disinfecting composition at a concentration ranging from about 0.25% to about 10% by weight; and
the metal chlorite is present in the second part at a concentration so that, when combined with the first part, it is present within the disinfecting composition at a concentration ranging from about 0.005% to about 1% by weight.

Abstract
A stabilized two-part disinfecting system comprising a first part and a second part adapted to be mixed to yield an aqueous disinfecting composition. The first part contains a non-esterifying acid and an alcohol-containing humectant or antifreeze, while the second part contains a salt of an organic acid and an optional metal chlorite. Methods for making a disinfecting composition by mixing the two-part disinfecting system, as well as for disinfecting substrates by contact therewith, are also disclosed.
