I believe at one time (perhaps still) it was commercially available as Dowicide 50. However, before thinking too seriously about this approach I would be concerned about the toxicity of the chemical. Chlorine dioxide is moderately toxic by inhalation (the exposure limit is 0.1 ppm and the IDLH is 10 ppm), it has experimental reproductive effects and there is mutagenic. It is an eye irritant and a powerful explosive sensitive to spark, impact, or rapid heating. It is also a powerful oxidizer. Concentrations greater than 10% are explosive. Likewise, it is explosive when mixed with various hydrocarbons, as well as sugar, and (I believe) organics such as dust. It also reacts with water to form HCL fumes. In other words, while I realize that it has been used in the past, I really can't see any reason that we would want to use it these days. Drying, control of RH, and manual cleaning using HEPA vacs still seem to be the far superior means of dealing with mold. Best, Michael Trinkley, Ph.D. Director Chicora Foundation, Inc.
