I'm Steve, I sell Sodium Chlorite and Sodium Chlorite Solutions. Nice to have you here.
I have dropped too many links here as it is, so I sent you a PM
There are alternatives to the Humble protocols. There is a lot of info in these threads about other uses, and also discussions on 5% NaClO2 vs 22.4%. ClO2 is a great deodorizer, and can kill mold and bacteria, and keep your ducts clean also. (if you have them)....
Hit me up in PM or give me a call. I'd be happy to discuss your particular application.
