Hydrogen Peroxide is not on these lists, except as an additional ingredient in a few of the products.

Hydrogen Peroxide does appear to be effective, tho' I didn't read at what concentration:
[Virus inactivation by hydrogen peroxide]. - PubMed - NCBI
PacMed Primary & Specialty Care Medical Clinics - Seattle

[Virus inactivation by hydrogen peroxide]. - PubMed - NCBI
H2O2 in a 3 percent concentration inactivated all the viruses under study within 1--30 min. Coronavirus and influenza viruses were found to be most sensitive.

Tec Clark just released a new podcast about this very subject.

Some claim to have experienced an allergic reaction to Madacide-1 residue left on gear; and one of the common methods for its use, at least in that podcast, involved an initial fresh water rinse of regulators after use; a dip in a 10% Madacide solution; and subsequent storage of that gear without any further rinse. Eh, no thanks.

I'll stick with Virkon-S and Steramine, with lots of rinsing . . .

The Star San manufacturer's website doesn't provide any information about kill spectrum or dwell time, information typically provided about disinfecting products, so I don't know that I would consider it reliable for disinfecting purposes (though it's been reliable for me in home brewing). Amron International sells Sanizide, which is a quaternary ammonium chloride based disinfectant. If you really want to be assured of a sanitary regulator, something like that is probably the way to go.

Personal gear, why? Just rinse. However if you are a shop owner/operator that rents gear then maybe use Madacide or something similar. However its probably gone just like the TP is at this point

Personal gear, why? Just rinse.

A BIG problem is rinse tanks. Best to think of them as for salt only, and to independently afterwards disinfect, and then in fresh running water rinse the disinfectant off. Many folks NEVER use a communal mask bucket. Now that extends to communal reg buckets.

When I dove in India I refused to use the communal rinse tanks after diving. I lugged my gear back to my room and used the shower to rinse everything off exceedingly well.
