So does bleach. Neither one is a proven treatment for COVID-19 in vivo though.

Almost all in vitro (i.e. in a Petri dish) results are of limited value. A lot of things kill viruses in vitro, including air and water, but aren't actually treatments inside people. Until they do at minimum a phase 1 trial (to show basic safety) and have even draft results showing efficacy, I'd hold off on assuming this is relevant to the discussion /at all/.
