Cheap, safe, effective DIY disinfectant that I wish I knew about earlier: hypochlorous acid aka HOCl aka "electrolyzed water." Kills covid (all variants), mpox, RSV, norovirus, flu, bird flu, all flu, mold... More effective than bleach and also safe enough to be used on skin and inhaled into your lungs. I use it as nasal spray and mouthwash every time I leave the house, in addition to a bunch of other things I use it for.
For like 20 bucks, you can clip some alligator clips to a battery and two pencil graphites, stick the graphites in some water mixed with a little vinegar and salt, and make your own HOCl.
