I bought a hypochlorous acid water generator. To disinfect surfaces, food pretty much everything. It makes 300ml in 8 minutes. My question is how long is it good for as a disinfectant? I thought I would make a few gallons of it (water and salt) and put it into spray bottles and give a couple of bottles to each of my family households to disinfect with. Is it still an effective disinfectant 2 days later, a week later, 2 weeks later...?
