No one said it was specifically designed for reptiles. I said that it was marketed to reptile keepers, commercially pushed on them. That's not to say it's reptile keepers exclusively.
I'm not sure if it was deliberate or unintentional, but your description of chemical and mechanical cleaning is misleading. With Mr. Corona making this issue topical, it's worth knowing that washing with soap/detergent and water is more effective than F10 (or hand sanitiser) unless you're going to soak the item (or skin) for an extended period, longer than you would spend washing yoir hands or an item.
'Mechanical cleaning'/not using chemicals shouldn't be confused with using soap or detergent. These work to remove things as well as denature them. Disinfectants primarily or exclusively work by denaturing (as opposed to removing) things. For example, if you use hand sanitiser the germs are still on your hands, but they're destroyed. Washing with soap removes them from your hands so even if they are not destroyed, they are removed. F10 requires more time than people typically give it to work, making it generally useless as used by regular untrained hobbyists. Washing with soap or detergent is generally effective.
F10 may be appropriate for vets who know how to use it and have unreliable vet nurses who can follow orders but are as stupid and unreliable as typical vet nurses (let's be honest, any of us who has spent much time around vets knows exactly what I'm talking about), but especially for hobbyists, F10 is pointless and generally counterproductive due to providing a false sense of security/sanitation.
