Very weird not to use dishwashing gloves for that. It's like taking a photo of yourself as an example of brushing your teeth and forgetting to use toothpaste. It's just so strange that it's hard to imagine it wasn't done on purpose.
Curious as to what difference gloves would make in this specific situation according to you? You're washing everything with soap to "disinfect" it. Your bare hands will also be full of soap. Wouldn't they also get disinfected? What am I missing?
Washing up gloves are there to protect your hands from the heat of the water. I do find it strange to say it's like brushing your teeth without toothpaste though.
