Of course no one is dumb enough to inject disinfectant into their veins.
You asked if I heard it or read the transcript. Well yeah, here it is:
What does "something like that by injection inside, or almost a cleaning" mean? Because I'm pretty sure medical science has been around for quite a while to discern whether full body cleaning is a viable treatment against a viral infection or not.
And I will give you he doesn't mean "literally inject surface cleaner into patients", but then, what is he trying to say? To do something with a similar substance inside the body? Again, does he think virology was invented yesterday? Unless he's too much of a boomer to know what he's saying, it sounds like he's proposing the use of some kind of liquid to physically remove the virus from inside the patient's body, as if it was something that you can just clean with a mop. Then there is the chemical impossibilty of creating a substance that destroys the membranes of viruses and doesn't damage human cells, because both their membranes are made of the same thing. You can't just come up with magic potions that clean your body of Communist Chinese Viruses. And to top it all of, what would be the way to administrate this cleaning medication? Flooding the lungs with it? Water is enough to cause grave problems doing that, imagine Trump Disinfectant then.
He sounds like an extremely ignorant person or a small child trying to think out the solution to a problem: "why not just make disinfectant that kills the virus but doesn't kill you duh?" "why not just make more money so no one is poor duh?" "why not burn all the plastic so it doesn't pollute the sea duh?"
