As far as antibiotics (presumably used appropriately to treat secondary infections) leading to more resistance: well, yeah - that’s pretty widely accepted.
I read somewhere, sometime, that the harsher disinfectants - the sort you can’t take internally, like bleach and Lysol - damage the microbes in such a way that resistance can’t really happen. As in, you’re destroying their cell membranes or viral coats or whatever. But I didn’t recall where, so I went googling for a cite.
This site (a cleaning products group, I gather) says that "For some ingredients it’s most unlikely that bacteria could develop tolerance because they literally take the bacteria apart, rather than interfering with their workings. ". It goes on to claim that there have been no reports of bacteria developing resistance to the use of cleaning products (something along the lines of “you can’t prove it” versus “proven NOT to happen”).
And a thread at Reddit which sums things up nicely:
Obviously that thread doesn’t have the citations but it’s much like what I recalled reading.
All in all, I would’t panic about the disinfectants - these procedures have been used for decades and there’ve been no reports of issues. And most people with covid-19 aren’t getting antibiotics. Just don’t go swilling any fish tank cleaner.
Besides, the biggest single factor in antibiotic over- and misuse, and resistance, is their use in livestock. If an animal is sick (and crowded feedlots are a great way to spread disease, but I digress) antibiotics are warranted, but I DO NOT advocate their use in poultry as a growth enhancer.
Yes, that’s why some poultry feeds have a nearly-homeopathic dose of tetracycline; it was discovered decades ago that a tiny dose of tetracycline makes some breeds of poultry grow faster, enough that they can go to market a day or two earlier.
