Dishwasher guide: salt will harm the stainless steel lining. What about salt water in stainless steel pots? (mander.xyz)

The manual for my dishwasher says to refill salt just before running a wash cycle, because if any grains of salt spill onto the stainless steel interior it will corrode. If it runs right away, no issue because the salt is quickly dissolved, diluted, and flushed.

So then I realized when I cook pasta I heavily salt the water (following the advice that pasta water should taste as salty as the ocean). But what happens when I leave that highly salty brine in a pot, sometimes for a couple days to reuse it? Does that risk corroding the pots?

i think e. coli grow in the lab in like 4-8 hours. Thats obviously in specially designed nutrient soup, and they prolly start from more than couple of spores in the air shrug-outta-hecks

Feely wise, in summer if i forget to put soup in fridge it goes bad in like 2 days, so more time than 1 day (and it gets friendly lacto something bacteria, so just gets acidic, not toxic). Fungi starts to grow in like a week.

I think it (whatcha doing) is safe-ish from toxins point (cause 1 day when they grow exponentially in 3-7 days is much less of problem), but still seems sketchy. Toxins are mainly fungi, with bacteria you likely get friendly ones which makes vinegar
