I don't want to simply replace one hazardous chemical with another. The bleach is stubbornly clinging to my shower walls and I feel its effects every time I take a shower.
Ascorbic acid seems like the most natural solution to me, since it's a regular part of our diet. Online sources recommend ascorbic acid "but you should never use any other type of acid". I'd like to ask you chem experts: what's the difference? From what I've found, ascorbic acid plus bleach will create chlorine gas just like any other acid. It also forms sodium hydride, which appears to be a pretty nasty substance as well.
Are there any options? I looked into sodium theosulfate, which is recommended for fish tanks, but it seems it too is an irritant when inhaled. Why replace one irritant with another?
PS It is likely that NaOH is also present.
