ELi5: Why can’t you boil a sponge to sanitize it?

Googling repeatedly tells you to just buy a new kitchen sponge, never boil them because it doesn’t work. But why wouldn’t it clean them?

Tried boiling, microwaving, washing in dishwasher, washing in laundry, soaking in bleach. None work. The cleaned sponge seems “fresh” for a day maybe then stinks again.

Only solutions I’ve even found is to replace it
