I'm wondering if it is possible to do a no rinse or minimal rinse CIP.
I know pbw is percarbonate and metasilicate and an unknown surfactant. If I were to make pbw at home I would omit the surfactant over concerns about head retention.
This leaves the percarbonate which becomes hydrogen peroxide and soda ash (sodium carbonate). The peroxide is non toxic and from what I've read the soda ash is safe in the concentrations that would be left in the residue.
Oh and the sodium metasilicate also appears to be non toxic-ish but there's less info out there on it.
I would be concerned about the effects of long term exposure. And even if it is safe it may still generate off flavors.
Looking through the old threads it appears that those who did not rinse pbw drank the resultant beer without issue but that is anecdotal and I'd prefer some hard facts from someone who understands chemistry better than I do.
Incidentally, what's in one step? It seems to be a decent no rinse cleaner.
