The body produces carbonic acid to deal with too much alkaline pH; just as it produces bicarbonate to deal with too much acid pH. The body has numerous redundant systems to adjust its narrow pH. There is no need for you to help. ...or hurt by ingesting too much acid. How much is too much? I don't know. I limit my soda drinks.
I use ozonated water to clean my grocery produce. Ozone will kill all nasty pathogens. It is a free radical. I use an ozonator for this; because as Arrowwind says, the ozonation does not last long.
