Pink non-toxic antifreeze and system sanitization

You still have to flush that pink c*** out of the system in the spring, this requires multiple flushes, Might as well add 1/4 cup per 15 gallons of bleach to the first flush and 1/2 cup to 1 cup of baking soda to the 2nd flush.

Which by the way is why I used air after the first winter.. No need to flush that out,, But I still sanitized in the spring.
