I use a small RO plant to make 20l of distilled water and re-use that until it goes cloudy. It might last me 6 months before I need to chuck it. Thirstyboy mentioned once thaty cloudy doesn't necessarily mean its no good. Starsan works on pH so would be worth checking the pH before chucking it.brewologist said:A little off topic but is everyone using tap water to mix with their starsan?
I've read somewhere before that it doesn't last that long (ph might drop or something) using tap water and
distilled water will provide a longer shelf life once its mixed up.
True or False.
I usually mix up 10L for brew day then chuck it.
And no, never had an infection since I started using Starsan this way.
