PAA5 is 5% Peroxyacetic acid in hydrogen peroxide
- A powerful sanitiser effective against bacteria and their spores, yeasts, moulds, fungi, and their spores, and viruses
- PAA5’s sanitising action is rapid even at ambient temperatures
- PAA5 is of particular use for sanitising in breweries, cordial manufacturing plant and milk handling equipment as it is non-foaming, passivates stainless steel, may be used under a carbon dioxide head, and breaks down to acetic acid and oxygen

This is very corrosive and a strong oxidiser
Wear gloves, protective clothing and eye protection to avoid burns. Breathing the vapour from strong solutions may induce vomiting.
Metric Measurements
The strongest dilution recommendation is 1:100, and the weakest is 1:500. I decided on 1:150 for unknown reasons.

Re-Use
I have found that the diluted mix can be stored and re-used. If the mix is still quite clear after use I will store it for re-use. The moment it is not clear I will discard it. I discard the mix if it has been used six times or for three brew days.
Disclaimer
