Phosphoric acid (AKA orthophosphoric acid or H3PO4) is a mineral inorganic acid that can be used as a non-foaming/non-rinse sanitiser when diluted to water to a concentration of 1mL/2L.


    Our Phosphoric acid is also an excellent chemical to use when passivying stainless steel. 

    This formula is also great at adjusting the pH of Sparge water and your Mash pH. If you prefer to use the traditional pH adjusting ingredients we would suggest Acidulated Malt or our Lactic Acid 88%.


    Phosphoric acid can also be completely motabilised by yeast and will also act as a yeast nutrient if it ends up in your fermenter.


    If this does come into contact with your skin undiluted, please rinse under cold water for 5-15 minutes. It can stain coloured clothes undiluted!
