    Default phosphoric acid

    Hi
    anyone know where I can buy phosphoric acid in 5 lt. volume
    in Brisbane or Gold coast, I tried the big green shed with no luck,
    I have used it for rust removal when building my steel yacht with great success in areas that sand blasting couldn't reach but that was a long time ago, I'm looking for straight undiluted acid not some brand name converter,
    Leroy.

    Try here

    Buy ORTHOPHOSPHORIC ACID 25% Online in Australia

    The 25% grade I think you can ship, but the 85% grade is classified as dangerous goods, and you'll have trouble purchasing it, unless you can find a local distributor.

    Also the 85% is only available in 2.5L

    I purchase mine from a cleaning chemical company in S.A, it's cheap, 85% phosphoric acid they just decant some of their raw stock into a container for me. a more expensive way to buy it is from a hydroponic shop as "ph down" just check it's 85% phosphoric acid
