Cleansol Phosphoric Acid 85%
About this item
Cleansol Phosphoric Acid 85% is orthophosphoric acid (H₃PO₄) – a clear, syrupy, non-volatile mineral acid. It dissolves limescale and rust and, on steel, leaves a thin protective iron phosphate layer, which makes it the standard acid for descalers, rust removers and metal pre-treatment. It is also used in toilet and tile cleaners, for pH adjustment and in fertiliser and chemical manufacturing. Cleansol repacks it from bulk into convenient 500 ml, 1 Ltr and 5 Ltr packs, with a GST invoice. Bulk packs of 10, 25 and 50 kg are available on enquiry.
