Shock chlorination raises both pH and the oxidation-reduction potential (ORP) of well water dramatically, thus increasing scaling within a well. Osorno’s well cleaning solution, however, lowers the pH to about 2, and lowers ORP into the reducing range. Under these conditions lime scale dissolves, and iron and manganese oxides are reduced to soluble and almost colourless compounds.
The well cleaning solution also disinfects the well, although not as strongly as Osorno’s Well Disinfectant (below). If both well cleaning and disinfection are required, well cleaning must always be the first step.
The chemicals used in this formulation are all food grade, so that any traces left in the well or in the pipe system pose no health risk.
