Clean away fouling on the sensor as follows depending on the type of fouling:
1. Oily and greasy films:
Clean with grease remover, e.g. alcohol, as well as hot water and (alkaline) agents
containing surfactants (e.g. dishwashing detergent).
2. Lime, cyanide and metal hydroxide buildup and low solubility organic buildup:
Dissolve buildup with diluted hydrochloric acid (3 %) and then rinse thoroughly with
plenty of clear water.
3. Sulfidic buildup (from flue gas desulfurization or sewage treatment plants):
Use a mixture of hydrochloric acid (3 %) and thiocarbamide (commercially available)
and then rinse thoroughly with plenty of clear water.
4. Buildup containing proteins (e.g. food industry):
Use a mixture of hydrochloric acid (0.5 %) and pepsin (commercially available) and then
rinse thoroughly with plenty of clear water.
