If blowing-down of the column does not clean the probes sufficiently, use a stainless steel wire brush or fine emery cloth to clean the stainless steel rod portion of the probe. To clean the insulator, use a soft cloth and a mild detergent. If probes are removed at any time for replacement or inspection, the sealing gasket must be replaced. Probe

predominantly steel surface where dissolved oxygen can directly attack the metal. The high flow rates through this section preclude deposit buildup. Instead, deep hemispherical pits form in the tubes. These tubes are thinner than boiler tubes, and so can fail faster. In the boiler itself, excessive oxygen levels can lead to oxygen pitting and tube
