污泥取樣工具長期使用后會(huì)出現(xiàn)內(nèi)部殘留物使壁管朦朧清晰度降低。清潔刷配以溫和的清潔劑，適當(dāng)溫度的水，可是有效的清除這些污漬，從而使采集的樣品可以清晰準(zhǔn)確的讀數(shù)。組成由鍍鋅鋼絲和聚酯刷毛。刷子可能沒辦法清楚一些油酯，那么我們可以使用清潔棒和棉質(zhì)清潔帶來清除這些油漬。

After prolonged use, residue and filmy deposits may build up inside the Sludge Judge®. The cleaning brush used with a mild detergent and warm water will help break up these materials and keep the unit clear so accurate sludge readings can be taken. It is made of galvanized steel wire and polyester bristles. The brush may not be able to clean oil and grease – see the cleaning rod for this application. Disassemble the unit and clean each section separately. Use for Sludge Judge® and Sludge Judge® Ultra. 6 ft. 1" （1.83 m 2.54 cm） diameter bristle.
