6.2 Pitot Tube Cleaning Procedure
If the Pitot tube is clogged, it may need to be flushed or blown out. The cleaner used depends on the
process and what has accumulated in the sample line. Many lines can be cleaned by flushing with
water, Simple Green, or vinegar. In other cases, Acetone may needed. The best way to determine what
will work is to start with water, move to Simple Green or Vinegar and finally Acetone.
6.3 Sample Line Cleaning Procedure
