DUCTWORK CLEANING METHODS - HOW EFFECTIVE ARE THEY? The HVCA have issued TR/17, a guide to good practice, but does not recommend any one method in preference to another. However, a Swedish college conducted an evaluation of the same cleaning techniques and came up with some interesting findings. The Vasterbotton College of Health and Caring Sciences
conducted tests under controlled conditions to establish whichcleaning
techniques could be recommended for the College to procure, to clean its own
ventilation systems. After exhaustive tests, the results were as follows: The report concluded that the skipperball and air nozzle methods should not be used to clean the ventilation system and recommended a combination of hand brushing and powered brushing techniques. The report confirm the view that dirt needs to be brushed to dislodge it from duct surfaces and that "modern" air jetting techniques are of limited affect. Hygienic Maintenance Limited predominately use the tried and tested brushing techniques to ensure that a more thorough result is achieved. Alternative methods can be provided, if requested.
