Cleaning and Rinsing ­ General Considerations
(11) Cleaning and rinsing of the components should be done using clean, fresh water. If available, distilled
water is recommended to maintain oxygen cleanliness.
(12) Only use degreasers that leave no organic residue (clear Simple Green, dye­free Dawn dishwashing
liquid, or Blue Gold Cleaner as examples).
(13) To deal with corrosion, use a 50/50 vinegar­water solution and nylon brushes.
(14) Allow parts to air dry without the use of cloths that may leave fibers. For regulators that are going to be
used with Oxygen percentages above 40%, a UV light is strongly recommended to check for organic
contamination.
(15) Once all service procedures have been completed and bench testing done, in water testing in a confined
environment such as a swimming pool is recommended to confirm proper function before taking the
regulator on an actual dive.
Cleaning of Regulator Parts
(16)
Cleaning­
Cleaning of the parts that are going to be re­used is one of the most critical steps in servicing
the regulator. As was stated earlier, use the proper solutions for the job at hand. Vinegar and water are not
as useful for removing lubricating grease as one of the detergents that were noted. By the same token,
those detergents are not as efficient as the vinegar/water mix in dealing with corrosive buildup.
(17) Therefore, where you have a buildup of corrosion, you may also have lubricant on the surface of the
part. Before dealing with the corrosion, use hot soapy water and a soft brush to remove the lubricant. Then
use the acidic solution to deal with the corrosion.
(18) Once the corrosion has been dealt with, wash the parts using a fresh soap and water solution while
wearing nitrile gloves to reduce the risk of contaminating the parts with skin oils. Rinse the parts with clean
running water, distilled is preferred, that is allowed to drain freely. A plastic pasta colander available at any
store is excellent for this. For very small parts, a mesh strainer for sink drains works well. Often sold as a
set, they are inexpensive and can be used for many types of regulator components. See the photographs of
each in the tool section.
(19) After washing and rinsing the regulator parts, allow them to air dry. Using a drying rack will aid in this,
as well as having the air in the room circulating. Do not lay the parts on a paper or cloth towel. Doing so runs
the risk of having fibers stick to them that will cause issues with sealing. In addition to this, fibers can be a
hazard when using the regulator with high oxygen content mixes.
(20) Once the parts have dried completely, lay them out in order of assembly on the pad used on the work
surface. Making sure that it has been cleaned and is free of contaminants. A rubber or silicone mat of suitable
size works well for this. You can also use small clean containers to keep the parts organized. Once the parts
have been cleaned and dried, they need to be inspected before starting the assembly process. This is to
ensure that no damage or defects exist that were hidden by corrosion, residual lubrication, or other
contaminants that have now been removed.
