CHAPTER 4 CLEANING SOLUTIONS
4.1 Soapy Water
A solution of domestic soapy clean warm water will remove dirt and stains from the
mask and harness.
4.2 Disinfectants
TriGene II (concentrate supplied in multiples of 5 litres, Part No. SM039) is the only
disinfectant recommended by Divex for use with the Ultralite II BIBS mask.
4.3 Ultrasonic Cleaning
If, for any reason, hydrocarbon grease or metal filings have contaminated the mask,
the complete assembly and hoses should be striped down and cleaned in an
ultrasonic bath using an approved oxygen cleaning procedure.
4.4 Material Compatibility
Extensive tests by Divex have resulted in the recommendation in section 4.2
(page 9). It is wholly the responsibility of the user to verify compatibility with the
materials used within the construction of the mask. These materials are noted in
“Service Manual for the Ultralite 2 Overboard Dump Diving Chamber Breathing
Mask” – document number OM079 Chapter 10.
