This synthetic lube is a perfluoropolyether, one of the most inert materials known. The brand is Christolube MCG 111, NOT to be confused with Dow 111 silicone grease which is NOT O2 compatible. Unlike other synthetic O2 lubes, this one does NOT get viscous at low temperatures and works well in regulators used in cold waters. Use this grease in regulators or diving gear exposed to gas mixtures containing O2 levels of 23% or more. For Nitrox and O2 applications, Oxy-compatible lubricants must be...

Prior to Nitrox/O2 usage, visibly dirty or rusty dive tanks require abrasive tumbling prior to any degreasing treatment. Tumbling with ceramic media and citric acid (citrate) cleaner usually gives excellent results. Citrates are widely used in the metal finishing and electronics industries for oxy-cleaning processes; they are completely non-toxic, unregulated substances. Global cleaner is diluted 1 oz. per gallon of water for actual use.
