When cleaning equipment designed for oxidizing gases, such as oxygen and nitrous oxide, the type of cleaner must be chosen carefully. Improper cleaning and testing with soap and water can leave residue, and cause corrosion, leading to a potentially dangerous situation. For maximum safety, any surface that comes into contact with an oxidizing gas (cylinder valves, regulators, pigtail connections, etc.) should be cleaned for oxygen service to an approved standard. SuperFlash oxygen equipment maintenance chemicals are designed specifically for this purpose, enabling you and your customers to use gas cylinders safely and economically.
