Oxygen cylinder is a device for storing and transporting oxygen, which is usually used in medical and industrial fields. Because oxygen is flammable and oxidizing, it is not recommended to use ordinary cleaners such as washing powder for cleaning. The chemical components in the washing powder will trigger a reaction, aggravate the dirt on the surface of oxygen bottles and even lead to safety problems. If the outer surface of the oxygen cylinder is dirty, it should be wiped with a soft and clean cloth or paper towel first, and a small amount of warm water or neutral detergent can be added for cleaning. When cleaning, make sure to use anti-static tools to avoid sparks and ensure safety.
