Excellent video, thank you very much for sharing it my dear. Many people ask us if it is necessary to use dezmineralized water. This is super important since many parts of the engine are made of Titanium. If the technician uses normal water, it contains chlorine. Chlorine is highly harmful to titanium, which generates micro-fibers that could deteriorate quickly or even generate a detachment of a component that is made of titanium (blades, compressor stages, etc.).
