How to Clean a Car's Three-Way Catalytic Converter?

[JohnRose]

Method for cleaning a car's three-way catalytic converter: Place the removed three-way catalytic converter upright in a container. Shake a bottle of three-way catalytic converter cleaner well and pour it into the high-pressure spray gun's container, then tighten it. Connect the air hose and evenly spray the cleaner onto the inner grid of the three-way catalytic converter. You can repeatedly turn the converter around for thorough cleaning. The cleaning solution will penetrate evenly into the deep layers of carbon deposits, quickly forming bubbles to dissolve the carbon deposits, which will then turn into sludge and flow out. The three-way catalytic converter is an important external purification device installed in a car's exhaust system. It converts harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides emitted from the car's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions.
