How to Effectively Clean a Three-Way Catalytic Converter?

[ClaytonLynn]

Here are the methods for cleaning a three-way catalytic converter: 1. The drip cleaning method without disassembly utilizes the engine's own negative pressure to draw the catalytic converter cleaning fluid from the intake vacuum tube. After combustion in the combustion chamber, it creates a high-temperature oxidation environment on the surface of the catalytic converter. Through redox reactions, the chemical complexes clogging the catalytic converter are decomposed into sulfur dioxide and carbon dioxide gases, which are then expelled, restoring the catalytic converter's activity. 2. Complete disassembly and cleaning is a more thorough method. After removal, the catalytic converter cleaning fluid is directly poured into the catalytic converter for soaking, allowing the clogged particles to dissolve in the cleaning fluid, which is then drained from the catalytic converter.
