How often should a three-way catalytic converter cleaner be used?

[CaliFitz]

A three-way catalytic converter cleaner should be used every 20,000 to 30,000 kilometers or once a year. The three-way cleaner can simultaneously clean the engine's intake system, combustion system, and exhaust system, effectively, quickly, and efficiently removing carbon deposits in the intake tract and combustion chamber, as well as chemical complexes attached to the oxygen sensor and three-way catalytic converter. The removed carbon deposits and chemical complexes will be fully oxidized and burned into gases and expelled, achieving the goal of reducing exhaust emissions and significantly lowering CO and HC levels. The three-way catalytic converter contains three precious metals: platinum (Pt), rhodium (Rh), and palladium (Pd), hence the name 'three-way.' These three precious metals facilitate the reaction of the three main harmful gases produced after engine combustion, ultimately converting them into harmless carbon dioxide, nitrogen dioxide, and water.
