Is Cleaning the Three-Way Catalytic Converter Useful?

[LawsonDella]

Cleaning the three-way catalytic converter is useful and necessary. Since fuel contains harmful substances such as sulfur and phosphorus, combustion can form chemical complexes on the surface of the oxygen sensor and inside the three-way catalytic converter. Over time, carbon deposits will accumulate. If not cleaned in time, it can lead to failures such as poisoning and malfunction of the oxygen sensor and three-way catalytic converter, ultimately causing abnormal engine operation, increased fuel consumption, reduced power, and excessive exhaust emissions. The function of a three-way catalytic cleaner is to remove chemical substances like sulfur and phosphorus from the surface of the catalytic converter, unclog exhaust pipe blockages, and restore the activity of the three-way catalytic converter. However, if the blockage is severe, relying solely on cleaner may not be very effective. In such cases, disassembly and cleaning may be necessary, and if the converter is damaged or severely blocked, it should be replaced directly.
