Yes, there are a few non-removal cleaning methods that are commonly used in Pakistan with mixed success:

Effective methods:
Fuel Additives:
Use catalytic converter o r fuel system cleaners like Liqui Moly, STP mixed with fuel. Run for 100–200 km.

Highway Drive Cleaning:
Drive at higher RPMs 3000–4000 on a highway for 20–30 minutes. This helps burn off mild blockages.

Spray Cleaning Mechanics Job:
Some workshops spray a decarbonizing solution through the O2 sensor port, then run the engine at high RPM.

Important:
These methods work only for mild to moderate clogs. Severely blocked converters usually need removal and manual cleaning o r replacement.
