Why Your Catalytic Converter Needs Cleaning

Over thousands of kilometres, carbon deposits accumulate inside your catalytic converter, reducing its ability to process exhaust gases efficiently. Signs you may need a cleaner include a noticeable drop in fuel economy, reduced engine responsiveness, or a sulphur-like odour from the exhaust. Regular use of a quality converter cleaner helps maintain optimal converter function and extends component life.

Frequently Asked Questions

Q: How does the RayHong Catalytic Converter Cleaner work?

A: The cleaner uses a ternary catalytic formula that, when added to your fuel tank, mixes with your fuel and passes through the combustion system. It breaks down and dissolves carbon deposits that have built up inside the catalytic converter, helping restore efficient exhaust processing and improve engine performance without any disassembly.

Q: Is this catalytic converter cleaner compatible with diesel vehicles?

A: Yes — the RayHong Catalytic Converter Cleaner is formulated to be compatible with both petrol and diesel engines. Always check your vehicle owner's manual or consult a mechanic if you are unsure about compatibility with your specific model.

Q: How often should I use a catalytic converter cleaner?

A: For general maintenance, using a catalytic converter cleaner every 5,000–10,000 km (or as part of each oil change interval) is a common recommendation. If you notice a drop in fuel economy or a sulphur smell from your exhaust, you may want to treat your vehicle sooner.

Q: Will this product clear my check-engine warning light?

A: If the warning light is triggered by carbon build-up affecting your catalytic converter's performance, cleaning the converter with this formula may help resolve the underlying cause. However, warning lights can have multiple causes — if the light persists after treatment, we recommend having your vehicle inspected by a qualified technician.
