Why Your Catalytic Converter Needs Cleaning

Over time, carbon deposits and fuel residue build up inside your catalytic converter and fuel system, causing reduced power, poor fuel economy, rough idling, and increased emissions. Regular cleaning with a quality fuel additive can help keep your system running cleanly and efficiently.

Frequently Asked Questions

Q: How does the RayHong Catalytic Converter Cleaner work?

A: The RayHong cleaner uses a specially formulated ternary catalytic cleaning agent that mixes with your fuel. As the engine runs, it circulates through the fuel injectors, combustion chamber, oxygen sensors, and catalytic converter, dissolving carbon deposits and restoring optimal flow and chemical conversion efficiency — all without removing any parts.

Q: Will this catalytic converter cleaner work on my diesel vehicle?

A: Yes! The RayHong formula is designed to work with both gasoline and diesel engines, making it a versatile solution for a wide range of cars, trucks, and SUVs.

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

A: For preventive maintenance, we recommend using one bottle every 5,000–10,000 km or at every other oil change. If you are experiencing active symptoms such as a check-engine light, reduced power, or a rotten-egg smell, use it right away and re-evaluate after a full tank cycle.

Q: Is this product safe for my engine and fuel system?

A: Yes. The RayHong Catalytic Converter Cleaner contains no high-concern chemicals and is formulated to be safe for use in modern fuel systems, including those with oxygen sensors, fuel injectors, and catalytic converters. Always follow the usage instructions for best results.

Q: Can this cleaner turn off my check-engine light?

A: If your check-engine light is triggered by emission-related fault codes due to a dirty or under-performing catalytic converter, cleaning the converter may help resolve the underlying issue and clear the code after a few drive cycles. For fault codes related to mechanical failures, please consult a qualified mechanic.
