Frequently Asked Questions
Can this cleaner help fix a clogged catalytic converter?
Yes, our Catalytic Converter Cleaner can help dissolve minor clogs and buildup in the converter, improving performance and reducing odors. However, for severe blockages or internal damage, professional servicing or replacement may still be necessary.
How often should I use this cleaner?
For optimal results, use the cleaner every 3,000 to 5,000 miles or during routine oil changes. If you drive frequently in stop-and-go traffic or notice poor fuel efficiency, you may benefit from more frequent applications to maintain your exhaust system’s cleanliness.
How do I apply the cleaner?
Simply pour the full bottle into a nearly empty fuel tank, then add 10–15 gallons of gasoline. Drive normally so the solution can circulate through the system, cleaning the catalytic converter, oxygen sensors, and fuel injectors without requiring removal or special tools.
