A catalytic converter cleaner is a specialized automotive maintenance product designed to remove carbon deposits, oil residues, and other contaminants from your vehicle’s catalytic converter. It works by breaking down stubborn buildups, restoring exhaust gas flow, and helping the converter regain its efficiency in reducing harmful emissions.

Consider using our cleaner if you notice:

• Check Engine Light (CEL) triggered by catalytic converter-related faults 

• Reduced engine performance, sluggish acceleration, or decreased fuel economy

• Strong sulfur or rotten egg smell from the exhaust

For preventive maintenance, we recommend using it every 3,000–5,000 miles or during routine oil changes.

Important Note: This product is intended for routine maintenance and care. It is designed to clean and help prevent carbon buildup and clogging in components like the catalytic converter. It cannot repair any physical, structural, or existing mechanical damage. If your vehicle already has severe issues, consulting a professional mechanic is recommended.

Yes! Our catalytic converter cleaner is formulated to be safe for all gasoline-powered cars, trucks, SUVs, and hybrid vehicles equipped with standard catalytic converters. It is not recommended for diesel engines or vehicles with damaged/melted converters. It will not harm oxygen sensors, fuel injectors, or other engine components.

Using our product is quick and easy—no professional tools required:
 
1. Ensure your vehicle’s fuel tank is sufficiently full (at least 3/4 full is ideal).
2. Shake the cleaner bottle vigorously for 1–2 minutes.
3. Pour the entire contents into the fuel tank.
4. Drive your vehicle normally for at least 30–50 miles to allow the cleaner to circulate and thoroughly clean the converter.

No. If your catalytic converter has suffered physical damage (e.g., melted, cracked, or irreparably clogged), our cleaner cannot reverse the damage. It is designed to clean and restore partially clogged or underperforming converters, prevent future buildup, and help marginally failing units pass emissions tests. Severely damaged converters require replacement.

Many users notice improved acceleration and reduced exhaust odor within 1–2 days of use. For Check Engine Light issues related to converter efficiency, the light may turn off automatically after driving 50–100 miles post-treatment. For emissions test preparation, we recommend using the cleaner at least 3–5 days before the test.

Yes, our catalytic converter cleaner is compatible with most fuel system cleaners, fuel stabilizers, and octane boosters. For optimal results, we suggest adding our cleaner first, then using other additives after driving a few miles.
