Deep Clean Without Removing the Converter
Dust, grime, and carbon deposits can silently block your catalytic converter, reducing performance and triggering warning lights. This cleaner flushes out harmful buildup, keeping your exhaust system clear and your engine running strong.
Simply pour the cleaner into your fuel tank when 1/4 fuel remains. As you drive 30–50 km, the solution circulates through the system, breaking down carbon in your catalytic converter, fuel injectors, and sensors. Fill up afterward to complete the cleaning cycle.

Benefits
- Deep Carbon Deposit Removal: Breaks down stubborn carbon buildup in your catalytic converter, oxygen sensors, and fuel system components. This improves airflow and combustion, boosting engine responsiveness and fuel efficiency.
- Easy DIY Engine Cleaning: No tools or mechanical skills needed. Just pour into your fuel tank—no need to remove or disassemble parts. Safe for all gasoline, diesel, hybrid, and flex-fuel vehicles.
- Reduce Emissions, Pass Smog Tests: Improves your vehicle’s emission control system, reducing toxic exhaust fumes like CO, NOx, and HC. Helps prevent failed emissions tests and expensive repairs.
