Methods for handling excessive carbon monoxide in vehicle exhaust emissions: 1. Clean the three-way catalytic converter: Use an IV drip method similar to human intravenous therapy to administer cleaning solution into the engine's vacuum tube. The solution enters the combustion chamber, burns off carbon deposits, enhances engine power, and then cleans the contaminated three-way catalytic converter in the exhaust pipe, restoring its original energy-saving and emission-reducing functions. 2. Replace aged or ineffective three-way catalytic converters: If the precious metals platinum, rhodium, and palladium inside have deteriorated and cleaning fails to restore their exhaust purification effect, spray a nano-precious metal solution (platinum, rhodium, palladium) into the removed catalytic converter. This can achieve performance similar to the original. 3. Fill the catalytic converter: Insert commercially available Fire Lotus three-way catalytic metal soft carriers (resembling steel wool) into the exhaust pipe to act as substitutes for the original catalytic converter's internal substrate. This method can also enhance exhaust purification effects for vehicles already equipped with catalytic converters.

How long after car painting can you wash the car?

After car painting, the time to wash the car can be divided into the following situations: 1. If the painting is done in a paint booth, you can wash the car as soon as the car is driven out, because the car has already stayed in the paint booth for 3 to 4 hours. 2. If the painting is done at a professional shop, you can wash the car after the staff hand over the car, because professional shops follow standard painting procedures, and washing the car after painting will not have any negative effects. 3. If the car is painted and picked up on the same day, it is recommended to wait 2 days before washing. Ensure sufficient ventilation and humidity, and you can wash the car after 6 to 7 hours. 4. In lower temperatures, it is advisable not to wash the car for a week, as the fresh paint is still fragile. Washing the car may cause the dirt and sand on the car's exterior to damage the clear coat on the paint surface during the scrubbing process.
