What Is Carburettor Cleaner, and How Do You Use It?
Carburettor-cleaning spray dissolves deposits, carbon build-up and other contaminants in vehicle carburettors. This improves engine performance and efficiency. The carburettor mixes petrol with air and delivers it to the combustion chamber, but accumulated dirt can reduce efficiency. Cleaning spray removes it to help the engine run more smoothly, improve performance and save fuel. It plays an important maintenance role and helps extend vehicle life.

What Is Carburettor-Cleaning Spray?
Carburettor cleaner is formulated to remove dirt and deposits from carburettors in internal combustion engines. The carburettor controls the petrol-to-air ratio for correct operation. Build-up reduces its efficiency and engine performance. The spray removes it effectively and restores function. Specialist ingredients make cleaning easier and help return the engine to optimum performance. Regular use can also extend engine life and reduce fuel consumption.
Properties of Carburettor Cleaner
Its effective formula is the main feature, providing easy use and deep cleaning. Selsil Carburettor Cleaner does not harm oxygen sensors or catalytic converters. It completely removes oil, dirt and varnish-like residue. Use it to clean residue from carburettor parts according to the packaging instructions.
How Do You Use It?
Carburettors lose performance as dirt and deposits build up, so regular cleaning is needed. Spray makes removal straightforward.
First stop the engine and let it cool. It must be cold before application.
Remove the air filter above the carburettor and spray into the intake. Usually spraying at a specified point on the carburettor is enough.
Finally, start the vehicle and run it at high revs for a few minutes to complete cleaning. Regular treatment improves performance and reduces fuel consumption.
Benefits of Carburettor Cleaner
Regular cleaning reduces fuel consumption for greater mileage. It also gives more stable engine operation and fewer faults. Using cleaner therefore extends vehicle life and improves efficiency.
It also reduces exhaust emissions. A clean carburettor releases fewer polluting gases and causes less environmental harm, benefiting both performance and the environment.
Frequently Asked Questions
- Is carburettor cleaner suitable for all vehicles?
Many products suit petrol vehicles, but diesel engines may need different products. Check label information about your engine type carefully to choose correctly.
- How often should it be used?
This depends on driving conditions. Use every 5,000–10,000 km is commonly recommended, but it is best to check the vehicle handbook and follow manufacturer instructions.
- Can it clean electronic fuel injection systems?
No. These sprays are designed only for carburetted engines. Electronic injection systems need specially made cleaners.
