What to use to clean carburetor?


Cleaning a carburetor is an essential maintenance task for anyone who owns a vehicle with a carbureted engine. Over time, carburetors can become clogged with dirt, debris, and varnish, leading to poor engine performance and fuel efficiency. To restore optimal functionality, it is crucial to clean the carburetor regularly. But what should you use to clean a carburetor effectively? In this article, we will explore the various options available and provide insights into the best materials and methods for cleaning a carburetor.

Using Carburetor Cleaner

Materials used: Carburetor cleaner, safety goggles, gloves, cleaning brush, compressed air.

Carburetor cleaner is specifically designed to dissolve and remove the deposits that accumulate in carburetors. It comes in aerosol cans and is readily available at auto parts stores. When using carburetor cleaner, it is essential to follow the instructions on the can and take necessary safety precautions.

To clean a carburetor with carburetor cleaner, start by removing the air cleaner and disconnecting any fuel lines attached to the carburetor. Spray the cleaner directly into the carburetor, focusing on the various components such as the throttle plate, jets, and float bowl. Use a cleaning brush to scrub away any stubborn deposits. Finally, use compressed air to blow out any remaining cleaner and debris.

Ultrasonic Cleaning

Materials used: Ultrasonic cleaner, carburetor cleaning solution.

Ultrasonic cleaning is a highly effective method for cleaning carburetors. It involves using an ultrasonic cleaner, which generates high-frequency sound waves to create tiny bubbles in a cleaning solution. These bubbles implode, creating a scrubbing action that can reach even the most intricate parts of a carburetor.

To clean a carburetor using an ultrasonic cleaner, disassemble the carburetor and place the individual components in the cleaner filled with a carburetor cleaning solution. Turn on the ultrasonic cleaner and let it run for the recommended duration. Once the cleaning cycle is complete, rinse the components thoroughly with water and allow them to dry before reassembly.

Manual Cleaning

Materials used: Safety goggles, gloves, carburetor cleaning solution, cleaning brush, toothbrush, compressed air.

Manual cleaning is a more time-consuming method but can be effective for heavily soiled carburetors. Start by disassembling the carburetor and soaking the components in a carburetor cleaning solution. Use a cleaning brush or toothbrush to scrub away the deposits, paying close attention to small orifices and passages. Rinse the components with water and use compressed air to blow out any remaining debris before reassembly.


Cleaning a carburetor is crucial for maintaining optimal engine performance and fuel efficiency. Whether you choose to use carburetor cleaner, ultrasonic cleaning, or manual cleaning, it is essential to follow the recommended procedures and safety precautions. Regular carburetor cleaning will help prolong the life of your engine and ensure smooth operation.
