If your model includes a temperature control, set it to around 130°F (50°C) for optimal performance.
The right temperature improves the cleaning efficiency without damaging metal components. Before starting, read the manual for your specific cleaner, as ultrasonic cleaner settings for carburetors can vary between models. Proper setup ensures safe, effective, and consistent results every time.
Adding the Cleaning Solution
Fill the ultrasonic cleaner tank halfway with clean water. Add a water-based cleaning solution—either a carburetor cleaning fluid or a mild degreaser like Simple Green—at a 1–5% concentration. For example, a 2-liter tank needs 20–100 milliliters of cleaning fluid. Stir gently to mix, avoiding splashes.
Using the correct cleaning solution improves dirt removal and enhances the cleaning of the carburetor with the ultrasonic cleaner process. Avoid harsh or flammable chemicals, as they can damage both the machine and the parts. The right mix allows the ultrasonic waves to loosen stubborn grime effectively, leading to cleaner results after the first cycle.
Placing the Parts in the Cleaner
Place the carburetor metal parts of the engine in a basket in an even manner, such that the parts do not come into contact. Such spacing enables the ultrasonic waves to cover all the surfaces. Dip the basket in the tank until the pieces are completely covered by the solution.
With small pieces, wrap them in a plastic bag containing cleaning solution, then add them to the tank to keep them safe. Remember to put only metal stuff inside; no rubber, plastic, or electronic parts will be intact. Correct part placement is also important in obtaining optimum results when using an ultrasonic cleaner to clean carburetors, as it gives an equal clean to all areas of the part.
Running the Cleaning Cycle
Close the lid of the ultrasonic cleaner and set the timer for 15–30 minutes.
