Cleaning carburettor with ultrasound: Effective methods and tips
A clean carburetor is crucial for the performance of motorcycles, classic cars, and many other machines. However, cleaning it is often laborious: winding passages, stubborn deposits, and delicate components make conventional methods time-consuming and error-prone. With an ultrasonic cleaner , however, carburetor cleaning is thorough, gentle, and significantly faster.
Why clean carburetors in an ultrasonic bath?
A carburetor transports and atomizes the fuel – this is achieved through the use of tiny jets and passages. Over time, however, oil, dirt, gasoline residue, and oxidation build up. This can lead to loss of power, starting difficulties, or even engine damage.
Ultrasonic cleaning offers clear advantages:
-
Thorough deep cleaning even in the smallest channels and holes
-
No aggressive chemicals required – ideal for the environment and materials
-
Time-saving – while cleaning, there is time for other work
-
Extended service life of the carburettors through regular maintenance
How ultrasonic cleaning works
The process is based on the cavitation principle : high-frequency sound waves create millions of tiny bubbles in the cleaning fluid. As they collapse, they dislodge dirt particles, even from inaccessible areas. This gently yet highly effective way of cleaning surfaces.
For carburettors, we recommend the cleaning concentrate EM-404 , as it is especially suitable for aluminum and die-casting.
