Ultra Sonic Carburetor Cleaning - Ultra Sonic cleaning is the most effective way to have your carbs cleaned. The carb bodies are immersed in a non-corrosive heated solution and treated with 40KHz sound pressure waves that clean 100% of all inner and outer surfaces and carb passages. This cleaning far exceeds normal carb cleaning with carb cleaner and wires which simply can't remove all the debris and residue as effectively an Ultra Sonic washer can becuase it cleans 100% of all surfaces. An ultrasonic cleaner works by the energy released from the collapse of millions of microscopic cavitations near the dirty surface.
