A signal generator has a generator output. The signal generator is configured to generate first and second signals at the generator output. The first signal has a first frequency, and the second signal has a second frequency. Switching circuitry has a circuitry input and a circuitry output. The circuitry input is coupled to the generator output. The circuitry output is adapted to be coupled to an ultrasonic transducer mechanically coupled with a surface. The switching circuitry is configured to: provide the first signal to the ultrasonic transducer at the first frequency to reduce a fluid droplet on the surface from a first size to a second size; and provide the second signal to the ultrasonic transducer at the second frequency to reduce the fluid droplet from the second size to a third size.
