10. A method comprising:
deploying a downhole tool coupled to a tubing string downhole in a wellbore;
coupling an acoustic actuator to the tubing string proximate the downhole tool; and
generating, by the acoustic actuator, an acoustic signal to:
vibrate the tubing string proximate the downhole tool via the acoustic signal;
generate a fluidic disturbance in downhole fluid within the tubing string for preventing formation of contaminants on the downhole tool in response to vibrating the tubing string, wherein the fluidic disturbance comprises an acoustic microstreaming of the downhole fluid; and
transport, by micro-oscillations in the downhole fluid generated by the acoustic microstreaming, the contaminants away from the downhole tool.
