Can you pressure wash with an air compressor?
No, an air compressor cannot become a pressure washer. Some air compressor accessory makers sell tools like a "Syphon Water Jet Cleaning Gun" but ultimately it's never going to be a pressure water because an air compressor delivers air at up to about 200 psi where a pressure washer delivers water at about 1600 psi. The two applications are similar in theory but much different in practice.
