Narrative:
Aircraft performed an air turn-back due to a smell in the cabin. Myself and co-worker ran the aircraft for about 30 mins until the smell (which appeared to be from a compressor wash) was gone. We ran the bleed air system full hot the entire time and thought the fluid had been evaporated. The bleed air lines were not capped for the compressor wash. Better directions for that needed. I don't know when fluid was found in the system. We took off bleed lines and cleaned before running.
