Ear Cleaning on Raven AGAIN!

Hello,  this morning my male raven was scratching his ear, which is bizarre since i just cleaned them Saturday last.  I am a bit concerned so i'll post the picture of the swab and what i used to clean his ear.  I just dip the Q-tip (barely) into this wash and use it on his ears.  My dog Kara has constant ear infections so i know how to clean ears since i do hers on a weekly basis so anyway here's the pictures.

My vet told me to use some kitten ear wash stuff. A drop and squish around with finger then let them shake it out. Then to use qtip to wipe out. What's in that stuff? Just saline?
