Brake fluid in power steering

I have put brake fluid in the power steering reservoir and drove it (YES I F*#KED UP). Drove for half and hour and then a groaning noise started whenever I accelerated and turned corners.
When I got home I tried to remove as much fluid as I could from the reservoir and turned the wheels side to side for more fluid to come out. Filled it up with Dexron 3 auto fluid, lifted the front wheels up and bled the fluid until no noise.
Went to use the car later and the noise was back and little bubbles were present in the reservoir as soon as I started it. Left the car overnight and topped it up in the morning and car worked fine, 10 minutes of driving and the noise was back. I have tried for the last half an hour to bleed the system again but no luck as the noise is still there and I am frustrated.
How can I be sure all the brake fluid is gone or have I done something to the power steering motor? I cannot see any visible leaks and there was no problems before the brake fluid.

what does the manual say to use? I would go with using that. The brake fluid is quite corrosive and you may have effed up your hydraulic system and you may need to replace it, or take it off of the car and go with manual steering.

atf IS normal "power steering fluid" for the vast majority of vehicles. (at least here) i dont know what you put in, but if power steer doesnt have a good oil, it will fuck out quickly! i feel sorry for both of you, but i'd put money on the pump being the stuffed part in both cases.

Continue to turn your wheel left and right until there are no bubbles at all. Chances are it is still containing lots of air.
