I have flushed cooling system 2 times and still have rust. Can I use any kind of washing powder?

Used dawn detergent to flush mine out when the system got fuel in it.

no idea on rust, though, other than just flushing it multiple times to try to clean it up.

had straight water been run in this for any amount of time?

You can use some detergent in it. The biggest thing is to get it filled back up with a top quality antifreeze ASAP. You may actually have to do this more than once if you have neglected the system and ran straight water or crappy super watered down antifreeze.
