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?

Any chance you're the same "Lil Crow" who ran that portable sandwich shop in Grant Park, IL about a decade ago?

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.

A lot of shops use Cascade dish powder to clean oil out of the system. It contains Dawn's grease cutter. For rust use a product called Thermocure or Evaporust specifically made to remove cooling system rust. Ford also has a product for that purpose. I don't remember what it's called but can look it up if you need it.
