Wow you caught it quick!
(This is in reference to using a cleaning agent to remove any residue from manufacturing processes that may be left on the pipe walls.)
I couldnt define what will be safe for your system as it depends what the component parts (ie seals, tubing...) are made from. I'm more of an electronics/software man than chemicals and research issues along that line as I come across them.
Using a very mild detergent (few drips of washing up liquid in the water) for about 24hrs total while testing hasnt had any negative effects for me in the 6 months my system has been running. I also didnt flush the system before refilling with ionised water, there is a real tiny amount of washing up liquid left in still (I can see little stacks of miniature white bubbles in any air pocket when the pump is stopped, they remain for a long time).
Longer term problems may still occur with rubber cracking maybe but for me I'm not too worried as it gives me an excuse to try something new. Also my radiator was used and you may end up with a larger concentration of detergent in your system if it hasnt anything to work on, should you have a new radiator.
I would recommend mild washing up liquid water if flushed out after and the seals wiped clean, or you can push your luck like me
