Debris rattling inside radiator

[Guzzles]

Hi can you help?

I have recently successfully de-scaled my boiler with DS-40 (added to H/W side only for 24hrs, then neutralised). As part of that process I drained the whole system and added inhibitor (Sentnel X-100 plus X-200). Unfortunately I now have some form of debris rattling in a towel radiator, probably shifted during the draining/filling process. I was going to do the following, but would be grateful for any comments based on previous experiences.

1. Wait a week to see if it shifts (its only been there for a couple of days)
2. Lock off all radiators apart from this one and try to flush it through
3. Turn the pump around and see if it will go back to where it come from.

A rattling noise could be caused by air in the system which often finds its way into the towel rail. If you think it's solid debris, you don't want to risk sending it round the system to do damage elsewhere, so isolate the towel rad, undo the unions and drain and flush the towel rail.
