Attach a hose to the inlet then the hose to an outside tap and just leave it running for abit. Did this when my Mayhems solid white broke apart in my system and i ended up with a crap ton of white particles in stuck in the rads. A good few mins on full will help loose all the particles inside and eject it out.

difficult if you can't remove the rads. as above the best way is to use an enormous amount of water and the easiest way to do that is with a hose and the mains. I can't really advise unless the rads can be removed. I usually flush mine in a bath with a submersible pond pump connected to them. It's all about volume.

50/50 water and vinegar may do the trick

Same issue with the pastel white. Never again.

I switched to EK Cryo solid colours and so far been great, no breaking apart and no weird changes in colour thankfully.

To be fair, I was gutted. Looked great for the first hour

Despite Mayhems shipping the whole cleaning kit, and new clear coolant, taking apart a bay reservoir and a monoblock wasn't a pleasant task, plus all the tubbing needed replacing.

Heard about the EK. Was tempted, specially the Mystic Fog, but maybe in the future.

Probably because it's adding a whole load of new chemicals to the loop and we don't know how the contents of the loop will react. We also don't know what state the loop is in after soap (pH levels, surface chemicals, residual soap etc).

Also if it's stubbornly stuck in the rads it's probably not a matter of needing soap, but agitation to really rinse off any deposits and gunk in corners.

TBF there is a loop cleaning kit which effectively has a "soap" product designed for WC loops, from Mayhems.
