I've got a 10-radiator open-vented system.
I've drained it down and some of the water (15% perhaps) contained black sludge.
I have taken one of the radiators off and flushed it through outdoors with mains pressure water. I'm happy that this rad is now clear but the other 9 probably aren't, so i want to flush the whole system with a cleanser.
The question is, which one to use?
Btw, I've also put a brand new F&E tank in the loft - so that's one part of the system that doesn't need anything doing to it
Thanks in advance folks.

- Everbuild P11 System Cleanser
