Rated 4 out of 5 by Shame about label Used this to clean my 10 year old system before flushing (not rinsing). Appears to have loosened it all up judging by the black muck I got out. Stuck the provided sticky label onto the boiler - which I could not get off the packet in one piece and then could not find a pen that would write on it! 16 Jan 2016

Rated 5 out of 5 by Yearly maintenance. I use this in conjunction with the No Nonsense inhibitor, as a yearly maintenance exercise. Keeps the system clear, and at a good price too. 15 Sep 2015
Rated 5 out of 5 by Great Value I used this product for the first time, I usually use Fernox or Sentinal product. The thing which impressed me was that the cleaner was a dark brown when I pored it in to the system, so when you were flushing the system you could see when it was fully flushed and running clear, it also cleared out a great deal of sludge from the system, very impressed with the product. 12 Sep 2015

Just to further clarify the above question. The inhibitor was added a few years ago. Because the central heating is making noise I want to remove sludge etc. from the system by using this cleaner. Is it essential to drain the system until the water runs clean to get rid of the old inhibitor before adding this cleaner or can I add it without draining first? I do understand that the system will have to be drained after a maximum of seven days of adding the cleaner before adding the inhibitor.

Answer: 
It's only necessary to drain the system after you have added the cleaner even if inhibitor is present. If you have the time and inclination to drain the system before you add the cleaner it's quite likely that you will get better overall results.

Answer: 
Yes it's safe to add on top of inhibitor. No need to drain down first. After cleaning and flushing it will be necessary to add fresh inhibitor.

Would it do any harm to add this at the same time as the inhibitor and just leave it in!?

Answer: 
Sorry that's not a good idea. In the UK the best practice is BS7593 which separates the cleaning and inhibition cycles. Use the cleaner for the prescribed time, flush until water runs clear, then refill and add the inhibitor.
