Sentinel X400 C/H Cleanser.
Bought (in conjunction with Sentinel X100) to clean a system that was old and sluggish and then add the Sentinel X100 to preserve any improvement in circulation,
The cleansing was dramatic, obviously, judging by the rapid heating up of radiators after just a couple of days and I intend running the cleanser for the remainder of the week and then draining down and filling up with the X100 rust inhibitor I bought at the same time.
If X400 will do this for an old 8mm micro bore system in a couple of days what will it do for larger bore piping ?

Reliable brand name
Sentinel X400 is recommended by Potterton and many other boiler manufacturers, easy to use and suitable for all types of boiler and pipe work.
