Sentinel Rapid Dose X400 Sludge Remover 400ml 4.5 5 2 2
Usual Sentinel product. I have used Sentinel before and found it works, so I am not reviewing the product but the applicator. What they don't tell you is it will not work with the bleed valves that have a hole at the side to direct the water away like the ones you get on ladder rads! I followed the instructions to the letter and as soon as I turned the valves back on and expected the little rubber bullet to seal the end a 4 foot jet of water shot all over me and the bathroom! After mopping up (and repairing the rad valve that had decided to leak as well after operating it) I tried a normal type rad. I must say it worked well with little spillage, but be warned!! 27 Dec 2013
Sludge remover I can't really get excited about sludge remover - what can I say - I squirted it into the radiator as per instructions - I presume it did its job - no way of telling really but at least it showed the wife that I was willing to do DIY jobs around the house. 31 Oct 2011
