Rated 2 out of 5 by from It didn't. Going by our Magnaclean filter there wasn't any sign of the system being de-sludged, there wasn't any evidence of particles sticking to the magnet after two weeks. The water was dirty brown but it looked as if the pipes/sludge were being given a clean but not a clear out. Perhaps a power flush is the next job.

Rated 5 out of 5 by from Brilliant! I can't recommend this enough, short of having to power flush our system I decided to give this a go. Left in system for 3 weeks running and all cold spots have gone in different radiators. Fantastic stuff!
