Hi all

Anyone have experience of both product ranges?

Despite using fernox cleaner a year or so back - left running for a week in
the system IIRC, I recently had to clear a blockage of powdery magnetite
from a central heating 15mm plastic radiator feed.

Does anyone have good experience of FerroQuest by Sentinel (or any other
similar product) which is likely to dissolve and remove this sort of
residue? The blockage removed was more like finely ground coal than a
powdery sludge usually flushed through rads!
8 rads have been removed and been thoroughly blasted through or replaced, 6
have not been disturbed.
