Just in the process of replacing some rads in our house, couldn't believe the amount of sludge that has come out the the old rads. No wonder our house never used to get very warm. I think the plumbers solution was to put bigger rads in by the looks of things.
Will the addition of Fernox MB-1 prevent this type of buildup? (after a flush of course).

Only after a complete power flush with active chems like DS40.
Imight be wrong but I'm suspicious that MB-1 coats any iron oxides left behind and makes a nasty sort of slimy stuff. Anyone else come across this?
