Rated 5 out of 5 by from Self Contained and Easy This is the second time I've used this product - for good reasons! Aerosol simplicity - connect the cartridge to either the combi boiler filling loop or a convenient rad. bleed point, using the supplied connectors and pull the trigger. Ten to fifteen seconds later the job is complete. I removed the Magnaclean magnet for cleaning (did this a year ago) and very little residue - Good product Fernox

Rated 5 out of 5 by from Ease of use Make sure rad empty before commencing as the pressure from the aerosol is powerful, much easier to use than other container

Rated 4 out of 5 by from Easy to dose Central Heating System Supplied with three attachments, allowing fitment to either the air valve of a radiator, a radiator blank or the filling loop of a combi-boiler. Having chosen the latter to use, was very easy to attach, get a decent seal, and dose the system. No spill, no mess. Costly in comparison with other quantities, but the convenience outweighs the cost.
