Fernox F3 Central Heating Cleaner 500ml is rated 4.4 out of 5 by 23.
Rated 5 out of 5 by from central heating cleaner clear instructions - cheap

Rated 3 out of 5 by from Coke Cola water The colour of Fernox F3 is a brown rusty colour so even if your system has clean water in it, it will show as coke cola upon draining to show its removed all the filth when it might not have done anything. Fernox F3 should be colourless otherwise how can you tell if its the actual sludge etc it has removed upon draining or the colour of Fernox F3 itself coming out. Having said this and to be fair, it did improved the hot/cold temp fluctuation in our showerbath and i had put 2x 500ml bottles of The F3 in and ran it in the system for 5 days before draining. It took about 2 hours of constant draining with inlets fully open at combi boiler to clear the water of the dye in the Fernox F3. That done, i put 2 x 500ml of Fernox F1 inhibitor and after a few days of running system, i drained a little water from the system to add 1x 500ml Fernox sealer for good measure.

Rated 5 out of 5 by from Silent radiators Bought this a couple of years ago to clean out radiators (without power cleaner). Works a treat- they've since been silent and run smoothly. Used F3 again this year as a precaution.
