Is this a clear liquid or not and does it matter??
on 2 January 2016
I purchased 2 of these Fernox inhibitors separately. The first was not a clear liquid but a rusty brown colour. When I received my second, in order to top up, the colour of this was clear and I checked that the product should indeed be clear. Both (identical?) are now in my central heating system though I have doubts about what it says it should do on the bottle.
Both bottles were properly sealed when I received them.
