Hi all

The kichen saga continues..
The kitchen radiator was long since removed, to give access for wiring
chases etc.
It was moved to the garage probably 4-6 months ago.
Although the inlet/outlet ports were covered, it is likely that some rust
has formed inside the rad.

Due to slow progress and the likelihood of colder weather, I am considering
re-fitting the rad to take the chill off.
This would also allow testing of the new feed piping I am working on for a
kick space heater.

So, is there anything that can be done to "rinse out any rust" from the
radiator before re-fitting?
It is not an old tatty thing - moderish stelrad type bog-standard item.

Thanks

Phil

Assuming your cold water pressure is reasonable, connect a hosepipe to
each port (alternately, and several times), and give it a good blasting
until the emerging water is clear?

Thinking about it further, I believe that various 'colas' contain
phosphoric acid - the active ingredient in de-rusting materials like
'Kurerust'. They can be used to remove surface contamination and
corrosion from metals. You might like to experiment with a piece of
rusty metal.

If it works, to really get rid of all the internal surface rust, you
could try filling the radiator with a bottle of cola. Make sure you use
the 'Real Thing'! ;o))

Plug one end, stand on that end, fill with cheap cola and leave for a
weekend, the phosphoric acid in it will dissolve the rust and passivate the
inside surface with iron phosphate in its place? Then rinse until the kids
can't drink any more...

Sounds interesting, but what effect/reaction does any residual Cola or iron
phosphate have with system inhibitors etc.?
