How to clean cast iron radiators

This is a simple guide about how to clean cast iron and column radiators. These radiators can be tricky to clean with their vertical columns with narrow gaps in between them, which attracts dust and dirt. A small cast iron radiator with 12 columns can take a good half an hour to clean but this is not something that needs to be done every week. If you are not careful dust can really accumulate without you realising leaving a very mucky radiator.

If your radiator is painted, clean it as follows. It’s really important you do not use this method for polished radiators.

Step One

First of all vacuum all over the surface of the radiator using a soft brush to get the surface dirt off. Then wrap a non metal kitchen implement such as a wooden spoon or spatula in a cloth or teatowel and then run this up between the columns over all of the internal surfaces to dislodge the dirt. Make sure the spoon/towel arrangement is fat enough to be squashed into the crevices of your radiator.

Step Two

Vacuum again. If the radiator does not look clean, use the spoon/towel again wherever you see dust and dirt.

Step Three

Fill a bucket with hot water and washing up liquid. Immerse a dishcloth in this water, and then wring out your dishcloth. Place a towel under the radiator. Then use the dishcloth like dental floss in between the radiators columns, up and down, to give the radiator a wash over all it’s surfaces. Rinse out your cloth and then wring it out again in between each set of columns. If the water gets really dirty, discard the water and fill the bucket with fresh water and washing up liquid. Carry on until all surfaces look clean. For any really stubborn stains, you might wish to gently use a toothbrush but don’t rub too hard. You don’t want to rub the paint off.

If your radiator is polished

With a polished radiator, as the bare metal is exposed to the atmosphere, the finish  requires some regular maintenance to eliminate any unsightly surface patina from forming. Every 6 – 8 weeks you should  take a soft lint free polishing cloth, lightly spray it with WD40 and rub it over the polished surfaces of the radiator. This will help to ensure your polished surfaces remain bright and un-oxidised. If the surfaces do start to oxidize, then rubbing them with a Scotch Brite cloth should resolve this for you.
