Here’s a step-by-step guide on how to clean your cast iron radiator:
What you’ll need:
- Drop cloths or plastic sheeting to cover the floor
- Soft bristle brush or vacuum cleaner with a brush attachment
- Radiator cleaning brush or a long stick
- Mild detergent or a specialist cast iron radiator cleaner
- Sponge or cloth
- Bucket of warm water
1. Turn off your cast iron radiator
Before making a start on cleaning your cast iron radiator, make sure it’s switched off and is cool to the touch.
2. Vacuum the radiator
Next, use the vacuum cleaner with a brush attachment and get behind, under and in between the columns of the radiator. Once done, take a drop cloth or some plastic sheeting and position under the radiator. You may also want to protect your walls using painter’s tape.
3. Select the right radiator cleaning brush
A radiator cleaning brush has a flexible design and looks like a chimney sweep tool, making it easier to clean your cast iron radiator. But, if you don’t have a radiator cleaning brush, then you can make your own with little effort. Just take a long stick and wrap a soft cleaning cloth around it, and secure in place with some strong tape.
4. Cleaning your cast iron radiator
Take a bucket and fill it with warm water, and then add in a small amount of dishwashing liquid. Next, dampen the radiator brush or cloth and start to clean between the columns. You’ll be surprised at how much dirt and grime comes on to the brush and falls on to the plastic sheeting on the floor. Once you’ve thoroughly cleaned the radiator, take a separate dry clean cloth, and dry the radiator, ensuring it’s completely dry to prevent rust from developing.
If your cast iron radiator is not working effectively after a good clean, then you may need to call out a plumber to carry out a power flush. This will remove any sludge that’s built up inside the columns and get your radiator working to its full potential once again.
