One common issue with radiators is that they get clogged up with dirt and dust over time, which can cause your home or office to feel colder than it should be. Below are some tips on how to clean the fins of your radiator so that your home feels warmer this winter!

In this post, I will be sharing with you some tips on how to clean radiator fins so read on…

How To Clean Radiator Fins?

Do you have a radiator that needs cleaning? It’s easy to do with just an inexpensive product from your local supermarket. All you need is baking soda, water and vinegar!

Here are the simple steps:

  1. Pour about 3 cups of baking soda in the bottom of the radiator. Add enough water to make it gooey but not too liquidy. Mix well with a spoon or spatula. Let sit for 30 minutes while releasing heat into the air (or until it hardens). This step helps to loosen up all the built-up dirt, dust and grime forming around the radiator.
  2. Once it’s hardened (or at least dry enough to not sink), pour about 3 cups of vinegar in the same area you poured baking soda. Since vinegar is very acidic, it will dissolve all the gunk that has accumulated over time. Let sit for another 30 minutes while releasing heat into the air (or until it hardens).
  3. Do not let this solution evaporate before 30 minutes are complete! If needed, add more baking soda or vinegar to keep consistency. This step helps to dissolve away all that dirt and grime so you can remove it easily with a towel later on!

*Pro Tip: Use an old towel or a paintbrush to apply the solution. This will help you keep from removing too much of your radiator’s lovely finish.

  1. Once 30 minutes have passed, use a vacuum to suck up all that loosened dirt and grime! Wipe down any remaining residue with a moist towel and finish with a dry one. Dump out any remaining liquid and wipe off excess powder on top with paper towel or rag. -Next, mix 1 cup of vinegar into 2 cups of water in a bucket or large bowl, then pour over clean residue free radiator. Let sit for 30 minutes.

I personally used almost ¾ cup baking soda and just over 1 cup vinegar, which only made the bottom of my radiator wet (not enough to see) and left some residue on top (easy to wipe away). It took about half an hour before my radiator was completely dry again, after which I placed a fan in front of my radiator to speed up the process.

Remember to unplug your radiator before cleaning it!

How do you clean dust off radiator fins?

One of the most effective ways to clean dust off radiator fins is to use a squeegee and any form of liquid dish soap.

Using the squeegee on top of each radiator fin, work it from one end to the other in an up-and-down motion so that the dust is pushed down into the fins.

Once you’ve finished with all your radiator fins, go over them again with a clean cloth soaked in soapy water and gently wipe away any remaining dust stuck between the fins.

Leave your radiator to dry for a few hours before turning your heat back on.

How do you clean central heating radiator fins?

Using a small brush, gently dust off any large particles of dirt that may be stuck between the fins.

Fill up your pressure washer (or bucket) with clean water and add about 30ml (2tbsp) dish soap to it.

Place the end of your pressure washer hose next to one of your radiator’s air vents and turn on the water until everything is running smoothly.

Then, use the pressure washer or garden hose to wash away all dirt at least 2 feet away from your radiator in both directions.

If there are only a few spots of dirt you’d like to attack, try spacing out your spray so as not to make a mess everywhere! Once finished, run a dry rag over the fins to ensure no water remains.

How should you clean a radiator?

  1. Make sure the radiator is not still hot and unplugged before cleaning it! And if it’s made of steel or copper, wipe away any dirt first with a dry cloth as those materials are easily damaged by liquid soap.
  2. Use a small brush to remove any large particles of dirt that may be stuck between the fins and then use either dish soap and water or just plain water to wash your radiator from top to bottom using a rag or squeegee.
  3. Be careful not to push down too hard on your central heating radiator as it can break or collapse the fin/radiator core if done incorrectly causing permanent damage! there is anything stuck in between the fins.
  4. Let your radiator dry completely before turning it back on and make sure to check for any damage or leaking pipes/pads before doing so!

How do you clean a white radiator?

To clean your white central heating radiator, take down your curtains, blinds, pictures etc to prevent water getting sprayed over them when cleaning.

Next, unplug your radiator and give it a quick wipe down with a cloth in order to remove any loose dirt that may have come off while moving the furniture away from above your radiator(you can also use this time to inspect all of its valves in case there is anything wrong).

Once done, mix about 30ml (2tbsp) dish soap into 2 cups warm water and then fill up your bucket.

Place the end of the heat washer’s hose next to one of your radiator’s air vents and turn on the water until everything is running smoothly, making sure to spray every single part of your radiator thoroughly (as some parts will not get wet when using a squeegee).

When done, use a clean rag to dry off any remaining excess water and let it fully dry before putting back together and turning on.

Hope this helps! 🙂

How do you clean a clogged aluminum radiator?

Use your aluminum radiator clog remover and place it over the holes of your radiator.

Then, turn the valve on to start pushing water under pressure into the hole.

When there’s enough pressure, you should hear a noise when the clog is sent down whatever pipe or drain that might have caused this issue in the first place! The clog remover will then fall out, making way for the water to flow freely again through your central heating system.

If this doesn’t work, try using an alternative tool such as a wire coat hanger in order to fish out any other objects stuck within your radiator.

What are radiator fins?

Radiator fins are slats of metal that have been perforated with a large number of small holes to allow heated air from the radiator to transfer heat to a room.

If you use your central heating system a lot, dirt and dust tend to build up inside these fins which can lead to reduced performance over time as well as possible dust explosions! To reduce this risk, we recommend investing in an aluminum radiator clog remover or one like it as it enables you to remove any blockage by simply attaching the tool onto your radiator and turning the water pressure on for about 10 seconds.

Be sure not do turn your central heating system back on before clearing out any dirt/dust that’s clogging up your radiator as you could risk burning yourself on the hot surface!

Do radiators need replacing if their fins break?

If you notice small holes or rust spots, don’t panic! You’ll probably only need to replace your radiator for aesthetic reasons. But if it has significant damage, make sure to call a professional instead of trying to fix it yourself.

One of the key reasons as to why radiator fins break is corrosion! If your radiator is out in the open and it’s exposed to water or excessive amounts of humidity, this will cause it to rust.

Preventative measures include: making sure that you’re using a tool such as an aluminum radiator clog remover on any debris that might be stuck within your radiator and turning the central heating system off before inspecting for damage and/or replacing its valves.

If you notice any discoloration on your fins after calling a professional, make sure to give them all the information about what’s been happening with your central heating system as it may affect how they work their magic! 🙂
