While radiators don’t take up a lot of space in your home, they can be a bit tricky to dust and sanitize from time to time. Thankfully, there are plenty of ways to get rid of the dust hiding in the nooks and crannies. If you’re having extra difficulty cleaning in or behind your paneled radiator, try removing the panels to give yourself better access to the dusty areas.

  1. Find a valve on the right or left side of your radiator. [1] Some valves will be labeled from 0 to a higher number, while other valves won’t be labeled at all. Depending on your radiator model, twist the valve so it reads “0,” or turn the valve clockwise until it doesn’t turn anymore. Once you’ve done this, wait for the radiator to cool down completely. [2] [3]
    • It might take several minutes before the radiator is cool to the touch.
  2. [4] Connect a canister or hose attachment to a traditional vacuum cleaner. Turn the vacuum on as you normally would, then stick the hose behind the radiator. Move the attachment back and forth so you can get rid of any heater dust that’s stuck to the radiator. [5]
    • Don’t worry if your vacuum doesn’t fit in or around the radiator fins—just do the best that you can!

  3. Check online or visit a home goods store to find a long, flexible microfiber brush that can fit into the nooks and crannies of your radiator. Stick the brush in, around, and behind the radiator to clean and brush away any dust. [6]
  4. Drape an old towel beneath your radiator to catch any wayward dust trickling out. Once the towel is in place, plug your hair dryer into a nearby wall socket, then turn it on to the highest heat setting. Move the hair dryer back and forth along the top surface of the radiator. Continue using your hair dryer for a minute or so, or until a lot of dust spills onto the towel. [7]
  5. Find a sturdy, shatterproof ruler that can fit in the slats or fins of your radiator. Take a dusting cloth and wrap it around the ruler several times, then stick the dusting cloth into the nooks and crannies of your radiator. Focus on any spots that look especially dusty, and replace the cloth as needed. [8]
    • You can purchase dusting clothes online, or in any place that sells cleaning supplies.
    • You can also use a ruler and dusting cloth when the radiator grill is still attached.
    • If your radiator is especially large, consider using a broom handle instead. [9]

    Tip: Use a piece of tape to hold your cleaning cloth in place. [10]

  6. Fill a bucket or basin with warm water and mix in a blueberry-sized amount of dish soap or all-purpose cleaner. Dip your sponge into the mixture, wring it out, and clean off the outside of the radiator. Try to wipe off the whole exterior to ensure a thorough clean. [11]
    • Dry the radiator once you're done
  7. [12] Dip the sponge into the soapy mixture and wring it out again. Use the damp sponge to clean the wall above the radiator in case it’s collected any dust. Don’t saturate the wall with cleaner—instead, just give it a quick wipe down. [13]
    • Use a clean towel to dry the wall.
  8. Reverse the process you used to turn off the radiator so you can use it again. Make sure the entire radiator is dry before you do this, though.

Disassembling and Reassembling a Paneled Radiator

  1. Find the valve or dial along the side of your radiator and check the display. If the valve has a numbered display, make sure that it’s turned to 0. If the dial doesn’t have any numbers, turn it clockwise until it can’t rotate anymore. [14]
    • Make sure the radiator is cool to the touch before you start disassembling it.
  2. Find 2 large washers sticking out from both sides of your device. Balance your thumb on the top edge of the radiator, then place the rest of your fingers beneath the water. Pull upwards on the side panel until you’ve disconnected it from the rest of the heater. [15]
    • You’ll need to remove both side panels before you can take the top grill off.
  3. After taking off the side panels, use both hands to pick up and move the top grill to a separate spot. With the side panels gone, there won’t be anything holding the top grill in place, which makes it easy to move around. [16]
  4. Search along the center of your top radiator grill to see if there’s a plastic clip holding the grill in place. If there is, slide a flathead screwdriver into the radiator and rest it behind the clip. Place another flathead screwdriver beneath the short end of the top panel, then push upwards on the handle to free the grill from the radiator. [17]
    • If your radiator doesn’t have a clip, you don’t have to worry about this.
    • Pretend that the second screwdriver is a crowbar that you’re using it to pry the single panel off of the grill.
  5. With the top part of the radiator open, brush along the surface of the fins to get rid of any visible dust and grime. Move the duster back and forth on the fins until the metal looks clean and dust-free. [18]
  6. Arrange the top grill over the surface of the radiator. Align each side panel over a large washer, then push both panels into place. [19] If you’re working with a single panel radiator, re-align the top grill over the top of the radiator and push it into place. After this, you can push the side sections of the radiator beneath the top grill. [20]
    • Restore power to the radiator once you're finished.

    A hose extension on a vacuum works well! If you don't have that kind of equipment, create a homemade duster by tying a rag to a broom handle.
