Figuring out how to clean a baseboard heater isn't very difficult, but it might be something you're unfamiliar with if this type of heating is new to you. Check out how to clean a baseboard heater below.

Things You'll Need

You likely already have what you need to clean your baseboard heater at home. Grab these things before you get started:

• A vacuum with a brush attachment
• A pair of needle-nose pliers
• A soft cloth
• All-purpose cleaner or soapy water

Step-by-Step Instructions

Step 1: Shut It Down

You don't want the heater running while you're cleaning. If it's been running, give the unit time to cool before you start working.

Step 2: Pop Off the Baseboard Heater Cover

The parts that need to be cleaned are hidden behind that cover. You can typically pull it off without any tools by lifting from the bottom and pulling the cover toward you. On some models, you might have to remove the end caps first or unscrew the cover. Set the cover aside out of the way while you work.

Step 3: Vacuum the Inside

You'll want to focus mostly on the fins inside the unit, which is where dust tends to collect. Use the brush attachment to gently remove any debris between the fins. Continue vacuuming any other areas inside the baseboard heater, as well as the floor below it, to get rid of any debris.

Step 4: Straighten Up the Fins

Check for any fins that are bent, even a little. Air can flow more freely when the fins are straight. Using your needle-nose pliers, bend the fins back to their correct position. Keep in mind that the fins are sharp, so work around them carefully.

Step 5: Wipe Spots if Necessary

If you see any dirty areas that didn't come clean with the vacuum, use a slightly damp cloth to wipe those areas.

Step 6: Clean the Cover

You can use an all-purpose cleaner or soapy water to clean the baseboard heater cover while it's off the unit. Dry it well after you're done cleaning it.

Step 7: Replace the Cover

Position it back on the heater once it's completely clean and dry. Reattach it with screws, put the end caps back in place or do other tasks to attach it based on your model.

Step 8: Test the Unit

Turn the power back on and adjust the thermostat to make the heater run. Verify that it's working correctly.

How Often Do You Need to Clean Your Baseboard Heater?

It's a good idea to clean your baseboard heater at least once per year. Doing it right before the heating season gives you a fresh start and helps the system run well while it's cold outside. You might need to perform a baseboard heater cleaning more often if your home is particularly dusty or you have pets that shed a lot of hair. Clean the unit sooner if you can see visible dirt and debris building up on it. Cleaning might also help if the heater smells funny or it's not heating as well as normal.

What Other Maintenance Do You Need to Perform on Your Baseboard Heater?

Cleaning the unit is the main baseboard heater maintenance task you'll need to perform. However, you might need to do a few other maintenance tasks, including regular inspections. Make sure nothing is blocking the unit. It's also a good idea to look under and behind the heater to make sure nothing falls back there. Dusting the outside of the unit weekly can help keep the interior fins cleaner. If the heater stops working correctly, you might need to do some light troubleshooting to see if you can correct the issue before calling a repair service.
