Remove The Heater Cover

The first step of the cleaning process is to remove the cover of the heater. This will allow you to clean the interior of the device, where the dirt and dust will accumulate. First, you will need to make sure that the heater has been turned off. This will ensure that you don’t get burned by the heating elements. You should also make sure to wear gloves. Sometimes these heating covers can have sharp edges, and you don’t want to accidentally cut your fingers.

Next, take the bottom of the cover and try to lift it, pulling it forward. If it gets stuck, you might want to give it a few taps with a rubber mallet. Once you’ve lifted off the heater cover, take some time to investigate its condition. If you see any rust you might want to consider replacing the cover.

Vacuum And Pressure Clean

Next, you will be able to start cleaning the heater. You should start by trying to remove as much debris as possible by hand. For example, you will be able to remove any larger clumps of hair. Next, you will need to use a vacuum cleaner. This will let you get rid of the smaller debris. To make sure that you don’t damage any delicate internal mechanisms, you should use a soft attachment head. Once done, you can finish off the cleaning process by using a pressure cleaner. This will get rid of any stubborn dirt stains, keeping the fins clean. Once you finish the pressure cleaning process, leave the heater fins to dry off.

Using a pair of pliers, get a firm grip on the bent fin. Then, slowly and carefully apply pressure, straightening it out. You should repeat this process until all the fins are straight. You can also take the time to inspect the inner workings of the device. This can the perfect time to spot parts that need to be replaced and take pre-emptive action before they break. Make sure that the fins are completely dry, then replace the heater cover.

Remove Potential Problems

The inside of a baseboard heater can easily get clogged up with debris, especially if it hasn’t been cleaned in a while. There are a few things that you can do to reduce how frequently you need to clean the heater. A key part of this is the way that you design the room. If possible, try to keep things that can produce a lot of debris away from the heater. For example, you shouldn’t put a pet mat near the heater, as it can get it clogged up with hair.

Repeat At The Start Of The Season

For this reason, you should do this at the start of each winter. Then, as the weather starts to warm up, you should clean the unit again. By doing this, you’ll be able to extend the lifespan of your device, saving you money over the long-term.
