Car air freshener comes in many forms. They can be in a car vent clip, plugin, or just with the glass or plastic container. 

Before you get started with the process, you should check the smell of the oil that you’ll use. Warming the oil gives the fragrance more strength so it can penetrate everyone’s nose. Just like its forms, there’s more than one way on how to do the refill. Here are three possibilities and you can choose the one that is convenient for you. 

Air Freshener Refill Using Eye Dropper

You have to use the car clip diffuser, which is made in stainless steel and, of course, refillable. You can also recycle an empty vent clip air freshener and add the oil for a non-toxic product.

Other things that you need are eyedropper and a huge embroidery needle. 

Necessary Steps:

1. Use the embroidery needle to make a hole of the top of an empty air freshener.

2. To fill the vent clip air freshener, use the eyedropper to transport your favorite scented oil. You have to put it on the hole that you made.

It could be messy, so you might want to do it in a large bowl so you can do the cleaning quickly with ease.

3. You can start using it by placing it on your air conditioner or heating the car vent. A good-smelling ride can begin.

Refill with Plug-In

In this method, you’ll need an empty plug in a container, a knife or something that is sharp and thin, and oil warmer’s scented oil.

Steps to follow:

1. Make sure you get the oil that is made for oil warmer. You can also use the oil that you made yourself.

2. Lift the lid cover, which is made from rubber plastic. It is the job of the knife. 

You have to do it with care as you will use the lid later on. The lid can be removed gently and slowly from the glass surface. 

3. Pour the oil into the container once the lid was removed. You have to do it slowly so the oil will be directly dropped to the container. You don’t want to make a mess out of it.

4. Then put back the lid, so the container is sealed tightly. If you have screws for it, you can have them on the cover. 

This process asks for no sweat as after a little time and a few steps; it’s ready to use.

Air Freshener Refill with Container and Wick 

1. Make sure that your container is clean and free of any remains of the previous scent. 

2. Your working place should be covered with cloth or paper towels to catch any instance of a spill. You can use latex gloves when you’re dealing with a strong fragrance.

3. You can take off the plastic cap by your fingers, or you can use a small screwdriver. Use a bit of force, but do it carefully.

You don’t need to remove the wick or even touch it.

4. Refill the container with the help of a funnel with a diameter of half an inch. Pour the oil into the container with enough consciousness to avoid overfilling.

The wick should be given enough air space and volume as over-saturation is not a good thing.

5. The plastic cap with the wick can be placed back. The wick should be in good condition and free of any damage. If not, you have to get another good one and start all over again.

Don’t rinse the wick with water. If you do it, it will swell or even break apart. So leakage can happen. 

6. Put a label on the container so you won’t mix up the scent. It can be used right away.

You have to check on the wick from time to time if there’s damage.
