How To Unclog a Vape Cartridge That Has No AirFlow

A clogged vape pen is one of the most common problems that vapers face. This can be caused by various things, from build-up in the tank to moisture in the air.

No matter the cause, it’s important to know how to clean a clogged vape so you can enjoy vaping your favorite juice.

Why Do Vape Cartridges Clog?

The clogging issue is usually noticed in Delta 8 THC vape cartridges. It’s because CBD vape juice comes in different milligram strengths.

It indicates the various strength of pure hemp oil extract in the e-liquid. Hemp oil is a thick and dense material that increases the overall thickness of e-liquid in the cartridge.

High viscosity leaves residue on the air vent hole; over time, this build-up clogs the vape cartridge and prevents airflow.

This is the most common reason why a CBD vape cartridge clogs and won’t hit.

Also, if your vape battery health is degraded, it won’t heat your coil to a sufficient temperature, and the vape cart will clog.

But you can unclog your vape cartridge at home by trying some easy methods. We’ll learn the various tricks to unclog a vape cart.

How To Unclog a Vape Cartridge?

There are different ways to clean a clogged vape, depending on the severity of the problem.

Let’s find out some easy tips and tricks to unclog your Delta 8 vape cart or any other vape cartridges-

1. Preheat your vape


Many disposable Delta 8 THC vapes come with preheat functionalities. If your CBD vape cartridge is clogged, then press and hold the preheat button for 15 to 20 seconds.

Preheating will decrease the hemp oil viscosity, and the build-up breaks down and settle into an e-liquid cartridge. Now, wait for 5 to 8 seconds and take a drag.

If your vape pen has no preheat button, you can try some easy tricks to heat your vape cartridge and fix a clog.

Remove your cartridge from the vape pen and wrap it in a cotton cloth. Now, set your microwave to preheat function and put your vape cart in the microwave for 1 to 2 minutes.

Make sure you do not set the high temperature on the microwave else, it will damage your vape cartridge.

Another trick you can use to preheat your vape cart is to pack it in a water-tight bag and submerge it in the hot water bath for a few minutes.

After removing it from the water bath or microwave, keep it upright for a few seconds to let the e-juice settle. Then take a gentle drag to see if your vape is unclogged or not.

2. Blow some hot air

If your vape cartridge is slightly clogged, you can blow some hot air on it to fix the problem. Get a hair dryer and put it on hot mode.

Now, hold your cartridge close to the hair dryer nozzle and blow some hot air for 60 seconds.

The heat will help to break down the oil build-up and unclog your vape cartridge.

3. Pull hard through the mouthpiece

If your vape cartridge is still clogged after trying the above methods, you can pull hard through the mouthpiece to unclog it.

Remove the cartridge from the vape pen and put your mouth on the mouthpiece. Now, take a deep breath and see if any air is passing through. If yes, then your vape is unclogged.

4. Full charge your vape

Charge your vape pen

Don’t wait for the charging indicator to blink. Plug your vape pen into charging before the battery completely drains.

Low power wattage will not deliver enough power to your coil and won’t evaporate viscous e-liquid.

Fully charge your battery and take a hard hit to unclog any residue build-up. If it doesn’t break the residue buildup, try the next method.

5. Dislodge buildup manually

If you’ve tried all the above methods, but the airway is still blocked, and your disposable won’t produce vapor, it’s time to unclog the cartridge manually.

First of all, disassemble your vape cart from the pen and use a safety pin or wire to break the build-up. Try to remove the thick layer formed on the hole to restore the airflow.

How To Prevent Vape Carts from Clogging?

The best way to prevent your vape cartridge from clogging is to clean it regularly. Also, you should avoid using low-quality or cheap vape cartridges as they are prone to clogging.

1. Take smaller hits

Inhale gently and take smaller hits. If you take large hits, then it will flood your coil and will clog your cartridge.

If you are using a vape cartridge filled with high-strength hemp oils, then it will gradually clog your cartridge. So, it’s better to use low milligram strength of CBD in your vape juice.

2. Keep the mouthpiece clean

The mouthpiece is the part that comes in contact with your mouth. So, it’s important to keep it clean.

You can use an alcohol swab or cotton swabs dipped in isopropyl alcohol to clean the mouthpiece. Regularly cleaning the mouthpiece will prevent residue buildup and clogging.

3. Take dry hits

A dry hit is when you take a drag from your vape pen, and no vapor is produced. So, after cleaning your vape, it’s recommended to take a few dry hits to remove any moisture before vapor production.

4. Do not leave your vape in a cold place

Leaving your vape in a cold place will make the oil thicker and clog your cartridge. So, avoid using your vape in cold weather or storing it in the fridge.

5. Keep your vape in an upright position

You should also store your cartridge upright when not in use. This will prevent the residue from building up over the coil and air vents. Otherwise, your vape pen cartridge will be jammed or clogged.

6. Avoid flooding

Vape flooding is a major reason for condensation buildup in the cartridge. It leads to clogging your vape cart. So, always go slowly and avoid flooding your vape coil with e-liquids.

7. Take a hit every few days

Leaving your vape pen unused will lead to clogging. If you’re going to store it for longer durations, it’s better to take a hit every few days.


If your vape cartridge is clogged, then you can use the above methods to clean it. Also, you should regularly clean your vape and take small hits to prevent clogging.
