Why does my weed pen clog?

Restricted airflow, decreased vapor production, and altered flavor are all indications your pen might be clogged. 

Here are some of the main causes: 

Using too-thick e-liquid 

If the weed oil is too thick for the battery, it’ll be hard to vaporize it, clogging the airways. 

Residual buildup 

Continued use of a weed pen can lead to accumulation of moisture and oil near the mouthpiece, leading to clogging. Also, the residue can settle on the heating element or airway, blocking the vapor flow. 

Moreover, the oil will heat excessively when taking long and continuous draws. This thinner the oil, which rises into the mouthpiece, mixing with small particles in the air, such as dust, leading to stinky gunk.  

Poor storage 

Poor storage conditions can lead to blockage, especially after a prolonged period. For instance, if you store your pen in cold temperatures, the oil will thicken, leading to clogs. On the other hand, high temperature can cause oil thinning, leading to leakage and clogging.

Worn out components 

A weed pen comprises several components that must be in top-notch condition to work efficiently. Any damage to the parts will disrupt the flow, leading to blockage. For instance, a worn-out wick may lead to incomplete vaporization and blockage.

Now that you know what could be causing the clog, let’s discuss how to fix it.

Preheat the weed pen 

Sometimes, all you need to do is preheat the oil to a point where the consistency is optimal. 

If your pen is draw-activated, inhale slowly to heat the oil. However, you should be careful with this option as it can lead to a ‘dry burn,’ which can ruin your precious oil. If you have a button-activated one, press the button to preheat the oil before taking your first draw.

Cleaning the weed pen

If the above solution doesn’t work, this might mean that your pen is due for a cleaning

Assembling the materials 

You’ll need: 

  • Paper towels
  • Cotton swabs 
  • Isopropyl Alcohol
  • Toothpick 

Prepare the workstation 

Ensure you’re working in an open space with enough air circulation. Alcohol vapor can cause issues such as headaches. Also, it’s highly flammable, so avoid using it near open fires.

Next, carefully disassemble the detachable components, including the mouthpiece, cart, and battery. 

Clearing the Airflow Pathway

Inspect the airflow vents for any visible buildup. Use a toothpick to dislodge any visible obstruction gently. 

If the clog persists, dampen the cotton swab with isopropyl alcohol and clean the stubborn debris. 

Next, soak the mouthpiece in warm water for at least 15 minutes. Then, run it under water to clear away the dislodged debris and let it dry in an open space. 

Cleaning the Cartridge

Start by removing any excess oil from the cart. Then, clean the connection point where the cartridge connects to the battery to remove buildup. 

Soak the cart in isopropyl alcohol for 20 minutes to dissolve the debris. However, avoid submerging it completely if it has a non-detachable battery and electronic components. Instead, use a Q-tip to dislodge any gunk. 

Run it under running water to remove any alcohol residue, which can affect your favorite strain’s flavor, and let it dry before reassembling.

Reassembly and testing

Once the components are completely dry, carefully reassemble them, taking care not to damage them. Most weed pens have a 510 thread. Thus, it’ll be easier to screw the parts back. 

Put fresh e-liquid and test your now clog-free pen. If there’s an issue, repeat the process until you’re satisfied with the results. 

Maintenance tips to prevent future clogs

Preventing future clogs will save you a considerable amount of time and effort. 

Regular cleaning 

Cleaning your weed pen routinely will help prevent clog buildup. Use Q-tips to remove any signs of residue. 

Use quality concentrate 

Quality e-liquid designed for weed pens reduces the risk of clogging. A low-quality one might contain impurities, which can clog the airflow after continued use.

Avoid overfilling the cartridge 

When you overfill the cart, the oil might spill and block other crucial components, affecting the flow. 

Ensure Your Vaporizer Maintains A Steady Flow

A clogged pen will not only affect your strain’s flavor but also may lead to a dry burn. Cleaning it ensures you have a clog-free pen to draw smooth hits.
