 Important Safety Guidelines

• Never attempt to modify or tamper with cartridges containing cannabis or nicotine.
   
• Always check your device manufacturer’s instructions before troubleshooting.
   
• Stop using immediately if the cartridge shows cracks, leaks, or damage.
   

Common Causes of Cartridge Clogs

1. Viscosity Changes – E-liquids can thicken in cold temperatures, reducing airflow.
    
2. Residue Buildup – Natural use may cause leftover oil or debris to block channels.
    
3. Hardware Issues – Factory defects or physical damage can restrict proper function.
    

Step 1: Gentle Warming Methods

Thickened e-liquids often cause airflow issues. Gentle warming can restore normal viscosity.

Hand-Warming Technique

• Roll the cartridge between your palms for 2–3 minutes.
   
• Test airflow with soft puffs (do not activate the battery yet).
   

Warm Water Bath

• Place the cartridge inside a sealed plastic bag.
   
• Submerge in warm tap water (max 100°F / 38°C) for up to 5 minutes.
   
• Dry thoroughly before reconnecting to your device.
   

Step 2: Clear the Airflow Channels

If warming doesn’t help, residue may be blocking the airflow.

Toothpick Method

• Identify airflow holes at the base of the cartridge.
   
• Gently insert a wooden toothpick.
   
• Rotate lightly to dislodge buildup—avoid applying pressure.
   

Compressed Air Technique

• Use electronics-grade canned air.
   
• Apply short, 1-second bursts through the mouthpiece.
   
• Wipe away any residue that becomes visible.
   

Step 3: Cartridge Maintenance & Prevention

Keeping your cartridge clean helps avoid recurring issues.

Cleaning the Connection Points

• Detach the cartridge from the battery.
   
• Lightly dip a cotton swab in 70%+ isopropyl alcohol.
   
• Clean the threading and contact points.
   
• Allow to air dry completely before reattaching.
   

Storage Best Practices

• Store cartridges upright at room temperature.
   
• Avoid extreme heat or freezing conditions.
   
• Use protective caps when not in use to prevent dust entry.
   

When to Replace Your Cartridge

Some clogs cannot be fixed. Replace your cartridge if you notice:

• Cracks, leaks, or visible damage.
   
• Persistent clogging even after troubleshooting.
   
• Burnt taste despite proper care and cleaning.
   

Always purchase replacements from licensed and trusted retailers for quality and safety.

Key Takeaways

• Most clogs can be resolved with simple warming or cleaning methods.
   
• Regular maintenance prevents blockages and prolongs cartridge life.
   
• If a cartridge is damaged, cracked, or tastes burnt, replacement is the safest option.
   
• Always follow your device’s manual for model-specific care.
