Why Does My Vape Smell Weird?

If you're asking yourself, why does my vape smell weird, the first step to finding a solution is to think about when the smell occurs. This will help you narrow down which part of your vape is the one causing the issue and you can fix things from there.

Ask Yourself If It Happens:

  • Immediately after heating?
  • Only during inhalation?
  • While charging?
  • After long periods without cleaning?
  • After storing for a while?

The timing is the easiest way to identify the source of the odor (other than your nose) and will help you diagnose the issue with a lot more ease.

For example if you notice a burnt vapor smell right after you’ve just used your vape it could indicate that you’ve dialed up the temperature too high. Or if the odor is noticed after cleaning your vaporizer, it could be the result of leftover moisture and cleaning supplies.

So make sure to give things the once over before moving onto the next steps in fixing your smelly vaporizer.

Most Common Causes Of A Smelly Vape

If your vaporizer suddenly develops an unpleasant odor, the first thing to check is cleanliness.

As you use your vaporizer, tiny amounts of residue collect inside the heating chamber, screens, airflow path, and mouthpiece. Over time, this buildup can begin to cook every time you heat your vaporizer, creating an unpleasant vaporizer bad smell that becomes stronger with each and every session.

Fortunately, this is also one of the easiest problems to solve. There are only so many reasons why your vaporizer could possibly smell bad and by running through the breakdown below you’ll see all of the most common examples.

By running through these common causes you’ll be able to rule out 99.99% of odor issues and help ensure you can stop and smell the roses while vaping, all without the risk of a ghastly smell interrupting your fragrance enjoyment.

1. Old Material Left Inside The Chamber

We get it, life can get incredibly busy and sometimes you end up forgetting a pack of dry herbs in your chamber. It’s all fine and dandy until fast forward a few days when you go to use it and it’s got an odor that would put a barnyard to shame.

This is because old materials (dry herbs, concentrates) sitting inside a vaporizer continue drying out and collecting residue even while you’ve forgotten about it. Thus the next time you heat the chamber, that old material can create unpleasant odors that affect both flavor and aroma.

That’s why we recommend avoiding all of this by simply emptying / cleaning out your chamber after you’ve completed your sessions.

Without the power of time on its side, knocking out your spent materials will be far easier and take a fraction of the time. So spend a few seconds now and you’ll be saving double time later when you don’t have to clean out a smelly old chamber.

2. Residue Inside The Mouthpiece

The vape mouthpiece is one of the most overlooked parts of any vaporizer. Every draw pulls not just tiny amounts of vapor through the airway, but also ends up mixing with backwashed saliva that if ignored, can become smellier than a blue cheese convection in August.

Thus over time sticky residue will collect inside your mouthpiece and can sometimes lead to foul odors coming from your vaporizer.

If you notice this it means it’s time to break out the isopropyl alcohol and give your mouthpiece a full on bath. This way you can permanently delete lingering bacteria, materials, and other smelly goodies that are lingering to give your mouthpiece a fresh start.

With a quick clean your mouthpiece should be all good to go, however in the most extreme cases you can always look for replacement components like the Wulf Faze Replacement Mouthpiece.

3. Clogged Screens

Not only can your mouthpiece feel the stress of heavy use, but so can your screen which when clogged can eventually become smelly in just the same manner.

This is where taking your screen out and giving it a good clean comes in handy. It may take a while, but with enough elbow grease and isopropyl alcohol you’ll have your screen back to factory form in no time.

This won’t just eliminate any odors, but also give you proper airflow to ensure your ripping clouds are as big as possible, all without having to feel like you're drawing a golf ball up a garden hose.

4. Excessive Temperatures

Another reason for bad smelling vaporizers is excessive temperatures leading to burnt materials that smell and taste terrible. This is often because you’ve turned things up too high for your specific type of material, resulting in it being over exposed to heat.

While higher temperatures produce:

  • Warmer vapor
  • Larger clouds

They can also increase:

  • Residue buildup
  • Burnt flavors
  • Lingering odors

Experimenting with slightly lower temperatures often improves both taste and smell in an instant, all without requiring any lengthy cleaning process.

So if you do notice things tasting and smelling burnt, then it’s time to crank down the voltage / temperature level and see if a little bit of a cooler setting doesn’t solve your issue. Lowering your temperature slightly can also improve flavor as a nice bonus.

How To Remove Vaporizer Smell

Wondering how to remove vaporizer smelliness completely?

Well as a general catch all, we wanted to round out our usual suspects of smelly vapes by reminding you that dirtiness is often the real culprit. Thus don’t Kaiser Smelly walk out the front door and make sure you break out the cleaning supplies on every last component of your vape.

When it comes down to how often you should clean your vaporizer, we recommend doing so as often as possible. Honestly it makes things a million times better for your vaporizer, so never let things go longer than a few weeks without a deep clean to avoid all of these smell issues.

We can’t tell you how many times we’ve seen this fix our friends' vaporizer odor issues, making this one of the most effective methods of not just eliminating current smell issues, but dodge them in the future.

Follow these basic steps:

  • Empty the chamber.
  • Remove loose debris.
  • Clean removable parts.
  • Wipe the chamber carefully.
  • Clean the mouthpiece.
  • Allow everything to dry completely.

Once reassembled, many vaporizers immediately return to their normal fresh flavor.

Could The Material Be The Problem?

Sometimes your vaporizer isn't responsible at all. Old, overly dry, or poor quality material can produce unusual smells even in a perfectly clean vaporizer. Due to their low quality and age, they end up burning unevenly as well.

In other cases you may just have some very cheesy dank herb that absolutely reeks, in this case you’re just going to have to lock in and rip the clouds while embracing the flower odors to the fullest.

If you've cleaned everything thoroughly and the odor remains, consider trying fresh or different materials before assuming something is wrong with the vaporizer itself.

When Should You Be Concerned?

Most odors are harmless maintenance issues.

However, stop using your vaporizer immediately if you notice:

  • Electrical burning smells
  • Melting plastic odors
  • Smoke coming from the battery
  • Swelling batteries
  • Visible damage

These situations are very different from normal chamber residue and should be addressed before further use. Check out our common vaporizer troubleshooting tips here to learn how to deal with all of these issues in more depth.

Preventing Bad Smells In The Future

Keeping your vaporizer fresh is mostly about consistency.

Develop these habits:

  • Empty the chamber after every session.
  • Clean regularly.
  • Store your vaporizer in a cool, dry location.
  • Avoid overheating material.
  • Replace worn screens and mouthpieces when needed.

These simple steps go a long way toward preventing unpleasant odors.
