Boundless Terp Pen XL Cleaning Guide: What you’ll need

You’ll only need a few household items to get going with this cleaning.

  • A few cotton swabs
  • A paper towel
  • Rubbing alcohol
  • Small ziploc bag for soaking


The Terp Pen XL comes apart into a number of pieces. Start by removing the cap and unscrewing the storage compartment. We’ll throw these in for a soak, so set these aside for now. Rotate the coil and mouthpiece counter clockwise to remove them and set them aside for later. Then, unscrew the outer sleeve to reveal the sticky airpath. Finally, unscrew the mouthpiece.

Claim the reclaim (optional)

Depending on the state of your Terp Pen XL, you may have a sizable amount of sticky goodness around the airpath to reclaim. This next step isn’t necessary, but it may provide a session or two that’ll pack a punch. Grab a small stir or concentrate tool and scrape up the goop into a single ball, and throw it into a stash or onto some wax paper for later use.

Soak and wipe

Most of the cleaning is in the soaking phase, with just a few additional steps. Take the coil, outer sleeve, the storage compartment, cap and mouthpiece, and throw them into your ziploc bag. Fill it up with just enough alcohol to submerge them and let them soak for an hour or two.

Then, take a damp cotton swab and wipe in and around the threading where the coil sits. Once all of the other pieces are done soaking, give them a good rinse and set them out to dry.

Clean out the internal vapor path

Under the mouthpiece lies a small vapor path that we’ll want to clean out as well. It’s too small for a cotton swab to get into so we’ll have to get a little creative. Grab your paper towel and twist one of the corners until it's long and small enough to fish into the air hole.

Then, place just a few drops of alcohol onto the tip and feed it into the airhole a few times to clear out any gunk. Once it’s nice and clean, dampen the paper towel with some water and fish it back in to clean out any leftover alcohol.

Run a burnoff with the coil, then reassemble

Once all the pieces are dry, let’s get it ready for some action. We'll want to run a burnoff first, so grab the mouthpiece and coil, and screw them back into place. Then, take a few good draws to activate the heater. You may hear some crackling as it cleanses itself, but that’s alright. It’s good to go when there’s no more visible vapor and it's free of any cleaning smells. Then, take the outer sleeve and screw it back onto the body, followed by the cap and storage compartment. That’s it!

For a cleaner vape...

To keep your Terp Pen XL in top condition for longer stretches, get in the habit of wiping down the airpath with some rubbing alcohol and running a burnoff after a few sessions or so. Most of the buildup occurs here, so a quick, occasional cleaning will help it look and smell fresh longer.

To make cleaning easier, a good rule is to load only what you’ll use, and nothing more. A lot of the buildup comes from leftover material that didn’t get finished off beforehand.

Boundless Terp Pen XL Tips and Tricks: A few tips

The Terp Pen XL is a vaporizer that requires very little effort to enjoy. We spent ample time with it and came up with just a few tips to enhance the experience a little more.

Use it on glass

We mentioned it in our Full Review, but we want to emphasize the Terp Pen XL’s glass compatibility. Connect the mouthpiece end to your glass, remove the cap, and let her rip. For more flavor, scrape it onto the coil and then hit it. For a more traditional experience, inhale to engage the heater, and then scrape it onto the coil to vaporize it in one quick go.

How to load it for travel

If you’re heading out on a trip and plan on taking your Boundless Terp Pen XL with you, why not have a load ready to go as soon as you are? You should be able to press your concentrate material onto the coil, but if it won't stick, give this a try.

With your concentrate at the ready, take a short puff to engage the heater, and place your material onto the coil. You don’t want it to get too hot or it’ll vaporize off. Just warm enough to melt and set it into the coil. Now you’re preloaded and ready to go!
