How to Clean Your Core E-Rig (Without Breaking It)

Keeping your Core clean is most of the battle with these devices. Do it right and it’ll last you a long time. Here’s exactly how I clean mine, part by part — and at the end, how to do a burn-off cleaning to bring a charred heater cup back to white.

First, what comes apart — and what doesn’t. Everything on the Core that’s meant to come off, comes off by hand: the glass comes off its gasket, the metal slide pulls off, and the coil unscrews. That’s it. Nothing needs to be pried, forced, or ripped — so if a part isn’t releasing with gentle hand pressure, it’s not meant to come off, and you can leave it alone. The glass is your airpath, and since it lifts right off, you’ve got full access to clean everything without taking the device apart any further.

Removing the glass

Grip the glass firmly at the base and gently work it off at an angle — never straight up. Pulling straight up can rip the gasket out with it; easing it off at an angle releases it cleanly. Once it’s off, clean underneath it and make sure that area is spotless.

Keep that gasket lubed with a vegetable oil of your choice. Here’s why it matters: if the gasket is dry, the glass can stick to it, and when you pull the glass off it’ll rip the gasket out with it — and that will destroy the device. A lubed gasket lets the glass slide off clean.

Cleaning the glass

Start with hot water. Run it through the glass and flush out as much reclaim as you can first. (The glass isn’t attached to the core for this — it’s its own piece.) Once most of the reclaim is gone, pour all the water out.

The hot water leaves the glass warm, and that warmth is the whole point: warm reclaim is soft and lifts off easy — cold reclaim fights you. So while the glass is still warm and the water’s poured out, add 2–3 teaspoons of table salt and a small amount of rubbing alcohol. Cover all the holes with your fingers and shake vigorously until the rest of the reclaim lifts off. Then rinse with hot water and soap. That’s it for the glass.

The metal slide/sleeve

This is the sleeve that protects the coil. After every session, Q-tip out the cup and wipe down the inside of the metal sleeve while it’s still warm — make sure there’s no reclaim left in there.

Lube the outside of the slide with a vegetable oil of your choice so it comes on and off easily. You want it sliding off effortlessly every time you load the bowl and every time you clean — that’s how it should be.

After every session

Q-tip the bowl. If you see any reclaim on the sides of the bowl or on the metal, wipe it down with rubbing alcohol while it’s still warm. Warm reclaim wipes away easy — cold reclaim fights you.

Every time you charge

Unscrew the coil and look at the area where it screws in to make sure it’s clean. If it’s really dirty: take the glass off, scrape out any reclaim in there, then use rubbing alcohol wipes to clean the threads — and do this holding the piece upside down so no alcohol runs down into the internals of the device.

Keeping the coil healthy

The inside of your heater cup should stay white. If it’s turning black, it’s being run too hot or too dry — running your concentrate down to nothing, not loading enough, or not watching the device during a session. The fix is to pay attention and stop the session early when the material runs low instead of letting it cook dry.

Burn-off cleaning — bringing a charred cup back to white

If the heater cup has already gone black, a burn-off cleaning is the only way to get it back to its original white. The best part: it uses the coil’s own heat, so there’s no torch involved.

What you’ll need:

• A cub — a small attachment that connects your coil to an e-cig mod.
• A mod capable of 40 watts. You won’t actually run it at 40 — there’s just no such thing as a “38W mod,” so you need one that reaches 40 and dial it down. (The Core itself can’t do this — it’s a single cell — so you need a variable mod.)

The burn-off:

1. Connect the coil to your mod through the cub.
2. Set it to 38 watts. Don’t go over — 40 will crack the cup, and 35 won’t get hot enough to clean it. 38 is the sweet spot.
3. Hold the mod and coil upside down and run it for 2 minutes. Upside down matters: it loosens all the reclaim and lets it fall back down onto the heater so it burns off — including the gunk baked into the cracks and the screw holes.
4. Let the device cool completely.
5. Repeat for another 2 minutes if it needs it.

Stop when no more vapor is coming off the coil and the heater cup is back to its original white. That’s how you know it’s done.

Once it’s white again and reading right around .44 ohm, set it and forget it — leave the screws alone so the lead wires stay put.
