Safely Removing the Silicon Stopper from a Lost Mary BM600
The Lost Mary BM600 is one of the most recognisable compact pod vapes on the Australian market, and plenty of users eventually want to peek under the hood once the factory fill runs low. The little black or translucent plug sitting in the fill port is a small silicon stopper, and it is the part most people damage first when they try to remove it without a plan. A torn stopper leads to leaks, a drop in flavour, and a pod that no longer feels sanitary to use.
Many vapers in Sydney, Melbourne and Brisbane treat their BM600 like a sealed unit and only discover the silicon piece when a refill tutorial appears on social media. Others find it while troubleshooting a dry hit or a gurgling sound. Either way, the plug is meant to be removed, cleaned and replaced, not ripped out with a fingernail or a kitchen knife. Treating it gently keeps the device working the way the engineers intended.
This walkthrough covers the tools, the technique and the small habits that prevent the stopper from stretching or snapping. It also flags a few Australian-specific points, from the way heat in a Perth summer softens the silicon to the way locally stocked products from the Lost Mary Pro catalogue are built for repeated top-ups rather than single use.
Why the BM600 Has a Silicon Stopper in the First Place
The silicon stopper on a BM600 sits inside a small oval opening near the base of the device, just below the mouthpiece. Its job is to seal the internal pod against air, dust and the gradual evaporation of e-liquid. Without it, the cotton wick dries out quickly and the flavour profile collapses long before the battery is flat.
Because the BM600 is a sealed pod system rather than a true disposable, the stopper also gives the device a second life. Refillable BM600 variants and compatible pod replacements rely on that little plug holding pressure during a top-up. Once the silicon stretches or splits, the seal is compromised and even the smoothest throat hit starts to taste faintly of plastic or leaked juice.
Australian users also have to factor in the prescription-only nicotine rules managed by the TGA. Devices that can be refilled cleanly with the original stopper intact are easier to keep in rotation without buying a new unit every few days, which suits anyone trying to manage cost in a market where nicotine liquids carry a noticeable premium over the standard 30 mL shortfill bottles sold at most Australian vape retailers.
Gathering the Right Tools for a Clean Removal
You do not need a workshop to lift a silicon stopper, but a few everyday items make the job safer. The goal is to apply a flat, even force rather than digging into the rubber with a sharp point.
What to have on hand
- A small flat-head screwdriver or a plastic spudger from a phone repair kit
- Rounded-tip tweezers for guiding the rubber once it starts to lift
- A clean microfibre cloth or lint-free wipe
- Optional: a SIM ejector pin or a folded guitar pick for tight corners
Avoid paperclips, sewing needles and craft knives. The metal is too thin to spread the load across the stopper, and the moment it slips it will cut the silicon or score the plastic housing around the fill port. Both outcomes turn a thirty-second job into a warranty issue, particularly on the BM600S and BM6000 ranges where the housing is a little tighter than the standard model.
Setting Up in an Australian Home Environment
A stable surface matters more than people think. Kitchen benches, dining tables and the fold-out tray on a home office desk all work well, but make sure the device is sitting on something non-slip so it does not skid when pressure is applied. A folded tea towel is a quick fix for a glossy benchtop in a Brisbane apartment.
Climate plays a quiet role too. In a hot Darwin or Perth summer, the silicon inside the BM600 softens slightly and the plug can feel almost sticky. A few minutes in a cooler room helps the rubber firm up, which actually makes removal easier and reduces the risk of stretching. By contrast, a device left in a car overnight on a winter morning in Hobart will have a stiffer, more brittle plug that benefits from a minute of warmth from your hands before you start.
It is also worth noting that Australian e-liquid bottles often have narrow drip tips. Have a paper towel or two ready, because a small amount of residual juice tends to surface the moment the seal breaks. Wipe it before it drips onto the device shell or your work surface, and keep the bottle capped until you are ready to refill.
Gentle Techniques for Lifting the Stopper
Start by holding the BM600 firmly in one hand, with your thumb pressed against the body just above the LED indicator. This gives you a stable anchor point and stops the unit from rolling as you work on the base.
Slide the flat edge of your chosen tool under one corner of the silicon stopper, no more than a couple of millimetres deep. A slow, gentle twist of the wrist is enough to pop that corner up. Move to the opposite corner and repeat, working the plug loose in a rocking motion rather than prying it straight out. The silicon will deform slightly, then release without leaving a mark on the rubber or the surrounding plastic.
If the plug refuses to budge, stop. Forcing it at this stage almost always tears the rim, particularly on older devices that have been sitting in a hot car or a sunny windowsill. A few extra seconds of patience, a fresh grip, or warming the rubber with your fingers will usually solve the problem without damage and save you the cost of a replacement pod.
Common Mistakes That Tear or Stretch the Seal
The fastest way to ruin a BM600 stopper is to grab it with fingernails and pull. The rubber is softer than it looks, and once a small nick appears the tear travels quickly. Pliers are even worse, because they crush the stopper flat before ripping it out of the housing.
Habits that shorten the life of the seal
- Pulling the plug straight up in a single sharp motion
- Soaking the silicon in isopropyl alcohol to "soften" it
- Refilling through the mouthpiece instead of removing the stopper
- Reusing a stopper that has lost its original shape
A small amount of isopropyl alcohol is fine for cleaning the rim of the fill port, but it can swell the silicon and leave the plug permanently deformed if it pools around the rubber. Water has a similar effect if it seeps past the seal during the process, so keep liquids away from the opening until the stopper is fully removed and set aside on a clean tissue.
Cleaning the Fill Port Once the Plug Comes Free
With the silicon stopper resting safely on the cloth, take a moment to inspect the opening. A cotton bud lightly dampened with isopropyl alcohol will lift any residue from the rim without pushing it further inside. Rotate the bud rather than dragging it, so you do not leave fibres behind near the wick.
Look down into the port to check the level of the e-liquid. If the pod still carries a millimetre or two of juice, leave it alone. Topping up too early dilutes the flavour and shortens the life of the wick, which is one of the most common reasons a refillable BM600 starts to taste burnt within a day of being opened.
Once the port is clean and dry, place the stopper on a clean tissue while you prepare your refill bottle. A narrow syringe or unicorn bottle gives better control if you want to avoid overfilling, and the small increments help you stay under the two-millilitre capacity of the internal pod without guessing.
Putting Everything Back Together and Restoring the Seal
Refill slowly, pausing every few drops to let the wick absorb the liquid. Most BM600 pods hold around 2 mL, and a small syringe is the easiest way to stay under that line. Once the level looks right, give the device a minute to settle before you push the stopper home.
Align the silicon plug with the opening and press it down evenly with the pad of your thumb. You should feel a soft click as the rim seats inside the housing. Run a fingernail lightly around the edge to confirm there are no raised corners, then wipe the area with a dry microfibre cloth to remove any juice that escaped during the refill.
If the stopper no longer sits flush, or if it looks visibly stretched, replace it rather than forcing it back. Spare BM600 stoppers, replacement pods and full Tappo refill kits are stocked alongside the BM600 and BM600S ranges, so there is no need to retire the device over a small piece of rubber. If you are chasing the cleanest taste from your next refill, browse the smooth throat hit flavors guide and pick something that suits the way you usually vape, then keep a spare stopper in your drawer so the next refill is just as quick and clean as this one.
