Put a lantern away in October and it can look perfectly fine until the evening you want it again in February. That is when the rust shows up inside the fount, the wick splinters between your fingers, and the canister you forgot about has left a sticky ring on the shelf. Most winter storage damage is self-inflicted, and nearly all of it is avoidable with half an hour of work now rather than a replacement later.
Leaving Fuel in the Tank or Canister
Paraffin, lamp oil, citronella and butane all behave badly when left sitting for months. Fuel slowly degrades, turns gummy and varnishes the inside of a fount, and the residue is far harder to shift than fresh fuel ever is. Brass and steel corrode from within, rubber seals and washers dry out and shrink, and a part-used gas cartridge can quietly leak its way through the winter.
Deal with the fuel before you deal with anything else:
- Run the lantern dry outdoors if you can do it safely and the weather allows, rather than tipping fuel back into your main container. A little contaminated fuel spoils the whole can.
- If you must drain a fount, use a funnel into a clearly labelled, purpose-made metal container. Never a drinks bottle, never a jam jar, and never indoors.
- Wipe the inside with a dry cloth and leave the filler cap off for a day so any vapour can escape.
- Disconnect gas canisters, check the seals, and store them upright somewhere cool and ventilated, well away from boilers, heaters and anything with a pilot light.
Where the maker's instructions say nothing about storage, a dry fount is the safer default. Some lamps are happy with a small quantity of paraffin left in them; if yours is one of those, the manual will say so. Never pour fuel down a drain or into a bin.
Damp Sheds, Cold Garages and Condensation
The classic mistake is treating the shed as a free storeroom. A timber shed that swings between frosty nights and mild, wet days is one of the worst places for a lantern. Condensation forms on cold metal, wicks draw in moisture and go mouldy, electrical contacts fur up with green corrosion, and painted finishes blister.
Look for somewhere dry and reasonably stable instead: the back of a wardrobe, a spare-room cupboard, a dry loft that does not bake in summer, or a shelf in a heated utility room. Avoid greenhouses, unheated conservatories and cellars. A few silica gel sachets tucked into a cloth bag will help, and a monthly look-over costs you five minutes.
Why a Sealed Plastic Bag Can Backfire
Wrapping a lantern in a sealed polythene bag feels protective, but it traps whatever moisture is already in the air around the metal. When the temperature drops, that moisture condenses on the coldest surface, which is usually your lantern. A breathable cotton pillowcase or an old tea towel is better. If you do use plastic, make sure the lantern is bone dry first and add a silica sachet.
Crushing Wicks and Bending Burners
A wick left in a burner for six months takes on the shape of its tube, frays at the edges and refuses to feed properly. A lantern stuffed burner-down into a box will bend its gallery, and glass globes stacked against each other chip at the rim.
Before storage, trim the charred end with sharp scissors, then lift the wick out and store it flat in a paper envelope. Keep spare wicks flat too, in a book or a shallow tin, rather than bundled with elastic bands. Wrap the lantern in cloth and stand it upright with nothing resting on top of it. Remove glass globes, wrap each one in newspaper and keep them in a single padded layer.
Mantles deserve special care, because they are fragile even when new. Do not touch them, do not let the lantern lie on its side, and do not pack anything against the burner. Stored upright and undisturbed, a mantle will often survive the winter intact.
Leaving Batteries in Place
Every winter, a good number of LED lanterns are ruined by cells left inside them. Alkaline batteries leak as they age, and the residue eats through contacts and springs. Even when they do not leak, they will be flat by spring and may have corroded the terminals just enough to make the lantern unreliable.
Take the batteries out, store them in a dry tin away from loose metal objects, and note which way round they sat so you are not guessing later. For rechargeable lanterns, charge them fully before storage and top them up every couple of months rather than leaving them flat for the season. If you find light white or green powder on the contacts, clean it off carefully with a dry cloth before fitting new cells.
Piling Lanterns Together Without Padding
A crate of lanterns rattling against each other over winter is a crate of scratched enamel, chipped glass and bent handles. Cast-iron and steel lanterns are heavy, so anything stored beneath them will lose the argument.
Store lanterns in a single layer, upright, with a piece of cloth or card between each one. Keep the heaviest at the bottom of a shelf rather than in a box on top of lighter items. Do not hang a lantern from its handle on a nail for months on end; the weight stresses the handle joint and the solder where it meets the body. If a lantern has a hook or bail that folds, fold it down and let the base take the weight.
Forgetting to Label and Check Anything
By March, most people cannot remember which lantern needed a new wick or which one is missing its glass. A strip of masking tape on the lantern, or a card dropped into the box, solves that in seconds: note the wick size, the fault, and the fuel type it takes.
Keep a small spares tin with wicks, a washer or two, a spare mantle and a soft brush. Then check everything once a month. Pick each lantern up, look at the burner and the fount, and deal with rust the moment you spot it rather than in spring, when it has had months to spread.
A Simple Winter Storage Routine
If you would rather work from a checklist, this order covers almost every lantern type:
- Empty, drain or burn off the fuel, and store it safely and separately.
- Disconnect gas canisters and check their seals.
- Trim or remove the wick and store it flat.
- Remove batteries and store them elsewhere.
- Clean soot and dirt from the burner, glass and fount while it is still easy to shift.
- Remove glass globes and wrap them individually.
- Wrap each lantern in cloth and stand it upright, in one layer, somewhere dry.
- Label anything that needs attention, and give the whole collection a quick monthly look.
None of this takes long, and it is far pleasanter than scraping rust off a burner on a cold evening when you actually wanted some light. Treat your lanterns well through the wet months and they will reward you with a clean, steady flame the first time you reach for them again.
