Home Fragrances

Candles, reed sticks and the units that plug in:

the real split is between scent you burn, scent that evaporates on its own and scent a machine pushes into the room. A jar candle throws its fragrance once the wax has melted to the edge, and soy or coconut blends burn slower than plain paraffin; holders and lanterns sit with lighting. A reed diffuser needs no flame and no power: rattan sticks draw oil from the bottle and scent a bathroom or closet for weeks, though never a big living room. Linen sprays land on curtains and cushions as often as in the air. An ultrasonic diffuser shakes water and a few drops of oil into a cool mist and suits a bedroom or an office. Plug-ins and automatic sprayers from Glade and Air Wick are the cheapest units to buy and the dearest to run, since each takes only its own brand’s refill. At the top sit nebulising machines that run pure oil with no water, some wired into the air-conditioning, the kind hotel lobbies, clinics and shops use.

Diffuser oils, refills and the 120-volt plug:

an ultrasonic diffuser wants thin oils or water-based fragrance. Thick resins and vanilla-heavy blends gum up the vibrating disc. Costa Rica runs on 120 volts with the same flat-pin plugs as the United States, so a diffuser or plug-in bought there works here without an adapter. The catch is the refill: a plug-in or automatic sprayer is only as good as the refills on local shelves, and one whose refills are not sold here has to be fed by courier.

What a lit candle or a used diffuser is worth:

usually not much, because new ones are cheap. Supermarket candles and aerosols cost under ₡5,000 and a basic ultrasonic diffuser starts around ₡6,500, so a used basic unit has to be close to new to save anyone money. Imported three-wick jars from brands like Yankee Candle cost several times a supermarket candle, so an unlit one keeps much of its value, and a designer diffuser or commercial scent machine is a fair used buy once you have seen it run. A lit candle, an opened aerosol or a half-empty reed bottle has little resale left: the scent has started to go.

Scale on the ceramic disc, tunnels in the wax:

most used diffusers that fail have a mineral crust on the small disc at the bottom of the tank, the part that makes the mist. One that hums or bubbles without misting has usually had tap water left standing in it, so ask to see it run, and look for a cloudy or crazed tank that points to strong oils. Check the adapter comes with it. On an automatic sprayer, open the battery door: green corrosion from a leaked battery ruins the contacts. Candles show their history on top. A hole burned down the middle with a wall of wax around it is tunnelling, left by short burns, and that wall will never melt. Reeds that soaked in one oil carry it into the next, so plan on fresh sticks.

Listing an unlit candle or a shop’s scent machine:

copy the scent name exactly as it reads on the label, because buyers search for the fragrance they already know, and say whether the candle has been lit. For anything electric, a short video of it misting settles the main doubt; name the refill or cartridge it takes and how many spares go with it. When an office in Alajuela or a shop that is closing sells its scent machine, list the leftover oil with it and say whether it ran on its own or through the air-conditioning. Anyone driving in from Cartago for a diffuser will want to watch it mist before paying, so have it filled, plugged in and boxed with its adapter when they arrive.
