How to use wax melts

1. Check the dish is empty and clean. Leftover spent wax dilutes whatever you add on top of it, which is the most common self-inflicted reason a fresh cube seems weak.
2. Break off the right number of cubes. One in a plug-in, two in a standard warmer, more only in a large one. Happy Wax publishes one to two shapes in an outlet or mini warmer, two to three in a standard warmer and five to eight in its largest - useful because it scales rather than giving one number for everything.
3. Put them in the dish and switch on. Not on the heating plate directly, and never on a bare bulb.
4. Wait fifteen to thirty minutes. A plate warmer is faster; a bulb warmer takes longer. If nothing has happened in half an hour, something is wrong - see warmer not working.
5. Change the wax when its stated hours are up, not when it looks different. It will never look different.

Three methods, best first.

The silicone dish method

If your warmer has a removable silicone dish, switch off and let it cool completely - properly cold, not warm. Flex the dish and the whole disc pops out in one piece. Ten seconds, no cloth, no waste.

The soften-and-lift method

For a fixed ceramic well. Run the warmer for one to two minutes so the wax is soft but not liquid, switch off, unplug, then lift the softened wax out with a paper towel. Wipe the well while it is still slightly warm.

The freezer method

For a removable dish that will not release. An hour in the freezer contracts the wax and it usually lifts out with a gentle press from underneath.

Never pour melted wax down a drain. It solidifies in the trap. And do not use a knife on a ceramic dish - a scratched well holds wax and gets harder to clean every time.

A common question and it deserves an honest answer rather than a workaround list.

The real answer is that you need a heat source held at a controlled temperature, and that is what a warmer is. The cheapest electric dish warmers cost very little, and anything improvised is worse on both safety and results.

What you can legitimately do without one: put a cube in a warm spot - a sunny windowsill, near a radiator - for a very faint passive release. That is essentially cold throw. It will scent a small enclosed space like a drawer, a wardrobe or a car, and it will not scent a room.

What we would not do: put wax melts in an oven, on a stove, on a radiator directly, in a mug of hot water, or over a tealight in improvised glassware. The first three are uncontrolled heat with no thermostat, the fourth just makes a mess, and the fifth reintroduces the flame you were avoiding.

Running spent wax for days, then concluding the melts or the warmer are no good.

The wax is a carrier. Fragrance oil evaporates out of it and the wax stays behind, melting and re-solidifying indefinitely, visually identical throughout. There is no point at which it looks used up, because it never gets used up.

Compounding it, your own nose is not a reliable instrument here: olfactory adaptation means you stop registering a constant background smell within minutes, so the room can smell perfectly good to a visitor and of nothing to you.

Practical rule: use the maker's stated hours as a timer. If they publish none - and most do not - assume roughly 8 to 12 hours per standard cube and change it then. Detail on why you cannot smell your wax melts.

• Do not overfill. More wax means a bigger mass to heat, a cooler pool and less fragrance. It is the opposite of what people expect.
• Do not add fragrance oil or water to the dish. Some listings suggest it. It is a warmer, not a diffuser, and neither belongs in there.
• Use a timer if you fall asleep near it. See warmers with a timer.
• Site it out of reach of animals. Liquid wax is hot, and spilled fragranced wax on fur gets groomed off and swallowed.
• Store unopened packs sealed and cool. Fragrance evaporates slowly from solid wax at room temperature. See storage and shelf life.
