What matierials does melted candle wax not stick to

Paraffin burns quickly without a trace, while a wax product melts slowly, practically without dripping and sometimes making crackling sounds.
Beeswax pillar candles have a light honey aroma, while paraffin is odorless.
The wax is cut easily and effortlessly, the cut is smooth and does not crumble. Paraffin is a solid material, and from such an effect it simply crumbles.
If you do not use a wax candle for a long time, it becomes covered with a white coating. At the same time, paraffin, at any time and storage conditions, externally remains unchanged.
If you hold the glass over a paraffin candle flame, noticeable soot will immediately form on it. The wax either does not give off soot, or it can only lead to a subtle darkening of the glass.

Around the battery housing, on the bottom, you might be able to scrape a bit of the wax off. Melt the wax on a piece of aluminum foil. Depending on the length of the crack, use the melted wax and just dab around with your finger. Don't burn yourself. It'll be the same color and shade and should blend in with your current candle. Hope that works for you.

Candle wax usually melts around 130F, water boils at 212F. Heat the water to 150 or so and the wax will melt, since its lighter than water it floats to the surface, and away from your garment. Let cool, remove wax. Try to make sure the garment stay at the bottom, small weight etc. If the water temp of you hot water is set at 140 you may get away with just letting it sit in that for a while.

Turn the bowl upside down and use a match or much better, a cigarette lighter to melt the wax directly below (normally above) the black wick, moving the flame it back and forward. Watch out for hot wax dripping onto your skin!
Then turn the bown over and use a butter knife to scrape the wax above the wick away and remove the wax above and on either side of the wick. You may have to do this operation a few times, but eventually you should be able to gently get the knife under the buried wick and (gently!) prise it back into an upright position.
Don't do this roughly, or you could snap the wick off at its base, it needs to be pretty much out of the wax and softened by the flame before you try to bend it back up.

Then light the cantle and let it burn for ten minutes, until the wax all around it is clear liquid - then blow it out, and after ensuring that the wick tip is no longer glowing, quickly crush a few absorbent paper towels into the bowl and upturn it again. The aim is to allow the towel to absorb excess molten wax, which should preven the wick from being buried under wax again when the candle cools.

try hot air from hair dryer. As soon as wax melts, be ready to clean immediately.

No! you should not use the candle as a moisturizer when it melts unless it's a soy wax candle. Most candles are made from paraffin and it's really not meant for the skin.

Sure, that's the great thing about flameless candles - they are weather proof as the wind won't blow the candle out. But be careful in extremely hot temperatures as the heat could melt the actual wax of the candle.

heater core most likely is the smell kinda sweet at all ?
