I have a candle in a nice jar. How do I get the left over wax out of the jar.?

put it in the microwave for a couple of seconds at a time, say 20 seconds and have like a paper cup or something handy to pour the melting wax into. Once you get all the wax out, wash the jar in very hot water aand it should be clean.

You can remove the wax by heating the jar and all in a very low oven. When the wax is all melted, pour it out and wipe the excess wax out of the jar with paper towels while the jar is still warm.

Put the jar in the freezer. The wax will freeze and comes off the jar easily.

You can put the jar in the freezer and try to pick it out, or boil a pot of water and put the jar in the hot water-be careful with that in case the jar cracks.

Boil some water (hot tap water will work too) let it sit for 15 min or so and with your fingers or a butter knife scrape whats left. You may have to add more hot water if you don't get all the wax out the 1st time.

Cheers!

boiling water it may take a few times depending on how much wax is in the jar boil the water pour it in leave it for a few seconds stir the lose wax a few times pour it out and repeat

Run it under warm water and then let it soak. After about 30 minutes to an hour you should be able to get it off easier. Make sure it's WARM.

soak it in water just warm enough to soften the wax where you can the spoon it out

Stick it in the freezer. When it's frozen it will chip out easily.

freeze about 15 minutes and chip out with butter knife
