How to Melt Leftover Candle Wax

Introduction

Candle wax is paraffin, which means that it is a kind of plastic. While it might not look like it when you are burning the candles, paraffin can be melted down and re-used to create new candles. The only downside is that candle wax needs to cool completely before you attempt to use it in other projects. 

How to Melt Leftover Candle Wax

Candle wax is usually a combination of paraffin, soot (from the wick), stearic acid, and scent. Different companies sell candles that are made from different combinations of these ingredients. The best candle to use in this scenario is vegetable-based wax, which has no petroleum products.

This means that you can melt it down and use it again without any negative health effects or concerns about toxins leaching into your food. If you have leftover non-vegetable-based candle wax, it should be destroyed rather than melted down for other uses. In this article, I will discuss how to melt leftover candle wax.

Step-wise Guide on How to Melt Leftover Candle Wax

  • Using a sharp knife, cut leftover candles into small pieces. This is to make them easier to meltdown and helps in the melting process itself.

  • In a deep pan, over medium heat, add ½ cup of water, ½ tbsp vegetable oil (if you want a better end product), and put your cut candle pieces and let it cook until they just melt down completely. Stir now and then so that it doesn’t clump up or burn on the bottom. It should take about 4-5 minutes for the wax to start melting after you’ve put the ingredients together in your pan. You can reduce or increase time depending on how quickly you want to finish this job! Think like when we’re trying to boil an egg.
  • Once the wax has melted down and got mixed up completely with the oil/ water mixture, and you can switch off your stove or turn it to low heat and then let this mixture cool down for a little while. About 10 minutes will do.
  • After cooling down a bit, strain out all the wax pieces (they’ll be brittle) from the leftover liquid in your pan by pouring it through a coffee filter or cheesecloth. You don’t have to throw away these wax bits & crumbs, though! They still have their uses: candles, potpourri, etc.  And if you want to keep them longer than that like me, put them in an airtight container or plastic bag and stick them in the freezer. They won’t melt there.
  • Finally, you can store your liquid wax (if any) in a clean container and use it as you please! For example: if your leftover candle has been holding up amazing even when lit, then use the residue to make embeds for your next poured candles! If not, I’d say to chuck that liquid away or maybe keep it as an emergency kind of thing!

Precautions While Performing How to Melt Leftover Candle Wax

While melting leftover candle wax, there are a few precautions that you should take for your own safety. First, always use gloves while handling the melted wax since it may cause skin irritation or other allergies.

If you have any cuts on your hands, avoid them at all costs and protect yourself with gloves as a precautionary measure against possible injuries. This is also recommended when using sharp metal tools to remove the wick from the candle holder since this metal may poke your fingers if not given proper protection from thin rubber gloves.

When working around the fire, use complete protective clothing such as a fire-resistant coat and pants. Finally, don’t overheat wax to melt it faster than required because overheating causes the release of small air bubbles, which would contaminate the final product (wax).

Use Complete Protective Clothing Such as a Fire-resistant Coat

Black or dark wax resulting from burning a candle for too long can affect the quality of the wax that you are trying to recover, even though it may not be obvious. To prevent this phenomenon, always let your candles burn until they produce yellow-colored flame and then put them off.

This way, you will save a lot of time in the melting process because otherwise, spent solid black wax will need to be disposed of separately before it could be collected for recycling purposes.

Nowadays, many people like to do candle making as a hobby where they make dozens or hundreds of candles at one go to avoid wastage by disposing of these wax holders off after they have served their purpose.

What Can You Do With Leftover Candle Wax?

You buy a candle, and you burn it. Then, it’s gone. So what do you do with the leftover wax? Well, here are some ideas to consider:

It makes an excellent lubricant for sliding doors and windows that have become stuck or creaky. Rub the wax into the track; open/close the door to let any excess drip off before putting the door back in place. This works great on double-hung wood windows! Add some essential oils (optional) as desired.

Place small amounts of leftover wax chunks into clean glass jars, seal them tightly, and use them as scented votive candles – this is a great way to reuse those tiny containers from trick or treat candy! Melt old candle stubs into a clean glass bowl, and dip your old egg-shaped ornaments into the melted wax to give them a new finish.

Dip pinecones, seashells, and other natural items in leftover wax to give them a candlelit glow. Meltdown your candle stubs – this works best if you use stubs from a white or cream-colored wax (colored wax has a lower melting point than clear).

It’s best to melt up several at one time, so you have more wax than you need for any of these projects. The excess melted wax can be stored in glass jars until the next use! Enjoy becoming creatively green!

How to Melt Candle Wax in A Microwave?

  • Press the wax into a container.
  • Put three tablespoons of water (or less, depending on how much you’re melting) in a glass Pyrex measuring cup and heat it in the microwave for 30 seconds. Add one or two drops of dish soap and stir with a spoon to help remove any grime that might be stuck to the bottom of your container.
  • Make sure there’s enough room at the top for the melted wax so you can pour off any excess water once it cools down. If not, use another microwave-safe bowl or cup as long as they fit inside each other snugly without touching each other when stacked together.
  • Place both containers carefully inside the larger bowl along with all your scraps of wax, and place in in the microwave.
  • The water will begin to bubble and steam as the wax starts melting down into a puddle. Keep an eye on it since you don’t want it to overflow while the wax is still hot! (It’ll be difficult to clean if that happens.) You may need to remove some of the water with a spoon or a paper towel, so there’s room for your wax container inside. Alternatively, you can use something like an egg cup instead of two containers to give yourself extra room.  
  • Remove everything from the microwave when most of your scraps of the leftover candle have melted out into one big pool (it may still look splotchy at first until all the bits melt into each other.)
  • To remove any excess water, use a spoon to carefully skim off the top layer of water that forms on top when you first take it out and let it cool down for a few minutes.
  • When most of your wax has melted into one big puddle, pour the remaining bits and pieces into your container so that you can reuse the leftover candle wax again.  You may need to reheat your wax once more to get rid of any remaining chunks before placing them in your tin or jar.

How to Reuse a Candle With No Wick?

Candles are beautiful and stylish. Why throw them away when they burn out? With a little know-how, you can reuse that candle without the wick.

  • Never put a hot candle in cold water as it may break or crack. Only move the candle if it is burning down slowly, and you want to save the majority of wax for another use.
  • Many people think that saving melted wax means putting leftover burning candles into an old coffee can of water on their stovetop and letting it melt overnight–don’t do this! This could result in burns or fire; never let a candle burn unattended!
  • Get rid of any residue like wick material, fluff, or charred wax that remains in the candle after use. This debris can cause a fire if you are not careful.
  • Keep children and pets away from candles; they love to play with them!
  • Make sure your candle is completely cooled before storing leftover melted wax in an air-tight container. Some people choose to store it in an old pot/pan that they don’t mind ruining because it may get a few scratches on it; this will not harm your finished product, but I like my pots clean and shiny, so I chose to use a new Pyrex baking dish instead (I really needed one anyway). You can also use any glass jar or Tupperware of your preference. Then place the glass container in a cool, dry area, like a cupboard or pantry–do not store candle wax near your stove!
