Shine On: The Simple Steps to Cleaning Your Candle Containers
By Karen Platt, Co-Founder, CandleXchange
When your candle has burned down, it's tempting to feel like the job is done. But there's one more step — and it's a satisfying one. Cleaning your candle container properly means the glass can go around again, whether that's through our Return & Swap program, as a repurposed vessel in your own home, or on to someone who needs it through our UpCandle program. (And if you want to make sure you get the most from your candle before it reaches this point, our guide on why the first burn sets the tone for your candle is worth a read.)
Here's everything you need to know about cleaning a soy candle container, including three reliable methods and some tips for getting a streak-free result.
Before You Start: Two Things to Know
Leave a Little Wax in the Container
The easiest time to clean a candle container is when there's still about 1cm of wax left at the bottom. This small amount of residual wax makes it much easier to remove cleanly in one go, rather than picking at a thin smear of wax stuck directly to the glass. If you've burned your candle right to the end, the methods below will still work — they just take a little more effort.
Let the Candle Cool Completely First
Always wait until the wax is fully solid and the container has returned to room temperature before you start cleaning. Trying to remove warm or soft wax makes a messier job — and handling hot glass is never a good idea. Give it at least an hour after the last burn before you begin.
Three Methods for Cleaning Your Candle Container
Method 1: The Freezer (Our Favourite)
This is the method we recommend most — it's clean, simple, and works beautifully on soy wax because soy shrinks slightly as it freezes, pulling away from the glass edges.
- Place your container in the freezer for approximately 20 minutes.
- Remove the container and use a butter knife or spoon to gently pop the wax disc out. It should come away cleanly, often in one piece, including the wick.
- Dispose of the wax in the bin — not down the drain.
- Remove any remaining residue with a paper towel.
- Wash the container with hot soapy water, or run it through the dishwasher.
The freezer method is particularly satisfying because there's very little mess and you're left with a clean, clear container in under half an hour.
Method 2: Boiling Water
This method uses heat rather than cold to separate the wax from the glass. It takes a little longer but is very effective, especially if the wax has set very hard or you've missed the residual wax window.
- Exercise caution and pour boiling water into the container, leaving a few centimetres of space at the top.
- As the water cools, the wax will float to the surface and solidify.
- Once the water has completely cooled, lift out the wax disc and dispose of it in the bin — not down the drain.
- Remove any remaining wax with a paper towel.
- Wash the container with hot soapy water or in your dishwasher.
You may need to repeat this method once or twice if there's a thick layer of wax or if residue remains on the glass sides.
Method 3: Hot Water Soak
If you'd prefer to avoid boiling water, a hot water soak achieves a similar result with a little more time.
- Sit your candle container in a bowl or sink of hot (not boiling) water, so the waterline sits below the rim of the container.
- Leave it for 10–15 minutes until the wax has softened.
- Hold the container steady with one hand and use a butter knife to loosen the wax and wick base.
- Dispose of the wax in the bin — not down the drain.
- Remove any remaining residue with a paper towel.
- Wash with hot soapy water or in the dishwasher.
Tips for a Streak-Free Finish
Soy wax has a slightly oily residue that can leave smudges on the glass if you go straight to rinsing. A quick wipe with a paper towel before washing makes a significant difference. After washing, buff the glass dry with a clean cloth rather than leaving it to air dry — this avoids water spots.
For stubborn labels or adhesive residue on the outside of the container, a little coconut oil applied with a cloth will lift it cleanly without scratching the glass.
What to Do With Your Cleaned Container
Return It Through Return & Swap
The best thing you can do with a cleaned CandleXchange container is return it to us. Our Return & Swap program means your container gets cleaned, inspected, refilled, and sold again — keeping it out of landfill indefinitely. In exchange, you receive 30% off your next candle order, and free return shipping is included.
It's worth knowing that candle containers are made from tempered glass, which cannot be processed by kerbside recycling in Australia. There is currently no recycling infrastructure in this country capable of handling tempered glass. That means if your clean container goes into the recycling bin, it will still end up in landfill. Return & Swap is the only genuinely circular option. If you're curious about why we use the specific glass and wax formulation we do, our post on the soy wax debate covers the thinking behind our material choices.
Repurpose It at Home
A clean candle container makes a beautiful and practical vessel for pens, brushes, cotton rounds, small succulents, or tea light candles. The thick, quality glass of a CandleXchange container tends to look right in any room — which is part of why we designed it to last.
Frequently Asked Questions
Can I put my candle container in the dishwasher?
Yes — once the bulk of the wax has been removed using one of the methods above, CandleXchange glass containers are dishwasher safe. Remove as much wax as possible first, as melted wax residue can coat the dishwasher interior and trap in the filter. A quick paper towel wipe before loading makes the wash cycle far more effective.
Can I pour melted candle wax down the drain?
No — this is one to avoid regardless of the wax type. Soy wax solidifies as it cools and can build up in pipes over time, causing blockages. Dispose of all wax in the bin, whether it's solid, semi-solid, or melted.
Can I recycle my candle container?
Unfortunately, no. Candle containers are made from tempered glass, which has a different melting point from standard glass and cannot be processed by Australian kerbside recycling. Putting tempered glass in your recycling bin can contaminate the entire load. The best option is to return it through our Return & Swap program — or repurpose it at home.
What if I have containers from other candle brands?
Used containers from other candle brands can be donated to our UpCandle program. We collect them, clean and refill them, and donate them to domestic violence survivors across Australia who are rebuilding their lives in new homes. Get in touch to find out how to contribute.
