Frequently asked questions

Do you have a question?

We’d be happy to answer it.

Below, we’ve listed the most frequently-asked questions from our customers. Is your question not on the list? Then please don’t hesitate to contact us.



It’s very important to use our candles properly so that you can get the most out of them. For example, did you know that you should always place our rustic candles at least 10 centimeters from each other to prevent them from leaking? 

How do I remove wax stains from the table, furniture or textiles?

First remove any loose pieces of wax by hand. Then lay a sheet of kitchen paper on the remainder of the wax stain and run over it with a hot iron. The candle wax will stick to the kitchen paper.  If the stains are on a smooth surface, a hair-drier is an effective way of melting the candle wax. You can then remove it with kitchen paper.

What do I need to bear in mind when I want to burn several candles alongside each other?

It is important to make sure there is a sufficiently large distance between the candles (at least 10 cm). Always burn the candles in a suitable holder or on a fire-resistant coaster.

Must the label on the bottom of the rustic candle be removed before lighting the candle?

No, the so-called bottom label of the candle does not need to be removed.

Must the label around the rustic candle be removed before lighting the candle?

Yes, the label should be removed before using the candle.

Do I have to use all fragrance sticks at the same time?

The strength of the fragrance is made for the eight sticks. If the fragrance is too strong for you, you can always use less sticks. This way the fragrance will be less intense.

Must I rotate the fragrance sticks every day in order to distribute the scent properly?

It is not necessary to rotate the sticks. The quality of the sticks in our reed diffusers is so good that they distribute a lovely scent in your home for several weeks.

Can I heat my house using candles?

Online you can find various suggestions using ceramic flower pots and tealights to heat a room. We don’t recommend this as a way to heat your home due to safety reasons associated with burning candles. For safety reasons we always advise to use a minimal distance of 10 centimeters between the candles and to use proper candle holders. Also it’s very important to never leave the candles unattended.

Can I paint your candles?

Yes, that is possible. We advise to use special candle paint. It’s even possible to draw on a candle with a blunt pencil as long as you don’t scratch too deep. You can also paint the outside of our fragranced glasses or tealight holders with regular hobby paint.

Can I put a personalized label made from paper around the candle?

Yes you can. Keep in mind it’s important to remove the label before you light the candle. If you have customized a glass candle; be sure that there is no over hanging paper that can in contact with the flame.


Here you can find some answers about recycling our products

Can glass candles be thrown in the recycling bin without being cleaned?

Yes, they can. The industrial glass recycling process will separate this material. Only the CleanLight glass can't go to the glass waste bin as it's made from borosilicate glass.

How can I remove wax from a glass to be able to re-use it?

The simplest solution is to place the glass in the oven at 70 degrees Celsius. ( Ensure you wear protection when removing the glass from the oven ) This should melt all the residual wax and enable you to throw it away or reuse it. Once empty you can further clean with some paper towel once the wax is removed.

You could remove it also with hot water, but be sure to not get the wax in the drain. Dispose of the waste wax in your household waste.

How do I best dispose of left over wax?

You can put it in the waste bin or reuse. You can also check if there’s a community looking for left over wax to make new candles of it.

How do I dispose of reed diffuser liquid?

This is officially chemical waste so you can't pur it in the sink. If you don’t enjoy the fragrance perhaps first check with your neighbors and see if they would like the product or move it to another area of your house. Alternatively we’d recommend to put the diffuser in the shed/ outhouse and let it stay there until the liquid is completely evaporated.

Can the wooden sticks form my reed diffuser go into the ‘green waste’?

No, the wooden sticks absorb solvents from the liquid in your reed diffuser; these are not OK for the environment and should not be added to the green waste for recycling. You can instead put them in the regular waste bin.

Can I put glasses with wax residue in the dishwasher?

Due to the melting point of wax this is not recommended as your drain may get blocked when the wax cools down.  Heating this up in the oven or rinsing with hot water in the sink are still the recommended options.

Are plastic candle containers recyclable?

Yes, they are. In the Netherlands you can put them in the PMD/ PBP bags along with other plastic recycling.

How do I recycle my aluminum tealights?

In the Netherlands you can put them in the PMD/ PBP bags along with other plastic recycling. In other countries please check with your local recycling procedures.

Is it harmful to re-use wax?

As long as you don’t use outdoor wax indoors and don’t see visual soot (black smoke) coming off the wick it’s OK. If you make your own candle(s) be sure to use the right kind of wick; hobby shops can help you with this.

Safety is a top priority for us. That is why all our candles display symbols that explain how to use the candle correctly. 

Which are the most suitable candleholders/tealight holders for burning candles and tealights?

It is very important that the holders are manufactured from non-flammable materials and that there is a sufficiently large distance (at least 10 cm) between the candles. For a tealight holder, it is important that the heat generated by the burning tea-warmer can escape. The holder should therefore not be closed.

Our accessories have been carefully designed to allow our candles to burn optimally and to comply with all safety regulations. Our accessories are available in different types, shapes and materials. You can view them here.

Why are memorial lights only suitable for burning outside?

Our memorial lights are intended to be lit once so that they can then burn continuously. Because it is not possible to keep watching the candle all the time, the chance of fire and its consequences is reduced considerably when the candle is burned outside. Always make sure that you do not place the candle in the immediate surroundings of flammable materials.

Should I put out candles when I leave the room?

Yes, a burning candle may never be left unattended. Candles burn with a naked flame so there must always be somebody nearby.

What is the best way to put out a candle?

The best way to put out our candles is with a candle snuffer, which you should hold over the wick as far as the liquid wax. The wick then stops burning without an afterglow, it doesn’t break off and it is covered with new candle wax for the next time you light the candle.

Never put out a candle with water!

Are candles containing paraffin harmful for your health?

When you buy candles, always make sure they’ve got the RAL quality mark on it. This means the candles don’t soot and that the raw materials are checked, so they don’t contain benzene or toluene. When candles have the RAL quality mark, you don’t have to worry about harmful ingredients. Read more about the RAL quality mark here.


Find answers to your CleanLight questions here.

Can I put the holder in the dishwasher?

We don’t advise to use the dishwasher to clean the holder, but to clean it carefully by hand. If you put the holder in the dishwasher, the print might fade after a while. It’s also possible water will enter the double walled glass.

How do I clean the holder?

There will be no wax remains as the refill burns up completely. If you do want to clean the holder, it’s best to use a kitchen towel or the soft side of a sponge. You can add a small bit of warm water and soap. Don’t forget to remove the wick plate before cleaning the glass. We advise to remove it with a wooden or plastic spoon. Don’t use a metal object, this can damage the glass. The wick plate can go to the waste bin. Make sure the holder is dry again before you use it again.

Are there also holders in different colours?

At this moment there’s only the green holder. Consumer tests show the green glass was most appreciated. In the future it’s possible we introduce different colours.

Is there also a starter pack with a different fragrance?

At this moment we only have the starter pack with this fragrance. It’s always possible that we’ll have a different fragrance in the starter pack in the future. If you don’t like Gardenia & Fig, you might like one of our other CleanLight fragrances.

My holder broke. Can I recycle it with other glass waste?

No, the holder is made from borosilicate glass, a special handmade glass that's suitable for high temperatures and the will last for a long time. In case your holder breaks, you can’t recycle it with other glass waste. It’s better to put it in the regular waste bin. Be careful for sharp edges!
