Welcome to the fascinating world of wax melts! If you’ve ever wondered how long they last and how often you should change them, you’re in the right place. We are going to talk about why it’s important to change wax melts and give you some recommendations on how often to do so. So, how long do wax melts last?

Wax melts last for approximately 10-12 hours. This depends on the size of the wax melt, the temperature of the wax warmer and the quality of the materials used when the wax melt was made. However, if you have essential oils, you can keep adding to the wax.

You can keep adding essential oil to the wax for a while to help stretch out its usefulness of the wax, however, eventually, it will become very hard to clean up. Let’s take a closer look at this issue down below.

Factors That Determine How Long Wax Melts Last

Have you ever wondered how long wax melts can fill your space with their lovely scents? Well, a few factors can affect how long wax melts last. Let’s explore them!

Size of the wax melt

The size of the wax melt can determine its duration. Bigger wax melts usually last longer because they have more wax material. 

Alternatively, smaller wax melts might not last as long and can burn out quickly. Keep this in mind when choosing your wax melts.

Quality of the wax

The quality of the wax used in making wax melts affects how long they last. Higher-quality wax melts, like those made from natural waxes such as soy or beeswax, tend to burn for a longer time. 

They also have better fragrance-holding abilities. Cheaper wax melts might not last as long or have a strong scent. So, consider the quality of the wax when picking your wax melts.

Fragrance concentration

The concentration of fragrance oils in wax melts also impacts their duration. Wax melts with a higher fragrance concentration release a stronger scent but might burn out faster. 

On the other hand, wax melts with a lower fragrance concentration and can last longer but have a milder smell. Think about how strong you want your scent to be when choosing your wax melts.

Environmental factors

The environment in which you use wax melts can affect how long they last. Things like room temperature, airflow, and where you place the wax melt warmer can all make a difference. 

If it’s warm or there’s good air circulation, the wax might melt faster, and the fragrance might not last as long.

Tips for making your wax melts last longer

  • Start with a clean wax melt warmer.  Avoid any leftover residue interfering with the new wax melt.
  • Use a wax melt warmer that matches the size of your wax melt. This helps the wax melt evenly and efficiently.
  • Keep your wax melts away from direct sunlight or heat sources.  Too much heat can cause them to melt too quickly.
  • Experiment with different fragrance concentrations. Find the right balance between a long-lasting scent and a pleasing strength.
  • Store unused wax melts in a cool and dry place.  Preserve their fragrance and prevent them from melting prematurely.

How Often Should I Change Wax Melts?

Change wax melts every 20 to 30 hours of burn time, ensuring you consistently enjoy their optimal fragrance and performance. In addition, the wax becomes hard and more difficult to clean up after extended use.

Changing wax melts regularly is important to keep your space smelling fresh and enjoyable. Let’s explore how often you should change them and what factors can influence the frequency.

Why changing wax melts is important

Over time, the fragrance of wax melts can fade as the fragrance oils are released. Changing your wax melts allows you to enjoy a vibrant and pleasant scent in your surroundings. 

Additionally, as you use wax melts repeatedly, they can gather dust or lose their original strength, resulting in a less desirable scent experience.

Factors that affect how often you should change wax melts

Personal preference

How often you change wax melts depends on what you prefer. Some people like to change them every day to experience different scents, while others prefer less frequent changes. Think about how much you enjoy different scents and how often you’d like to switch them.

Strength of the fragrance

The strength of the wax melt’s scent can also impact how often you need to change them. If you like a strong and intense scent, you might find that the fragrance fades more quickly, requiring more frequent changes. 

On the other hand, if you prefer a milder scent, the wax melts might last longer before needing replacement.

General recommendations for changing wax melts

Daily or frequent changes: If you enjoy trying out new scents often or want a consistently strong fragrance, consider changing your wax melts every day or every few days.

When the scent weakens

Pay attention to how strong the scent is. If you notice a significant decrease in the fragrance’s intensity, it’s a good sign that it’s time to change the wax melt and put in a fresh one.

When the wax melt stops working

If you can’t smell any fragrance from the wax melt anymore, it’s likely that it has lost its scent and should be replaced.

When following these suggestions and considering your personal preferences, you can figure out how often to change your wax melts and keep your space smelling wonderful and inviting.

Factors That Affect How Well Wax Melts Work

Did you know that some things can make your wax melts work better and make your room smell fantastic? 

Let’s find out more about these factors and how to get the most out of your wax melts!

Room temperature

The temperature of the room where you use your wax melts can affect how they perform. If the room is warmer, the wax melts faster and gives off a stronger smell. But it might not last as long. 

Alternatively, if the room is cooler, the wax melts slower and the scent lasts longer, but it might be milder. You can try adjusting the room temperature to find the balance you like.


Having good airflow in the room helps the smell of the wax melts spread around. When the air moves, the fragrance can reach all parts of the room and make it smell nice. 

Opening windows or using fans can help the air circulate and spread the scent evenly.

Where to Put The Wax Melt Warmer

Where you place the wax melt warmer also matters. It’s best to put it in the middle of the room or where you spend most of your time. 

This way, the scent can reach everywhere. Avoid putting it where the air doesn’t move much or where there are drafts, as the smell might not spread well.

How to Select the Right Wax Melt Warmer

Select a wax melt warmer by considering the heating source you feel more comfortable with (electric burner or tealight) and the design style you prefer. Always compare the temperature control features and safety features before buying.

Choosing the right wax melt warmer can greatly enhance your wax melt experience. Here are some factors to consider when selecting the perfect wax melt warmer for you:

Design and Style

First, think about the design and style that matches your taste and complements your home decor. Wax melt warmers come in various shapes, sizes, and materials, including ceramic, glass, or metal. Consider the aesthetics and choose a warmer that adds a touch of beauty to your space.

Heat Source

Wax melt warmers use different heat sources to melt the wax and release the fragrance. Common types include electric warmers, tea light warmers, and bulb warmers. Electric warmers provide consistent heat, while tea light and bulb warmers require a separate heat source. Decide which type of heat source is most convenient and safe for your needs.

Temperature Control

Some wax melt warmers offer temperature control settings, allowing you to adjust the intensity and duration of the scent release. This feature is beneficial if you prefer a milder or stronger fragrance. Consider whether having control over the fragrance intensity is important to you.


Ensure that the size and shape of the wax melt warmer are compatible with the wax melts you plan to use. Some warmers are designed specifically for certain types of wax melts, while others are versatile and can accommodate a variety of sizes and shapes. Check the product specifications to ensure a proper fit.

Safety Features

Safety should be a priority when selecting a wax melt warmer. Look for warmers with safety features like an automatic shut-off timer or a stable base to prevent accidents. These features provide peace of mind, especially if you plan to leave the warmer unattended for extended periods.

Reviews and Recommendations

Take advantage of online reviews and recommendations from other wax melt enthusiasts. Read about their experiences with different wax melt warmers to get insights into their performance, durability, and overall satisfaction. Their feedback can help you make an informed decision.

When considering these factors, you can choose a wax melt warmer that aligns with your style preferences, suits your needs, and enhances the longevity and fragrance diffusion of your wax melts. 

Remember, the right wax melt warmer can elevate your wax melt experience and create a cozy and inviting ambiance in your space.
