To use eco soy wax melts, place one or two wax melt cubes into the dish of a wax warmer (either electric or tea light). The wax will melt and release the fragrance, filling your space with a pleasant aroma. When the scent fades, simply remove the old wax and replace it with a new melt. 

Here's a more detailed breakdown:

1. Choose your warmer: Wax melts can be used with both electric and tea light warmers. Electric warmers are generally considered safer due to the absence of an open flame. 

2. Select your wax melts: Choose a scent that appeals to you and fits the mood you're trying to create. 

3. Prepare the warmer: If using an electric warmer, plug it in. If using a tea light warmer, place a tea light candle inside the designated area. 

4. Add the wax melts: Place one or two wax melt cubes into the dish of the warmer. No need to add water. 

5. Enjoy the fragrance: As the wax melts, the fragrance will be released. Sit back and enjoy the aroma. 

6. Know when to change the wax: The wax will not evaporate, so the fragrance will fade over time. When you can no longer smell the fragrance, it's time to change the wax. 

7. Remove old wax: You can remove the old wax by heating it up for a minute or two and then using a paper towel to soak up the melted wax. Alternatively, you can use cotton wool balls to absorb the melted wax. Dispose of the old wax properly. 

8. Replace with new wax melts: Add fresh wax melts to the warmer and repeat the process.
