How to handle with wasted vegetable cooking oils
to make a perfect candle

Recycling vegetable oils is easy, clean and fast

Learn how to treat, easily and economic, wasted vegetable cooking oils or out-of date cosmetic oils:

1

Filter the wasted cooking oil after being used and before storage, to remove water and food particles, using a coffee filter, a fine-mesh strainer or even a nylon stock. Store the oil in a properly sealed bottle.

2

Let the wasted oil stand for 24 hours so that the oil and water separate, forming two layers (water on the bottom and oil on top).

3

If you do not follow these procedures, the candles burn and its scent could be compromised, with fungus possibly speeding up the wax’s decomposition.
