You can make homemade beeswax finish by mixing equal parts of olive oil and natural beeswax. Place the ingredients in a boiler or a Pyrex jug, in a pot of boiling water. The mixture has to fully melt. This may take some time but it’s important that it completely melts and mixes together.
When you are satisfied that the mixture has melted completely, remove it from the heat and pour it into a heat resistant container. Allow it to stand and cool. Once the substance has cooled, it is ready to apply to the leather. To apply the wax, you may need to rub it between your hands at first to warm it and achieve some elasticity. It should become similar in feel to a chap-stick.
After this texture is achieved, simply rub the wax over the leather surface. Leave it sitting on the leather for a few minutes, then buff the leather with a soft cloth. This traditional method has been used for centuries and will protect, waterproof and condition the leather.
