Tiki torches add a tropical flair to a patio or outside garden area. Standard tiki torch fuel -- which helps ward off mosquitoes -- is available at local home and garden centers. Homemade tiki torch fuel provides light, but does not have the ingredients to keep mosquitoes at bay. A simple oil lamp fuel made from isopropyl alcohol and distilled water will burn in a tiki torch. Pure olive oil or coconut oil will burn clean in a tiki torch and do not require mixing.
Measure one tsp. of distilled water. Pour the distilled water into the 16-oz. bottle of isopropyl alcohol.
Replace the lid on the bottle. Shake to mix.
Add a fragrance to the fuel, if you choose. Add 1/2 tsp. of essential oil, such as lavender or rose. Shake to mix the contents.
Pour the homemade fuel into the fuel chamber of the tiki torch.
