Spray Bottle Size for 10 Drops of Essential Oil

Q: There is a disinfectant recipe by Melissa Maker. The recipe did not mention the size of the spray bottle for ten drops of essential oils. I am always looking for non toxic cleaning ideas.

A: Typically 750 ml to 1 L is a good guide. Having said that, essential oils are not harmful and the amount of oil added will affect the smell more than anything, but I wouldn't go under 10 drops so that the disinfecting properties can be utilized.
