TLDL: In this episode I show you how to make your own mouthwash. Simple. Takes 2 minutes!
Working out the costs after buying the ingredients from scratch cost me $380hkd or (in a straight conversion, so it might be cheaper locally for you) £40 or $48USD. With this I can easily make around 6 litres of mouthwash. How much does 6 liters of conventional mouthwash cost you?
