I use citricidal for more than 5 years and I'm completely satisfied. I use it everywhere. I use it to prevent flu or common viruses infections to sterilize utensils (bottles jars and tools) that I use for homemade cosmetics and as a preservative in my home cosmetics. I take citricidal with me on trips and I feel "safe" since I feel that I carry an entire pharmacy. I give it to my child from the age of 10 years and since then I feel that citricidal can prevent the common flu and digestive issues.
