Re: Teeth Whitening: How long to age urine for best ammonia content?

The longer you age it the better, i currently use 7 month old aged urine for external use and 50/50 with Distilled water for enemas. I have never known of Ammonia in urine to be toxic and i know people that use 2-3 year old aged urine that have no problems with using it. With aging it just keep it in a glass bottle in a dark place with a slight opening on the container.
