Re: fresh or aged urine for teeth whitening?

Hello. I realise this reply is late and thread is dead. However it may help someone else. Urine aged for a year could be used to bathe in. Dump it into the bath water. I have aged Urine before sometimes it develops mold, I don't use that urine. Sometimes the Urine doesn't form molde, I think it has to do with the exposure to the air. Exposure to air urine seems to develop molde, air tight sealed urine seems to last longer. Tweet
