TweetTry removing some of the BA. Mix 1cc gear in a syringe with 1cc sterile water. Mix them up good for 1 minute and let sit with pin down for 12 hours. After 12 hour, maybe less, the oil has separated from the BA/sterile water. The sterile water takes the BA from the gear. Now, shoot the layer out and left is pure Deca or whatever you have. Might be some BA left, but nothing much. Just make sure you shoot it after this method, because it will get un-sterile in time. Always worked for me. Very easy.
