I have recently froze clean urine in a water bottle for future use. I plan on using this urine within a week and was wondering: 1) Is there anything I should be advised against when using this urine thats been frozen and thawed out in a plastic container? 2) I will shake the container and filter out any sediments with a coffee filter. Any other suggestions? 3) Anything else I need to know? PLEASE GIVE ME JUSTIFIABLE ANSWERS. THANK YOU ALL FOR THE HELP!!!
