Say you have a container half the size of a 3 oz calcium container, so roughly a 1.5 oz container. You want to fill this up with about 90% water and 10% betadine. It should look practically look like water, but maybe with a brownish tint to it. Then you can dip one side of the q tip into the container and pull the lower lip of your bearded dragon’s mouth down a bit and gently rub that side of the q tip On the side of the mouth and then use the other side of the qtip to dip into the betadine solution you made and pull down the other side of his mouth a bit enough to get the q tip in and rub that side of his mouth gently. Then you can keep the container you made and do this daily so you aren’t having to keep making it, it should last a while until you need to make more diluted betadine solution! I hope this helps
