I recently made a 50 mil bottle of e-liquid. It leaked in the bag I was carrying it in, so I rinsed the outside of the bottle. After rinsing the outside, I unscrewed the cap to rinse the threads and got a little tap water in it. It wasn't much, but still wondering. I have it in the desk cubby steeping and I can see a little white ring around the top of the liquid. I came down this morning, and moved the liquid around and the ring seems to stuck to the container. Is this any cause for concern? I don't want to pitch it, but I don't want to be vaping it if it should go to the bin. Thanks.
