Hi, I was wondering if someone can help? About 6 weeks ago I made some CS to take with me on a trip. I made it with a silver puppy and it was perfectly clear and seemed potent. I put it in a Rubbermaid plastic water container and carried it with me. After about 3 weeks on the road it turned a brownish color. Can anyone tell me why this happened and if it is still good to use?
Thanks. PT
