We have recently rec'd, at the Castle Rock Museum, in Colorado, numerous vintage medical and prescription bottles. They all appear to be innocuous, they are empty, with the exception of two bottles, 18 oz. of Watkins Coconut Oil Shampoo. I am wondering what would be the best method for disposing of this liquid shampoo. Can it simple be poured down the sink? We don't care to keep the liquid, only the bottles.
