On a recent trip down into a creek, I came up with about 50 bottles in various shapes, between 1 1/2 - 10 inches tall. They all have one thing in common, a hard film, possibly mineral deposits, brown in color. I took a shard with the film on it, and it took steel wool to get this stuff off. Is there a solution I can soak the bottles in to remove this hard film, and not damage the bottles?
