Stunning color revealed by cleaning green glass crown top soda bottle

When do you tumble a bottle or have it professionally cleaned? Does it have to be super old to be worth cleaning? Does it have to be exceptionally rare to be polished? The answer is anytime you want to restore the original luster the glass had when your bottle was manufactured. In this case a tooled crown top bottle in an amazing citron green color is worth a light polish for sure. Staining and light oxidization made this bottle absorb light instead of letting it shine through displaying the vivid color.
