I would soak them in a dillute solution of bleach (1 tablespoon of bleach per one gallon of water). Give them at least 20 minutes and make sure the bottles are full.
Otherwise, you can soak them in PBW which is really good at removing deposits. Then hit them with an iodine (iodophor) sanitizer or oxygen sanitizer like ez clean or one step.
