Sanitary Certificate Wash bottles?
These bottles are produced in a food safe environment and are considered ready to use.
We do have some customers wash them or some customers have air blown into the bottles on their filling lines just to make sure there isn’t any foreign matter in the bottles.
Most customers use the bottles right out of the box.
If you do wash a plastic bottle or bear, DO NOT do it in a dish washer. Dish washers use water temperatures that will cause the plastic to deform.
