Methods, systems and devices for protecting a surface of a container from exposure to additives

A method of protecting an inner wall surface of a vessel from damaging interaction with an additive added to the vessel, the method comprising:

• providing the vessel at least part way filled with a liquid product;
• applying a force on the vessel sufficient to create a change in shape of a surface of the liquid product;
• starting a dwell time period at a predetermined time by sufficiently removing the force such that the force no longer creates the change in shape of a surface of the liquid product, the change in shape of the surface of the liquid product persists at least in part for a residual time period after removal of the force;
• ending the dwell time period by reapplying the force sufficient to once again create a change in shape of a surface of the liquid product, the dwell time period being less than the residual time period;
• and
• providing sufficient containment of the additive by the change in shape of the surface of the liquid product to substantially prevent damaging interaction between the inner wall surface of the vessel and the additive for at least an additive reaction time period at the end of which the additive is rendered substantially incapable of producing damaging interaction to the inner wall surface of the vessel.
