Abstract
A method for manufacturing metal containers using a cleaning agent having a substantially neutral pH is disclosed. Lubricants and coolants used during the container forming process are cleaned from the surface of metal containers by using a terpene cleaning agent comprising d-limonene, alpha-terpineol, beta-terpineol, alpha-pinene, beta-pinene, alcohols of such agents or mixtures thereof. Surfactants may also be used to aid in the cleaning process. The organic component of the cleaning agent, as well as lubricants, coolants and aqueous components, are separated for recycling and re-use.
