Final answer:
In a multistep cleaning process that uses alkaline detergents to reduce corrosion, the step that follows the alkaline wash is an acidic wash, which helps remove inorganic deposits and neutralizes the high pH of the alkaline cleaner.
Step-by-step explanation:
To reduce the potential of corrosion, highly alkaline detergents should be used in a multistep cleaning process, which includes first an alkaline wash, then an acidic wash, and finally a regular rinse. Alkaline cleaning agents, which contain strong bases like sodium hydroxide, are effective at dissolving fats, oils, and protein-based substances. Acidic cleaning agents are primarily used for removing inorganic deposits such as scaling and feature active ingredients like strong mineral acids and chelants. These cleaners may also contain surfactants and corrosion inhibitors. After these cleaning steps, neutral washing agents might be used for their pH-neutral characteristics based on non-ionic surfactants that help disperse various types of dirt without contributing to corrosion or other chemical reactions.
