The detergent composition for food processing equipment and / or cooking equipment described in Patent Document 1 contains an alkali metal hydroxide as an alkali agent.
However, from the viewpoint of safety of workers, an alkaline cleaner containing no alkali metal hydroxide is desired.
Generally, alkali metal hydroxides easily act on oil stains and have an effect of enhancing the detergency, and therefore alkaline detergents that do not contain alkali metal hydroxides tend to have reduced detergency.
