ABSTRACT:
An alkali metal cleaning composition for cleaning metal and for inhibiting corrosion of metal. The composition is composed of an alkali carbonate salt, a surfactant, and a corrosion inhibitor. A preferred corrosion inhibitor is an alkali metal silicate. Additional metal corrosion inhibitors such as a combination of a triazole compound and an alkali metal borate also can be employed. Such alkali carbonate compositions are readily water soluble and remain in solution over prolonged storage periods.
