Abstract: Alkaline ware wash detergents containing an alkali metal alkalinity source and alkanol amine phosphonate scale inhibitors and methods of employing the same for superior cleaning efficacy and hard water scale control are disclosed. Alkanol amine phosphonates beneficially reduce scale build-up, including calcium carbonate scale build-up from alkaline detergents used with hard water sources. Methods of employing the detergent compositions are also disclosed.
