    Abstract: Stable, silicate-free, soft metal safe, alkaline cleaners are provided. The cleaners comprise calcium ions and surfactants containing hydroxyl and/or carboxylic acid groups or a combination thereof, wherein the total of the two functionalities in each surfactant is greater than or equal to 2, and alpha-hydroxy carboxylic acids. It has been surprisingly discovered that alpha-hydroxy carboxylic acids such as tartaric acid, are capable of keeping calcium ions in an alkali solution. The cleaners may also comprise nonionic surfactants to provide wetting, detergency, and foamability where required, anionic surfactants as viscosity enhancers in the case of high retention cleaners, and solvents such as alcohols, glycol ethers, or hydrotropes to enhance solubility of the system. The alkaline cleaners are safe to use on soft metal surfaces and equipment commonly found in many industries, without the presence of silicate which is normally used as a corrosion inhibitor.
