A liquid type, highly alkaline, chelated detergent for the food industry In a chelated detergent, agents built into the formulations react to calcium and magnesium ions in water by surrounding and converting them to soluble compounds, or a non-clinging floc. They are thus prevented from depositing out as scale, an important consideration in hard water areas. The chelating action of SUPERWASH 500-LR makes it especially applicable in bottle washing operations. Besides controlling scale, it eliminates the problems of excessive drag-out and bottle haze.
