Abstract
The invention relates to rinse aid compositions useful in warewashing, that provide sanitizing properties and stain control. The rinse aids of the invention provide a highly active available chlorine source which is incorporated into solid systems containing sheeting agents. The chlorine source is sufficiently stable to permit manufacture, storage, distribution, sale and consumption without loss of substantial proportions of active chlorine, while allowing for a broad selection of surfactants.
