Abstract
Abstract The invention relates generally to products useful for home laundering, and more particularly to a product which incorporates a prespotter with a detergent and having one or more of the following separate functions: detergency, fabric softening, stain removal, bleaching, and bluing; with the advantage being that both the detergent and the prespotter are uniquely packaged together as one product, negating the need to purchase and store separate products for each end use function, and also, unavoidably providing presentation of the prespotter to the detergent user at the time of laundering. The invention also concerns methods of use of such products during laundering.
