Abstract
The invention is a foam stabilizing composition which is used in conjunction with alkaline detergent products to produce a foam which is capable of clinging to vertical surfaces for extended time periods without breakdown or drying and which ultimately rinses freely with water. The foam stabilizing composition generally comprises a vinyl polymer emulsion. The invention also comprises a method of cleaning hard surfaces using the combination of the alkaline detergent product and the disclosed foam stabilizing composition.
