Abstract
Abstract A water based cleaning composition including a major portion of water, a minor portion of a cleaning agent such as ammonium hydroxide or a lower alcohol such as isopropanal and a small portion of a polyethylene and alkoxy polyethylene glycol of high molecular weight and triethylene glycol which not only acts as a lubricant but has a preferential affinity for glass and the like as compared with oil, grease, dirt and/or lubricity component such as ammonium bicarbonate or ammonium carbonate.
