Abstract
A thixotropic cleaner comprising about 6 to 12% of a precipitated silica; about 0.05 to 2.5% of a cationic, nonionic or zwitterionic or amphoteric surfactant, or mixtures thereof, that has the ability to hydrogen bond and mixtures thereof; an acid; and an abrasive. The relationship between the relatively narrow ranges of precipitated silica and hydrogen bonding surfactant is critical and responsible for the favorable viscosity, ability to suspend abrasives, and minimal or lack of syneresis. All of these advantageous characteristics are stable over an extended period of time.
