Abstract
Aqueous acidic thixotropic hard surface cleaning formulations, having a viscosity of 2000 to 10,000 centipoise containing on a weight to weight basis: (a) 0.5 to 6.0 percent of hydrated aluminum silicate that is substantially free of inert mineral impurities; (b) 0.1 to 3.0 percent of an amphoteric material or a highly alkoxylated block copolymer; (c) 0.1 to 5.0 percent of a nonionic surfactant selected from the group consisting of polyoxyethylene derivatives of higher alcohols and polyethylene glycol ethers of linear alcohol; (d) sufficient acid to establish a pH in the range 0.9 to 3.5; (e) 5.0 to 50.0 percent of an abrasive; (f) 1.0 to 5.0 percent of a cleaning solvent; and (g) sufficient deionized water to make 100 percent.
