The invention provides a liquid abrasive cleaning composition of pH 7-13 which comprises: a) 0.1-20 wt.% of one or more surfactants forming a suspending system, b) 2-80 wt.% one or more suspended abrasives, c) 0.5-10 wt.% of a C2-C6 alkanolamine, and, d) 0.25-10 wt.% of a hydrocarbon co-solvent. The alkanolamine acts both as a base and a solvent which improves cleaning and so allows the level of suspended abrasive to be reduced so as to reduce the possibility of damage to surfaces and improve rinsing performance. It is believed that the presence of the hydrocarbon co-solvent is required to maintain the stability of the compositions at extremes of temperature.
