A cleaning composition comprises:A) 1% to 10% w/w of a colloid-forming material,B) 0.5% to 10% w/w of a polymeric thickener,C) 1% to 60% w/w of abrasive particles, andD) a bleaching agent.Preferably, the colloid-forming material is a clay and the polymeric thickener is a copolymer of acrylic acid.Such a composition can stably suspend the abrasive particles and has the desired rheological properties for a cleaning composition for use on hard surfaces such as ceramic bathroom fittings and toilets.
