Title: Liquid abrasive cleaner

Abstract: The invention relates to a surface adherent abrasive liquid cleaner which is especially useful for removing hard water, iron and organic stains as might be found in toilet bowls. The cleaner includes a mineral acid such as hydrogen chloride to aid in dissolving the stains. An abrasive is suspended in the cleaner to aid in mechanically scrubbing off the stains. A particular suspending agent comprising hydrophillic silica, at times used in combination with a secondary suspending agent preferably comprising an metal silicate, forms a part of the cleaner. Sufficient of the suspending agent is used to make the cleaner free-flowing and to stably suspend the abrasive but still to leave the cleaner viscous enough to adhere to a smooth surface such as porcelain and to the stains. A non-ionic surfactant forms a part of the composition. An effective disinfectant can also form a part of the composition.
