A spraying device comprising a reservoir and a nozzle linked by a path is used to apply an aqueous cleaning composition to a surface. The interim dimension of the path is located immediately upstream of the nozzle. The composition comprises abrasive particles, wherein substantially none of the particles has a maximum dimension which is more than half of the minimum dimension of the path and none of said particles have a dimension greater than said minimum dimension.

Sprayable abrasive cleaning compositions

A chemical cleaning composition for silver- or copper-containing surfaces consists of a water-soluble solid or powder comprising thiourea or a derivative thereof, and is formulated in unit application form, e.g. in tablet or sachet form. A preferred composition comprises up to 60% thiourea or a derivative thereof; up to 4% surfactant; not more than 40% acidifier; less than 20% disintegrant; up to 10% binder; 0-1% lubricant; and up to 40% diluent.
