A device for providing a relatively constant rate of dissolution of a solid article () within it has one or more opening () to allow the passage of water. There is a flow pathway between said one or more openings and the solid article, which flow pathway is obturated by a water-permeable packing (), through which water must pass, in entering or leaving the device.

Device for providing a relatively constant rate of dissolution of a solid article within it

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 hard surface cleaner comprises: an ethoxylated quaternary ammonium compound comprising a C ; alkyl or alkenyl radical and a polyalkoxy chain having from 2 to 20 ethoxy groups and from 0 to 2 propoxy groups; a glycol ether and/or a C alcohol; and an anionic surfactant.

Hard surface cleaners comprising an ethoxylated quaternary ammonium compound and an anionic surfactant

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.
