ABSTRACT An article is disclosed which is suitable for wiping hard surfaces such as glass to give a streak-free finish. The article comprises a substrate (preferably paper or non- woven fabric) carrying a homogeneous aqueous composition having a surface tension below 45 mNm-1 and which on drying does not form discrete droplets or particles larger than 0.25 /um. The liquid composition advantageously includes a (preferably nonionic) surface-active agent and a partially esterified resin such as a partially esterified styrene/maleic anhydride copolymer. The article may be wet (for example, coated or impregnated with the liquid composition) or dry up to the point of use (for example, the liquid may be within pressure-rupturable microcapsules). Preferably the article is produced by a process which includes prewashing the substrate to remove any potentially streak-forming impurities.
