Method for cleaning a glass surface with solutions of dissolved pelleted components containing high molecular weight polyphosphates, carbonates and acid-forming substances

摘要

The invention relates to a composition suitable for use in cleaning panes of glass, consisting of a pelleted blend of surfactants, the composition containing:PP(a) a water-soluble alkali metal polyphosphate of high molecular weight with a P.sub.2 O.sub.5 - content of 60 to 70 weight %;PP(b) at least one alkali metal carbonate or hydrogen-carbonate;PP(c) at least one crystalline substance producing an acid reaction in aqueous solution; PP(d) at least one anion-active and/or non-ionic surfactant; andPP(e) at least one filler, if desired or convenient.
