PURPOSE:To obtain the title composition useful for cleaning stains on a surface of a floor made of stone such as terrazzo by using an anionic surface active agent, a nonionic surface active agent, a hydroxyalkylcellulose, and a lower alcohol as constituents each in a specified amount and adjusting the pH to a specified value. CONSTITUTION:The title composition contains 1-5wt.% anionic surface active agent (e.g. a straight chain alkylbenzenesulfonic acid salt), 2-10wt.% nonionic surface active agent (e.g. polyoxyethylene lauryl ether), 0.1-2wt.% hydroxyalkylcellulose, and 1-5wt.% lower alcohol (e.g. ethanol) and has a pH of 9 to 12. |
