Abstract

A method for cleaning structural surface (1) by forming a substratum membrane (17a) thereon through application and drying of a thin layer (16) of aqueous solution (5) of membrane-forming polymer (2) on a structural surface, spreading a fibrous reinforcing member (15) on the thin layer (16) before drying or the substratum membrane (17a) after dried, and the aqueous solution (5) is applied on the outer surface of the reinforcing member (15) while wetting it in such a manner that, upon drying, an overlying membrane (17b) integral with both the substratum membrane (17a) and the reinforcing member (15) is formed so as to generate a multi-layer membrane (18) having the substratum and overlying membrane sandwiching the reinforcing member. After causing foreign matters (8) on the structural surface (1) to adhere onto the substratum membrane (17a), the multi-layer membrane (18) is peeled off from the structural surface (1).
