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 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. <IMAGE>
