Abstract
A method for cleaning a surface of an external wall of a building includes applying a cleaning fluid containing a strippable film forming agent to the surface of an external wall of a building, drying the applied cleaning fluid to form a strippable film, and stripping the strippable film from the surface of the external wall. Thus, the cleaning fluid which contains soil is removed with the strippable film, so that the scattering of the cleaning fluid around the building can be prevented.
Claims9
A method for cleaning dirt from a surface of an external wall of a building, comprising the steps of applying an aqueous cleaning fluid having a solid content including a strippable film forming agent and a surfactant to the surface of the external wall of the building;
- drying the cleaning fluid applied to the external wall to form a strippable film;
- and stripping the strippable film from the surface of the external wall to remove the dirt from the surface of the external wall captured by the strippable film, wherein said strippable film forming agent consists essentially of a water soluble polymer selected from the group consisting of water soluble natural polymer and a water soluble synthetic polymer, wherein said water soluble natural polymer is selected from the group consisting of gelatin, casein, albumin, starch, dextrin, alginate salts, gum arabic, pectin and gluten, and wherein said water soluble synthetic polymer is selected from the group consisting of carboxymethylcellulose, methylcellulose, ethylcellulose, hydroxyethylcellulose, polyvinyl alcohol, polyacrylamide, polyvinyl pyrrolidone, polyethylene oxide and polyethylene glycol.

- drying said cleaning fluid applied to the external wall to form a strippable film;
- brushing the strippable film from the surface of the external wall to remove the dirt from the surface of the external wall captured by the strippable film;
- and
- washing the external wall with water.
