The blade (1) has one or multiple stripes (2) i.e. double folded stripes, made of rubber or plastic. Left, middle and right stands (6-8) are extended up to a surface to be cleaned during use. Two or multiple incisions (3, 4) are formed in a bottom side (5) of the blade and extended to a fraction of overall height of the strip during use. The stands are formed with different widths and different lengths. The stands comprise respective free ends (6A-8A). One of the free ends is deeply or less deeply extended than other free ends during use. |
