A T-shaped squeegee for any smooth surface, contoured or flat, comprises a thin elastic cleaning element with two parallel cleaning edges, a supporting curved and protruding rigid blade that can produce continuously varied curvature by changing the angle of attack, a handle, and holder that connect the blade and the handle. This combination of thin elastic cleaning element with channel shaped cross-section and contour matching ability of the blade provides sufficiently high contact pressure on a wide curve for removing tightly adhered dirt, efficiently.
