Sanding block/window squeegee.
Virgil Johnson
This is a really great sanding block and it doubles as an even better window squeegee. Used dish soap and water. Lather up the window, tilt this jewel at 45 deg and wipe away the grime. 1/8 red silicone rubber attached to 1/2" plywood with double face tape. Best results I have ever had cleaning the windows.
