In this video Danny Lip ford is showing how you can convert an old sponge mop into an inexpensive pole sander for your household purposes. For this, take an old sponge mop and remove the sponge from it by loosening the screws. Then cover the rectangular sponge fully with the sheet of sand paper. Now screw back the sponge with sand paper to the head of the mop. You can do your sanding in the wall very easily now. If you were to use just a sheet of sandpaper and sand the wall, it would take a lot of time and would be very difficult to do. Hence by putting the sand paper on a sponge mop, you can do the sanding better and easily.
