Agree ~ just hold the hair dryer about 3" away from the decal...on high-heat, move it back-n-fourth over the entire decal for a couple of minutes. Choose a corner of the decal and start picking at the edge to release a big enough piece to start pulling/removing the decal ~ continue applying the heat using the hair dryer as you pull/remove the decal. Typically, you will not have any glue residue.... but if you do, saturate a cloth with some glue-be-gone (or equivalent) and go over the visor. It may take a little work, but the residue will come off and the glue-be-gone will not hurt/stain the visor. Leave the windows open to let the car air-out... vapors are kind of strong. In this case, while options are good ~ IMO, no decal is better than a cover-up.
