I've found that if I clean the area first with warm soapy water and wipe it dry, then I use regular windex window wash to wet the area, use a squeegee (SP?) gently, over the decal, to remove the windex. Start gently, then more pressure until decal is dry. Let it dry overnight and they seem to stay on well. Not sure about over other decals. good luck
