This should be done only if you are confident you will not harm the vehicle or plate. Then, using your screwdriver, remove the screw. Repeat with remaining stubborn screws.

  • Lubrication

Spray enough WD-40 round the screw and use the same approach to work the grease into the threads. If you have tough corroded screws, a lube designed for this purpose may be preferable to WD-40. After spraying the screw with lubricant, let it sit for a couple of minutes before unscrewing it again. When nothing happens, repeat the spray and allow it to rest for about 30 mins. Then, use extra elbow grease, and attempt to loosen the screw.
