How to Remove Auto Dealership Decals
Use a hair dryer or heat gun to heat up the area where the decal is located. If the panel is plastic (on a Saturn, for example), use the hair dryer because it has a lower heat range. If you choose to use a heat gun, use it on the low setting. Slow heat beats fast heat in this case.
Once the decal is heated up, use a putty knife (the inexpensive plastic ones are perfect), credit card or your thumbnail to start scraping off the decal. Most of the adhesive should be loose at this point, so remove what you can.
When the decal is off, use Goo-Gone or WD-40 (yes, WD-40) to remove the remaining residue. Apply the Goo-Gone or WD-40 to a terry cloth towel or soft and rub it over the residue in a circular motion.
How to Remove Raised Auto Dealership Emblems / Dealer Nameplates
Use a hair dryer or heat gun to heat up the area where the emblem is located. If the panel is plastic (on a Saturn, for example), use the hair dryer because it has a lower heat range. If you choose to use a heat gun, use it on the low setting. Slow heat beats fast heat in this case.
Take some dental floss or fishing line and loop it around the emblem. Looping from the side generally works best as these emblems are often horizontal in orientation. This will cause you to cut through a narrower band of adhesive.
Slowly work the dental floss or fishing line around the emblem until the emblem is removed from the vehicle. Some dealership emblems can be stubborn. If the dental floss or fishing line is not cutting through the adhesive, persuade the emblem off with a putty knife or credit card.
Use Goo-Gone or WD-40 to remove any remaining adhesive residue from the vehicle. Finish clean-up with soap and water.
