As with most sticky material, heating up the surface will help you to remove the decal much easier. If working on a vehicle, you can place it in the sun for a bit which should be enough to help get the process going. Many installers choose to use hairdryers or heat guns and these are an easier option if working indoors. Just be sure not to get the material too hot with the heat gun as you don’t want the vinyl melting. Always work in sections, heating up the entire surface at once will be a waste of time due to the fact that once you get to the next section, it will have already cooled down.
Once you’ve applied the heat, you should be to begin scrapping back the vinyl. For this part I use a plastic razor blade or credit card. DO NOT USE METAL! This will only cause damage to whatever surface your decal is on (particularly vehicles). You don’t need to scrape the entire decal back, just enough to be able to get a good grip on it when peeling off.
Once you’ve got your edges peeled up, you can begin peeling the material back. You want to do this SLOWLY, fast motions will likely cause the material to rip or leave excess glue behind. I also suggest you do this at about a 120 degree angle again to avoid ripping and this helps to ensure you’ll remove the whole decal at once.
REMOVE THE GOO
Once you’re done removing the decal you’ll probably notice a nice dirty/sticky outline of where your decal was. There are a variety of different products you can use to remove this but I am a fan of goo be gone. Be sure to read the back of the bottle before use to make sure it will not cause any damage or discoloration to whatever surface you are working on before you start. I apply the liquid with a terry cloth as it is tougher and will work better to remove any tough grime. You may need to wipe the surface down a few times but in the end you should have a nice and clean surface ready for your next decal project!
