Use caution when working with naphtha as it is very flammable. Do not use it near an open flame. You could also use acetone, commonly known as nail polish remover, in place of naphtha.
A homemade solution will be free of many harmful chemicals that are found in commercial adhesive removers. You can add a few drops of sweet orange essential oil for extra degreasing power and a more pleasant scent.
Paper stickers will allow an adhesive remove to penetrate the paper surface. Plastic stickers will repel the adhesive remover and not allow it to reach the sticky adhesive surface on the back of the sticker. It is important to try to remove as much of a plastic sticker as possible before applying an adhesive remover. Be careful to not lift any of the guitar’s finish while attempting to remove the sticker.
If you are using a spray bottle of adhesive remover, spray the cloth or paper towel instead of the guitar. This will prevent you from getting remover in parts of the guitar where you do not want the remover.
