The world of vinyl lettering often leaves us with the task of removing glue residue from a surface after removing old vinyl letters. The next time you’re faced with this project, try this: Add a few drops of mineral oil to the solvent you choose—alcohol, thinner, acetone, mineral spirits, etc. These are oil-based as the glues usually are.
