Put together this 30 second video a while back, it’s worth seeing if you want to know how easy it can be to remove graffiti using our graffiti resistant films on signs. Using some rubbing alcohol on a paper towel, the tagging was gone in moments.
Demonstration of removing graffiti from a vinyl film laminated with Concept 108 Tedlar Anti-Graffiti film. Graffiti sample had been on the film for about 2 weeks, and is removed with the proper solvent. I try three solvents as a test.
A vendor of a graffiti-resistant clear topcoat we use has put together this quick video about graffiti removal. I always recommend starting with the mildest cleaner you can use. Harsh solvents can damage the topcoat and make it less effective later. Rubbing alcohol has been effective, and it’s the solvent I recommend starting with. Also, always test in an inconspicuous area and observe the results before going ahead with full cleaning.
