Custom Rear Window Decals – Custom decals are a great way to customize the look of any car window or glass surface, but removing them can sometimes be difficult. If you have removed the label and left behind sticky glue and a gloomy shadow sketch, there are some simple tricks you can use to restore the window to its original state. Pre-treatment of the surface for the cleaning process.
Fill your spray bottle with white vinegar and apply it generously to the area until the pieces of paper and sticky adhesive are immersed in the solution. Leave to soak for five minutes. The vinegar will begin to break the custom rear window decals glue so that it will be easier to remove. Loosen the glue when interrupting with your scraping tool. Use the tool to gently push around any glue and loose debris. If any of the adhesives become loose enough to remove, scrape and dispose of properly.
Remove the dark shaded area and any remaining adhesive using WD-40. Apply a thick layer of lubricant to the entire affected custom rear window decals area. Allow it to soak well for about two minutes and then remove the adhesive from the use of your scraping tool as you did before. The lubricant should loosen the remaining adhesive so that you can easily remove it. Clean the glass to restore the window to its original state.
