I put up some temporary paper shades with the stick-on backing that were positioned on the vinyl part of my windows. After a good 6 months I finally needed to remove them. However while the paper ripped off, a lot of the glue itself remained. I tried both water and alcohol and a lot of rubbing and scraping, but the glue still remained. The only thing that saved me was that the new shades that were put up covered the left over glue (which I accept, but it bugs me)
I have some more paper shades to remove in the nearish future and expect the same amount of left over glue. Given that the shades are stuck to a vinyl window, what would be the best solution to remove this sort of glue?
Note that this residue is on the vinyl part of the frame of the window, and not on the glass
And I am looking for solutions that are readily available in the USA
