Non acetone nail polish remover is working…am I damaging the vinyl?
I think you might find the Winsor-Newton product a better option because there is no scrubbing, the paints come off very easily and no shiny parts when you are done. I had tried a long time ago with non acetone and acetone and had very poor results. Also don’t use Goof off - it will take the paints off, but the vinyl never looks right afterwards. Winsor-Newton can be found at Walmart, or any arts supply section.
