Permanent marker some biro and sticky stuff left from stickers can be removed with spray deodorant like linx type stuff not any with powder in and it works best on non porus materials as the alcohol will slowly thin the stuff first
i have used it on glass paint plastics ect with spot on results best with permenent marker and sticky stuff
With left over sticker stuff spray enough to soak the mess then use a finger and nail combo to rub the glue and it will melt and get stickier then wipe off with a tough cloth I use a bit of denim and repaeat until there is none left beware it will spread out a bit before it starts to come off I've never used a sticker removal stuff as I woulnt want it on my skin therefore paint
Permanent marker will vanish with one wipe
