Best way to remove sticky residue/adhesive from painted surface?
I have a window ac unit that requires a net to be stuck to the window for the hose to go through. The sticky back Velcro they provided to attack the net to the window was coming off so I’ve decided to take it all down now the heat waves in the uk are calming down but they’ve left a horrible thick sticky residue behind. The window is a velux so the residue is on a painted wood surface. I googled it and I’ve tried warm soapy water and I’m currently working my way round with cooking oil which is doing it but it’s taking a painfully log time to do. Is there any quicker working methods or residue remover that won’t damage the painted wood? Thanks!
