Recently we had to remove some old graphics from stainless steel elevator doors. When we removed the graphic it left the adhesive behind. We used adhesive remover to clean the residue off, but it seems to have had an effect on the doors making them look like they are stained. In this case they were being re-wrapped, but I am wondering for future has anyone ever run into this and do you have a solution for bringing the stainless steel back to it's original state. Cheers
