I use a Tusting case that I've had for a while now and noticed some small spots on my hip that I believe was some polish transfer from my bag rubbing against my hip when I used the cross body strap. I cleaned it, applied some oil, let it dry, repolished. I noticed another spot on my hip today so I buffed it some more. When I go over it with a clean white cloth I am still seeing small amounts of polish being picked up on it. I've been at it for a while and I am still picking up color with a white cloth. Anyone have a suggestion on what I need to do? Update: I went over the bag with almost a box of isopropyl wipes and it seems that the amount of dye being picked up by the wipes is decreasing. My plan is to do this for a while longer then later condition the bag.
