hi ive just made a silly mistake and was wondering if anyone out there had any idea how to help..ive recently decorated my hallway and also put a new radiator cover over the radiator. before doing this i stained it with RONSEAL QUICK DRYING VARNISH unfortunately without realising it i placed the item on the radiator just before it was completely dry and now i have 2 lines of about 3 inches in length of quick drying stain on my lovely beige wallpaper...would anyone know if or how i can remove these?? is there anything i can do without having to rehang new drops??..many thanks if u can help
