Does anyone know if the Oxy10 will work on the vinyl of any doll? Or shoes? My 2 year old daughter got hold of a pen and wrote on her shoes and a baby doll's face! Also on the iron-on decal part of a cute t-shirt! I tried kitchen spray products, but hasn't come off any of these things yet! Laundry stain solutions don't work on the t-shirt iron-on either! Thanks.
