The interior of my 99 sunfire gt is white and blue. It was painted with Krylon Fusion and the vinyl parts were dyed using Duplicolors spray dye. I haven't been able to get the interior clean on the vinyl passenger door handle and surrounding plastic white areas. It's a really dirty brown. Does anybody know what kinds of cleaning supplies I can use on this? The only thing I could really think of was maybe simple green but i'm not sure. Any help would be appreciated.
