How to clean vintage Gucci bag

  1. Does anyone have any tips on how to clean a vintage Gucci bag? i recently purchased one for around 40$ and was told at the Gucci counter that to send out would be $150....which i dont really wanna spend. the inside seems to be the worst, its fabric that i would love to machine wash, but cant kuz i dont want to ruin the leather. it also needs much more than a spot clean...the whole thing really needs to be laundered. any tips on how? Thanks!
