Wow!!! I'm going to have to do that to the bag my husband bought me at the Unclaimed Baggage Center in Alabama. It's a Mia in berry sateen and has some pretty bad grease stains on the bottom and a small one on the back. I've tried everything but the washing machine, but I'll do it now that I've seen your results!
Thanks!
Have you tried Goo Gone? It's supposed to remove grease stains but I've never tried it myself.
Using the washing machine is a pretty desperate manuever, but if I have tried everything else and I still don't feel comfortable carrying the bag because of the condition - then I think it is worth a try. But you have to be prepared that it may not work and it might even make things worse.
I feel that it is easier to try "extreme cleaning methods" when the bag was inexpensive; but I would find it hard to "play rough" with a bag that costs a lot of money. But again, if I can't carry it because it is soiled than I might as well try to clean it!
Good luck with your rehab!
