I have heard GREAT things to clean a
coach handbag with the inside lining and even the outside material...it's a carpet and upholstery cleaner called Tuff Stuff I actually heard about it in a video on YouTube and when I searched for it on the Walmart website I found it for $4 or $5 I forget which but it's worth it because I was reading the 58 reviews and all of them mostly were good ones... quite a few actually mentioned about how well it works on getting coach purses to look like brand new!! And it's probably less messy compared to other stuff you could use to clean like liquid soap or spray on stain remover because this is foam and you just spray all over and wait 30 seconds and rub it in and it disappears.. what's better than that!? I would take that over water and bubbles any day.. LOL especially since you have to sponge that up afterwards with a dry washcloth or towel...I'm sure you still have to probably wipe down the bag after the Tuff Stuff but not as wet probably as the soap I would think so probably less drying time.... can't beat that!!
and you can still use rubbing alcohol for any ink marks although I was told never use alcohol on any leather because it dries it out but on leather the dollar store spray stain remover might work good but I'm not positive about that part so don't hold me to that one...LOL leather is more tricky with chemicals so you have to be more careful...or maybe you could try baby wash for the leather? Only because it's not as harsh. I'm just guessing on the last part...I'm not too sure what to do to clean leather actually...but if anyone else happens to know feel free to add your input...
