I used this method on my 5 month old speedy b. My God was it dirty! I couldnt believe how much dirt came out, even from the pipings! It also worked on some water spots the bag had. But I have to be honest, I didn't just wipe the leather. I gave the vachetta a good scrub. I don't baby this bag and use it for my two kiddos under one and a half and for travel. I believe this is why it had so much dirt on it, oops! I love a honey colored patina and don't care for the pale "like new" look. I think patina adds character to a bag. Will be using this method from now on.
