I've used baby wipes, Mr. Clean magic eraser, Apple guard as I was restoring a LV, and had amazing results, i would post a photo but am not sure how to. I had no cracking issues and the leather is not dry either. I did condition it three times, so that may be why. But I decided to take the chances, as my bag had some weird over spray on the handles. I believe the lady before me did not like the honey colour of the handles. Any way my bag looks amazing now! just for reference my bag was made in 2010, only making it 4 years old and I only paid $200 for my speedy 30 that came with the bag, box, dust bag and receipt.
The handles and the brass were the only issues. I wiped the bag down with baby wipes and was disgusted at the amount of dirt that was on the bag! for the brass I used Crest 3D white tooth paste with q tips. For the zipper I just put the toothpaste on a soft baby tooth brush. After I went over all the brass with brasso very carefully and my brass is beautiful!! I must have spent ages on those handles tho
First I started with water on a cloth and cleaned that horrible over spray off! came off quick. Then I went in with the ME and had a bunch of brown come off again ( I wet my ME) and then went in with baby wipes on the handles and bag and had more brown come off. Lastly I went in with Apple Guard cleaner and was shocked that more of this brown was coming off. I did that until no brown came off and my bag looks better than ever. Conditioned it 3 times with my hands with the apple guard conditioner and I have a slight sheen to it but am still looking on how to get a shine back to the vachetta!
