If you want a real nice golden honey coloured patina, it takes about a year (in general). I remember when I got my first LV, I used solely that bag 1-2X a week for one entire year. However, if you use your bag DAILY, then you can achieve the same effect within 1/2 year. Of course, oxygen is the main factor and sunlight (heat) is the catalyst.
Also, I won't recommend baby wipes on brand new LVs cuz they're VERY drying and I don't know how you moisturize the leather lol.
