i don't want you guys to try it unless you're comfortable doing this....
i waited for 3-4 months to do this!!! i used baby wipe to clean the dark marks....and they came off clean! i use baby wipes on all my LVs, but i normally wait until it starts to develop patina --- ever since then, the dark marks seem to be slowing donw on the appearance plus the leather itself is nice honey color now!!
for years i used pampers non scented ones, but i recently switched target brand's non scented one.... they are bigger and stronger, LOVE their baby wipes!! lol
