LJ, it's the pebble grain
BW: I have very little experience with leather cleaning/treatment products.
Dooney 'pebbled' leather is embossed with the grain, but not coated,
to the best of my knowledge. So, I would think that any product that was safe
for pebbled leather would be safe.... with
one concern..... the color.
White leather can darken or turn yellowish under some conditions.
Also, the white coloring may not have been applied the same way that
deeper colors were applied. So the color may easily be rubbed off or
lifted off by any chemicals. Even a baby wipe (which many ladies use
to treat dirt and color transfer) might disturb the white.
Bottom line, I'd be reluctant to treat this handbag. If you do decide to go ahead,
test the bottom or other area in case of problems.
Another option is to check the bag regularly for color transfer and use soap and water
on a damp cloth to remove the color transfer while it is fresh and still on the surface
and before it builds up. That is what I do with my Dooney white and bone handbags.
I also treat dark clothing by adding a cup of white vinegar to the wash the first few times
I launder the clothing. The vinegar helps set the color. It's not foolproof, but it helps.
Even old clothing can transfer color onto light color leather and dark leather can
transfer color onto light clothing. As the bag and the clothing rub against each other,
the friction and the heat/moisture promote the problem.
Despite this all.... enjoy your new treasure.
