Louis Vuitton has become synonymous with quality and luxury in the handbag world. Whether your piece is a new Mahina leather shoulder bag or a vintage monogram bucket bag, it is made from quality products -- including vachetta leather. Vachetta is a type of untreated leather used to make the handles and tags of your Louis Vuitton bag, and proper cleaning will prevent unsightly water marks.

Soak a soft cloth with water and wring out until damp.

Add 1/2 teaspoon of saddle soap to the damp cloth. Rub the cloth against itself until the saddle soap begins to lather.

Work the saddle soap into the Louis Vuitton handle, using overlapping circles, until both sides of the handle are clean.

Soak a second soft cloth with water and wring out until damp.

Wipe off the saddle soap with the damp cloth.

Place the purse in a cool, dry place until the handle is completely dry.

Cover the handle of the bag with a layer of leather conditioner to restore the leather and help prevent any cracks from exposure to heat or moisture.
