1. Wipe down your leather furniture with a clean, white cloth once a week. The white cloth not only removes dust and debris, it doesn’t leave behind any dyes like colored washcloths could. They also make it easy to see when you have removed every speck of dust.
2. Vacuum your furniture once a month or so to remove any deep down dirt or grime.
3. To nourish the leather, mix together two parts linseed oil with one part white vinegar. Mix or shake this "hide food" thoroughly. Pour a little bit of it onto a soft cloth and gently wipe the surface of your leather furniture. Work in circular motions until the entire surface is covered. Allow the furniture to sit for about 10 minutes and then buff the leather with a soft cloth until it's shiny.
Clean your leather furniture with a damp, soft cloth. Just be sure the cloth is damp and not soaking wet. For tough dirt and grime, use a gentle moisturizing soap like Dove or baby shampoo. Lather the soap on with a cloth, being sure not to over-wet the leather, which can damage it. Do not rinse off the soap, just buff it away. The soap actually works as a leather conditioner. Never use strong detergents, alcohol or harsh chemicals to clean your leather furniture. All of these can permanently damage it.
For Spot Removal:
- Ink stains: Remove stains like ink by dipping a cotton swab in rubbing alcohol or non-acetone nail polish remover. Gently rub the spot until it disappears (this might take a couple of tries) and then blow dry it on the lowest setting. If the stain is particularly stubborn, rub a thick coat of non-oily, non-gel cuticle remover onto the leather. Allow it to sit overnight and then gently wipe the stain away with a damp cloth.
- Dark stains: Dark and protein-based stains (like mud, blood and food) can be removed by mixing together a paste of one part cream of tartar and one part lemon juice. Rub the paste into the stain and allow it to rest for 10 minutes. Add another layer of the paste, really rubbing it into the stain and then remove it with a damp sponge. Buff the leather with a soft cloth until it's dry.
- Water stains: Water rings and stains can be removed with mayonnaise. Just apply the condiment in a thick layer and allow it to sit for a couple of hours. Wipe the mayo off (along with the water stain) using a dry cloth and allow the leather to dry.
