Blot away spills as quickly as possible after they occur. Wipe away grease with a dry cloth and baking soda. Use rubbing alcohol to address ink stains on your leather furniture. Dab away juice and soda stains with a clean cloth and distilled water. Mix together lemon juice and cream of tartar to clean beige leather.
As soon as a spill happens, grab some clean paper towels to wipe away the bulk of it. Once that is done, take a clean, dry washcloth and blot the stained area by pressing down on it repeatedly. Blotting the spill should help draw up any liquid or matter that has already started to set into the leather. If your leather is stained with butter, body lotion, oil, or any other kind of grease or fat, use a dry washcloth to wipe off as much of it as you can. Once the grease has mostly been removed, sprinkle enough baking soda over the stain so it’s completely covered. Leave the baking soda on the stain for 2 to 3 hours, then wipe it away with a clean cloth.  Don’t use water to wipe away grease stains. Water could actually cause the grease to set into the leather, rather than clearing it away. The baking soda helps draw the grease out of the leather, making it easier to wipe away. Dip a cotton ball into rubbing alcohol and gently squeeze it out so it’s not dripping wet. Then dab the cotton ball against the ink stain to remove it from the leather. Dab in an up-and-down motion, rather than rubbing the area. Stop once the stain has been lifted. Depending on how big the stain is, you may need to use more than 1 cotton ball. The stain should transfer from the leather to the cotton ball, so when you notice the cotton looks stained, trade it out for a fresh one. Dampen a clean cloth in distilled water, and blot any areas on your leather furniture that have been stained by water-based liquids. After the stain has been blotted, leave the spot to air-dry. The water and cloth will clean away any stickiness left from the liquid. Mix together 2 tablespoons (30 mL) of lemon juice and 2 tablespoons (30 mL) of cream of tartar in a small bowl. Spread the mixture over the stained area. Let it sit for 10 minutes, and then wipe it clean with a damp washcloth. Don’t use this method on darker pieces, as the lemon juice could lighten the leather.
