Leather desk tops can receive a multitude of abuse from ink marks, white water rings left from beverage glasses and neglect, allowing the leather to lose its lustre. Leather requires regular conditioning to stop the drying process and keep it from cracking. Restoring leather involves removing stains and adding emollients. Once restored, keep your leather desktop shiny by applying oils regularly.
Pour 1 to 2 tsp non-acetone nail polish remover onto a white paper towel. Wipe the paper towel over any ink stains on the leather desktop. Remove the stain and the nail polish remover with a clean paper towel.
Spread mayonnaise over white water ring stains on the leather. Rub the mayonnaise into the stains with your fingers. Leave the mayonnaise on the leather for two hours. Wipe the leather clean with a damp paper towel. Dry the leather with a clean paper towel.
Mix 1/4 cup white vinegar with 1/2 cup linseed oil in a bowl. Stir the mixture with a spoon to disperse the ingredients properly.
Dip a clean microfiber cloth in the mixture. Wipe the cloth over the entire leather desktop. Apply the mixture generously to the leather. Allow the mixture to remain on the desktop overnight.
Buff the desktop the next morning with a clean microfiber cloth. Use rotating motions as you wipe to create a shine to the leather.
Condition the leather desktop once or twice a month by wiping with straight linseed oil.
