No need to panic if your pen nicks the arm of your leather chair as you jot down down a note. The solution is in your fridge. Simply dampen the corner of a paper towel with milk and blot until the stain disappears. Then wipe the area clean with a damp sponge. The milk’s enzymes break down the oil that bonds inks to the fabric. Plus, the milk’s protein moisturizes the leather, making it as soft as ever.
