Your dishes, bowls and mugs can accumulate metal marks from your silverware. Each time you stir your coffee or other liquid in your mug with a spoon, small metal marks are left on the mug's surface. The metal marks are black or gray in color, and dishwashing liquid alone won't remove the marks. You need a substance that can break up the mark without damaging the mug's surface.
Things You'll Need
- 2 soft, non-abrasive cloths or towels
- Non-abrasive cleanser, such as Bar Keeper's Friend or Earth Friendly's Creamy Cleanser
- Warm water
- Dishwashing liquid
