How to Remove Set-In Coffee Stain from a White Porcelain Mug

Step-by-Step Cleaning Instructions

• Pre-rinse and initial soak: Start by rinsing your porcelain mug with warm water to remove loose coffee residue. Then, fill it with hot water and add a few drops of a gentle dish soap. Let this solution sit for about 10-15 minutes. This soak helps to loosen the entrenched coffee stain.
• Gentle scrubbing: After soaking, use a non-abrasive sponge or soft toothbrush to gently scrub the stained areas. Work in circular motions to help break up the set-in coffee. Avoid using harsh scouring pads that could scratch the delicate porcelain finish.
• Targeted stain treatment: If the stain persists, create a mild cleaner by mixing warm water with a small amount of white vinegar. The vinegar’s mild acidity can help break down the stain without damaging the mug. For a slightly thicker consistency that clings to stubborn areas, you can combine a small amount of baking soda with water to form a paste, then apply directly to the stain. Allow it to sit for a few minutes before gently scrubbing again.
• Final rinse and inspection: Rinse the mug thoroughly under warm running water to remove any soap or cleaning residue. Inspect the stained area and, if necessary, repeat the gentle scrubbing or stain treatment until the coffee spot is no longer visible.
• Drying: Dry the mug with a clean, soft towel. Air-drying is fine too, but using a towel minimizes any water spots and helps maintain the shine of your porcelain.

These steps focus on breaking down the residue behind the set-in stain using safe methods that respect the integrity of your porcelain mug. Remember, patience and gentle techniques go a long way in reviving your everyday items without compromising their finish.
