Removing Coffee Stains from Porcelain Sinks

• 1). Pour distilled white vinegar into a clean, empty spray bottle. Spray down the stained porcelain sink with the vinegar.
  
  
• 2). Let the vinegar soak on the stain for about 15 minutes. Scrub the area with a soft scrub brush.
  
  
• 3). Rinse the sink with a rag and plain water. Go over the area with a dry rag.
  
  
• 4). Mix up an oxygen bleach solution into a bucket for tougher coffee stains. Mixing instructions for oxygen bleach may vary depending on the amount of sodium percarbonate in the product. In general, mix together 2 oz. oxygen bleach per ½ gallon of hot water.
  
  
• 5). Saturate a rag in the oxygen bleach mixture. Lay the rag on top of the coffee stain. Let the rag sit on the sink for 15 minutes.
  
  
• 6). Remove the rag and scrub the sink with a non-abrasive sponge. Wipe down the sink with a rag and plain water. Dry thoroughly with a clean towel. Repeat the oxygen bleach application, if necessary, until the coffee stain is gone.
