Remove Stains from Mugs
Step 1
Mix 1 to 2 tablespoons each of baking soda and distilled white vinegar or apple cider vinegar inside your coffee mug. Add 1/4 cup of hot water. If cleaning a stainless steel, thermos-style mug, close the lid and shake vigorously. The baking soda acts as a stain eliminator, while the vinegar serves to deodorize.
Step 2
Scrub the entire inner surface of your mug — not just the stains — vigorously with a toothbrush or sponge. Scrubbing all the surfaces ensures complete removal of any lingering coffee odors.
Step 3
Rinse your mug with hot water. Allow it to dry. The vinegar scent may linger while the mug dries, but will disappear after a short time.
Remove Stains from Fabric
Step 1
Add 1 teaspoon of white vinegar to one quart of water and mix well. Scrub the coffee stain vigorously with a cloth or sponge until the stain breaks up and disappears.
Step 2
Place your clothing or fabric in a conventional washing machine if the vinegar and water procedure fails to thoroughly remove the stains. Add 1/4 cup of white vinegar, along with your preferred laundry detergent. Do not use bleach, because it will react negatively with the vinegar.
Step 3
Place your clothing or fabric in direct sunlight to dry. Use a commercial dryer if no sunlight is available. It is essential that the clothing or fabric dries completely to prevent mildew from forming.
